Parallels, a Harry Potter + Percy Jackson and the Olympians Crossover fanfic

Harry's footsteps felt like lead as he walked through the forest floors. He tried to count his heartbeats as he walked to impending doom. The adrenaline rush from the battle started fading away from him, making his injuries' presence known. The snitch was cold in his hands as he circled it with his fingers. Bringing it to his mouth, the words engraved on the snitch got more pronounced. "I open at the close."

"I am ready to die." He gulped, forcing the words through his mouth. The Resurrection Stone rolled out of it, gleaming in the moonlight filtering through the forest trees. He rolled it twice in his hand and 5 figures shimmered into existence around him.

"Mom, Dad?"

"Hello Son," said his dad.

"My sweet little boy, you've grown into a fine, brave, young man. Nothing could have us any happier than being able to witness it, alas every person has his destiny." Spoke his mom.

"I just wish we all had time together, but all of you guys died and Sirius spent most of his life in Azkaban, all because of a dumb prophecy"

"All were things you never had a hand in, Harry."

"But your son, Remus. Now he's an orphan, and his godfather is about to die too."

"One day he'll understand, like you did. If he grows to be like you, I'll be the proudest father ever."

"Eh, enough of this morbid , for fucks sake, did you kiss Hermione yet," asked Sirius. Harry shouldn't have been surprised Sirius would ask that.

"No." He saw the light fading Sirius's eyes. "She kissed me." His mind went back to the events that lead to what Harry knew were the best days of his life.

He ran through the aisles, Hermione's hand in his and Neville beside them. Two death eaters appeared in front of them.

"Avad-," one started.

"Bombarda," shouted Hermione. It hit one of the death eaters, sending him crashing into the opposite wall. The other one started waving his wand.

"Silencio," said Harry.

"Good job Harr-," The death eater kept waving his wand and sent a purple streak of light. Hermione crumbled to the floor with a soft "ooh".

"Expolso," cried Harry. The spell hit him straight in the guts crashing him against the wall. He joined the other death eater on the floor. Harry and Neville rushed towards Hermione. Harry held her lifeless body against his shoulder. Please don't be dead, anyone but you, please. Harry couldn't breathe. His heart felt like it's been ripped out.

"There's a pulse Harry, I'm sure," said Neville. Harry felt lightheaded, wanting to scream for the rest of the night, but they were still stuck in the department of mysteries with no help coming for them. He looked at Neville and saw that his wand was broken.

"Harry, I'll carry Hermione, let's find the others and get out of here," Neville interrupted him before he could even start.

The rest of the night was a blur; the order's arrival, Sirius's death, the prophecy, and knowing that he was the only one capable of killing Voldemort. All were thrown into the back of his mind, as he sat on a chair next to her bed in the hospital wing. Madame Pomfrey had tried to shoo him away, but he was adamant on staying with Hermione. He glanced up and saw that she was stirring. She opened her eyes lazily and saw him over her.

"Harry?" Her voice was groggy and tired. She sat up and looked around her. "When did I get here?"

"You were knocked out, some death eater sent a curse at you. Y- you nearly died." He stuttered the last part. He held her eyes and was surprised to see the calmness in her eyes.

"Well if death is that near to us, I guess I'll do this," She then promptly grabbed his face and smashed her lips into his.

He came back to the present seeing Sirus's grin come up in full scale. "Ha, knew that girl was something else! See that, Remus? I told you he was smitten with her." Harry smiled at his "family". This was the life he was supposed to get but wasn't granted. Their laughter had quietened down, and they were all looking at him.

"Will you stay with me?"

"Always."

He hid the resurrection stone in his pocket when he heard footsteps behind him. His stomach dropped when he saw it was Hermione

"What are you doing here," Harry hissed at her.

"I told you I am not going to leave you. I'm coming with you whether you like it or not. No dark lord is going to take you from me," she said resolutely. Harry grabbed her hand and dragged her behind a tree.

He had his back to a tree as he held her shoulders. "Hermione, please don't make this harder for me. I am going to die for you to live. Just please, go back and kill the snake, it's th-". Harry was never able to finish his sentence as he and Hermione were both sucked into the tree, falling into nothingness.

I was in utter shit. Annabeth and I had agreed to meet up in the skating park at noon and I was nearly half an hour late. Knowing that that dam (long story) professor already assigned me an extra 1000 word essay because I was late to hand in the other one didn't help my mood. Honestly who could blame me? If you didn't already know, I am a demigod. Long story short, it sucks. Apparently demigods have a smell that attracts all types of monsters that want to challenge and kill you. Like, dude, can't you get a better life? Anyway, most demigods are dyslexic which makes writing essays harder, since all the letters keep swimming in my vision; Fun stuff. I am also diagnosed with ADHD which only gets worse when something that interests me is around, and the subject of that interests is always mainly my girlfriend Annabeth Chase aka "Most Badass Person Ever". For instance I was sitting on her roomate's bed ready to complete said assignment with the least amount of work, when Annabeth comes in wearing one of my hoodies and well you can probably guess what happened next. Yep, we made out for the rest of the night, and the assignment lay forgotten. Hey, don't blame me, Annabeth just has that effect on me. She just has those bright grey eyes, which always give out which mood she's in, and her blond cur- , you get the idea. See all that long ass monologue about a bunch of random unrelated topics, that's ADHD for you; Cool, isn't it? Anyway, I'm late and trust me, if you ever had a meeting with Annabeth, not a date that's reserved for me, and got there late you can only be saved on one condition. That is to be me, and you aren't, so tough luck. Anyway here she is, she's wearing black jeans and a white hoodie with a denim jacket adorned with a blue and white pair of crossed wings and on her feet were the skates I got her last Christmas. She caught my eye, and I could see the amusement in her eyes, but she tried to hide it with an emotionless mask.

"Why are you late? And why were you riding your skateboard that fast; you could've crashed," she said coolly while raising her eyebrow.

"Well, the professor had some words to say to me for that late assignment, and to answer your second question, I didn't want to leave you waiting any longer." I said with a pout, bringing my hands together in a pleading position, and I knew she was about to cave in, when I saw her eyes lighten. Regardless, she crossed her arms around her chest.

"It's not going to work," but I could see her fighting back a smile. I grinned and leaned down to kiss her. At that she full caved in and reciprocated wounding her arms around my neck. See, none of you could escape her wrath. Only I could. We broke apart and started skating slowly around the park talking about everything and nothing. Since we started college in New Rome, and our lives became monster and pro-, no scratch that, monster free, life has been almost perfect. I glanced at Annabeth. Seeing the look of concentration on her face, I knew she was thinking along the same lines as I was

"You're thinking about the prophecy, aren't you?" I said knowingly. She looked up at me and I could see her eyes darkening a bit.

"Yes, that prophecy. You remember how it all happened. I just can't help but think that's it's about us again.

"Yeah," I sighed, I remembered it all too well

The sun was setting over the horizon as the war high finally settled and the adrenaline rush started seeping from the camper's bodies. Campers littered around the valley, all contemplating the events of the past 24 hours. I sat on the Poseidon table overlooking the canoe lake. Yeah, life was definitely going in the right direction. I glanced down at Annabeth. She had her head on my shoulder with her eyes closed, glad to finally be able to relax. I put my arm around her and she snuggled into my side. I could still smell the lemon scent in her hair, which pulled me into comfort. I could see Rachel and Ella coming over. They sat down at the table with Chiron and started chatting with him about stuff I couldn't care less about. Then things went extremely wrong. Ella started screeching and flapping her wings wildly, while green smoke started oozing from Rachel. Campers rushed to them, trying to keep Rachel from falling on her head and trying to get what the hell was going on. The smoke around Rachel ceased a bit. Both Rachel and Ella spoke in the same monotone voice:

Three worlds after the downfall collide
Merging into hidden paths of the fourth
Two freed from eternal pain
Two break a morbid past
Ancient chains doomed at last
At the verge of death
A sacrifice of heart awaits
Powers denied, finally untied
Will they be able to abide
And save a world of pain
And the heroes finally reside
Their fates eternally intertwined

Dread filled my heart as I realized another prophecy has been made. Annabeth and I locked eyes and we realized another prophecy was hanging on our shoulders. Again!

Yep, that's the jest of it. Another prophecy from the fates designed to make my life hell. But hey, it's been two years and nothing has happened, so maybe, just maybe, this prophecy isn't about us.

"You know it might not be about us, it's been two years already," I said, resting my head on a tree in Bacchus's garden, as we laid to take a break. Annabeth sat beside me and started speaking.

"But, how can we be so sure, like, the last one started literally less than 6 months after Kronos's prophecy," she said desperately.

"We can't," I deadpanned." "We'll just get through it together as we always do."

She smiled and laid her head on my lap, "Yeah, together till the end."

It was either the fates were playing a cruel joke, or that I have the most rotten demigod luck in the world, because the moment she said those words, I felt myself getting sucked into the tree and Annabeth along with me. Oh yeah, I forgot to introduce myself. I'm Percy Jackson. A twenty year old who apparently is going to die, not from monsters as I always assumed, but from a tree that likes to suck humans for fun.

Eren woke up as he heard a faint noise coming from downstairs. He looked at the other side of bed and saw that Mikasa was missing. He relaxed, realizing it was her, probably going for a glass of water. When she didn't come back for the next 10 minutes, he started getting worried, so he got up and changed his clothes, and went down to check on her. He didn't expect to find her sitting on the kitchen floor, her head on her knees breaking down in tears. He rushed to her side and her sobbing doubled. He wrapped his arms as she cried into his chest. After her sobbing quietened into soft sniffles, he thought it was right to ask her what was wrong.

"Hey what's the matter?" he asked softly. She looked up at him and he could see her fighting back tears. He wiped her tears with the palm of his hand. She fiddled with her scarf and started speaking softly.

"I- I just don't want you to go," she said softly looking up at him. Oh, so that's what it was about. He and Mikasa had already spoken about the topic many times. He was going to die in a few weeks, and that always was a subject of Mikasa's nightmares. He thought he should comfort her with words, but he knew they'll all be in vain. He opted for another option.

"Hey, c'mon let's go on a walk," he said, standing up and pulling her up with him. She looked at him, probably trying to find out what he was up to. He just held out his hand, and she squeezed it. They strolled through the night light of Shiganshina silently, basking in each other's presence. They reached the outskirts of the city, and found a familiar tree sitting at the middle of a small slope. As they walked towards it, Eren contemplated what had happened in the last 4 years. He had in fact unleashed the rumbling on a weak scale. If he hadn't done that, Paradis Island and all of its population would've been wiped out entirely. He recalled the night he had changed his plans of completely wiping out the human race outside of his island. Without that night, Eren would've probably been dead already.

He was standing on the outskirts of a refugee camp overlooking the people who had, like him, lost their homes and family to a war that wasn't theirs. A war that shouldn't have happened in the first place. He hated that he saved that kid from the merchants. Yes, the kid deserved to be saved, and he loved the way his eyes lightened with joy when it dawned on him that he wasn't getting beat up. On the other hand, what would that make him? A liar? A hypocrite? Or a devil's spawn with no mercy in the slightest? He felt footsteps behind him, and was sure they belonged to Mikasa. He turned, and sure enough Mikasa was walking toward him with a worried look on her face. He turned back to look at the camp and a tear fell from his eyes. He tried to hastily wipe it, but he knew Mikasa had already spotted it. She came to a halt next to him.

"Eren, you shouldn't have left alone. You are the enemy's biggest target." She said sternly. He tried to keep his emotions in check. He tried so hard, but he couldn't do that with Mikasa, not her.

"Why Mikasa, why is it that you care so much about me." He knew he had startled her, her breathing had quickened, and her eyes widened. "Is it because I saved you when you were a kid? Or is it because I'm family? O- Or do y- or do you love me Mikasa?" He said the last one with such desperation that he broke down in tears. He hated himself, hated that he had indirectly confessed to Mikasa, hated his plan, and he especially hated that he couldn't keep his emotions in check, and he was now going to cause Mikasa even more pain when he eventually dies. He looked at her and saw her opening and closing her mouth trying to form a sentence.

"What am I to you, Mikasa?" He said weakly, waiting for her to say something, anything.

"My most beloved. My dear," she whispered. He looked up at her and saw that she was smiling softly at him, with tears in her eyes. "You are everything to me, Eren. You've been with me ever since we were 9 years old. We've fought titans with each other since we left Shiganshina. And most importantly, yo- you wrapped my scarf around me, and promised to forever wrap it. I love you with all my heart, Eren." She said while smiling softly at him.

looked at her and did the only thing his mind was able to comprehend at the moment. He grabbed her face and kissed her. She made a surprised sound, but it didn't take her seconds to start kissing him back. It was a simple kiss, and Eren was on cloud nine. A cough from behind them caused them to break apart. They looked back and saw their friends from the Survey corps staring at them. Connie, Sasha and Hange were laughing and making kissing faces at them. Levi looked disgusted, and Jean had a neutral look on his face. However, Armin's look is what they both were surprised to see. He had a smirk on his face, which was very weird to look at, because Armin never smirked. He had an air of triumph in him when he said "Finally you two, I thought I would have had to trap you on a deserted island."

They both sat down at the tree. Eren started gently playing with Mikasa's hair.

"Mikasa, you know how it is. There's just no stopping it. I love you, but there's just no escape from it. I promise you, I'll be with you till my last day" he said softly. Mikasa let out a sob and he held her. He felt a prickling sensation at his back, and suddenly he was being sucked into the tree. Mikasa looked up alerted at him, and in a second, both of them were sucked into the tree.

"Hey Hiccup," He looked up and saw Astrid walking towards him, while he was in the forges working on a new tail for Toothless. He's been there since dawn, nothing out of the usual.

"Hey you," He said giving her a kiss. "What brings you here to my humble residence?"

She smirked at him, probably contemplating whether or not to punch him. She seemed to have chosen the latter, because she came to sit beside him.

"The dragons have all been acting weird today. They're constantly fidgeting, and their necks suddenly snap west, then they're back to normal". Hiccup stared at her, trying to scrutinize the meaning of this. He couldn't think of any reason why would they do that unless…. An idea burst through his mind like a meteor. Yes it made sense. How did he not think of this before? He jumped from his seat and sprinted to find Toothless.

"Hiccup!" He heard Astrid shout behind him as she ran after him. He raced through New Berk and found toothless sprawled on the grass.

"Hey buddy," he said scratching his neck. Toothless stood and rubbed his head against Hiccup's torso. "I think I know how we could find your girlfriend, and I think you realize it too." He was checking the tail when Astrid caught up with him.

"Where are you going?" She asked breathless from her run.

"I think I know how to find the hidden world," he said and turned to look at her, smirking. "You coming?"

"You bet," she said smirking back, and in a puff of wind they were gone.

During the flight, Toothless's neck kept snapping in random directions. Hiccup was now sure that the hidden world couldn't be reached without a dragon, similar to the first dragon cave he found. They were flying for almost an hour, and fog was surrounding them from all sides, when Hiccup spoke.

"Hey buddy, we've been flying for over an hour, you sure we're on the rig-, WOAH!" They had broken through the fog and a jagged waterfall the size of an island revealed itself. Toothless was as enthralled by it as much as Hiccup and Astrid were. They flew down and were sucked into an underground pit. The bottom was filled with black rocks reaching nearly fifty meters high. Ducking under a tunnel, the three of them went slack-jawed. A cavern stretching endlessly was at the end of the tunnel. It had the same type of rocks that were in the pit on the other side of the tunnel, however, this one was littered with eggs and small dragons that shined and made a colorful pattern mesmerizing the three. And dragons were everywhere. All the tamed and untamed combined were flying in a space circling around the center rock, which unlike the others gleamed white, and looked like a throne. A white paw climbed on the rock, and Hiccup's breath got caught in his throat. Toothless made a sound in the back of his throat. The light fury had climbed on top of the rock and was surveying the dragons around her. She roared and all the other dragons followed, causing goosebumps to appear all over his body. Out of nowhere Toothless's eyes narrowed and he jeered upward towards a small circle of fog at the roof of the cavern that had escaped his vision. The dragons took notice of them and started following them, but none, not even the light fury, managed to catch them, as all 3 of them were sucked in, and the fog sealed.

Hiccup looked around him and saw that he was in a room. About a 100 square meters. The walls were made of fog with three doors on each wall. There was no roof whatsoever. It seemed to stretch endlessly. A cauldron sat in the middle of the room with a bronze dagger at its edge and a book on leaning against it. The cauldron was about 3 feet tall and wide enough to fit Toothless's head inside. Astrid was scrutinizing it intently.

"Where are we?" Not a second later, a blinding light filled the room. The three inhabitants turned away and closed their eyes. They heard the sound of bodies tumbling, and when the light had faded, he looks back and saw something that would've cracked him up if he hadn't been completely flabbergasted. Six people, two out of each door were laying crumpled on the floor. Hiccup got a good look at the couple on the right. The guy had jet black hair and sea green eyes. The girl had curly blond hair and steely grey eyes. The six strangers stood up, and all of the inhabitants of the room stared at each other and tensed.

Oh hello, You're back. As I was saying, weird stuff has been happening to me all my life. I fought in two wars. Killed monsters, gods, titans, and giants. I also survived Tartarus, which is the lowest pit of the underworld. However, this stuff was pretty normal in demigod standards, but even I can't explain how a second ago I was leaning against a tree, and now here I am in a room with 8 people I never saw in my life, and was that a dragon? What was even weirder, was the fact that all the other people in the room were as perplexed as I am. The two people in front of me were tense shouldered. The guy had emerald green eyes behind glass frames, and jet black hair similar to mine. The girl had bushy brown hair and brown eyes. She kept scanning her surroundings intensely. In front of the right door stood a girl with Asian features and shoulder length black hair and black eyes. She had her arms in a fighting stance, the boy had brown hair in a manbun and pale green eyes, with his hand near his mouth looking ready to bite it. However the weirdest ones were the couple on the left side of the room. The guy had a slightly auburnish brown hair and green eyes? Did everyone here have green eyes? The fates have to be playing a joke. The girl next to him had blond hair in a braid with tufts framing her face and steely blue eyes. Those two wore clothes that looked to be the fashion sense 200 years ago. I was about to speak when 3 ladies flew down from the roof that seemed to stretch endlessly. The dragon's eyes narrowed and he growled menacingly at the ladies. They paid him no mind as the lady in the middle spoke.

"Welcome heroes." Uh-oh I thought, this couldn't be good. Three ladies calling us heroes, and not only us, but also the other strangers, those are definitely the fates.

"You've all been brought to this room to perform a quest that will benefit each and every one of your worlds and personal lives." They all chorused. "Your choices will decide whether the prophecy becomes true and peace spreads throughout the 4 universes." What in the gods' names were these ladies talking about? Universes? Worlds? Peace among the worlds? My head was spinning like crazy, but my breath halted when the ladies spoke the lines that have been plaguing my nightmares for 2 years

The fates disappeared in a flash of light and left us with the 6 strangers, a dragon, book, dagger, and cauldron.

"Alright," said the guy with glasses with a heavy British accent. "What were those things, and who are you people?"

"The fates, and I'm Percy. She's Annabeth, my girlfriend," and I said.

"What are those fates?" Said the Asian girl. All eyes were on Annabeth and I right now.

"They're the ladies in control of the metaphorical thread of life for every living thing from birth to death," said Annabeth

"I read about those ladies in Greek mythology books," said the brown haired girl. "But, they're supposed to be myths." She seemed to notice the book leaning on the cauldron. She took a step forward towards it, but the black dragon narrowed his eyes at her and growled. The guy took out a stick? From his pocket and readied it on the dragon

"Okay, I think we're all confused here, so let's calm down and talk this out." Spoke the auburn-haired guy. "Come on buddy, calm down," He told the dragon.

"We'll go first, My name is Astrid, He's Hiccup, and the dragon's name is Toothless". She said. I was about to comment, when I felt Annabeth's stern gaze on me and bit back the comments. Her gaze went to the cauldron and her eyes widened. I didn't have time to look at what got that reaction out of her, because someone started talking.

"I'm Harry," "and I'm Hermione," said the two in front of me

"I'm Eren, she's Mikasa," said the guy in a manbun.

"Okay, now that the introductions have been made, does anyone know why are we here," said Hiccup

"I think we know a bit, that prophecy, we heard it two years ago," I said.

"Another prophecy?" Said Harry but stopped with a look from the Hermione. Was this guy a demigod? No, he had a stick like Karter's one. He might be a wizard as well.

"Maybe we should read that book and see, it might be able to tell us what's all this about," said Mikasa. He saw Hiccup whispering to Toothless as both Hermione and Annabeth went to the middle of the room. Hermione grabbed the book and Annabeth grabbe- was that her dagger? No way, it fell into Tartarus. It can't be.

"Percy, it's here. How did this come here?"

"Is it yours?" Asked Eren. All the others had crowded around Hermione to get a better look at the book.

"Yes, but I lost it two years ago." Everyone's attention turned to Hermione and Astrid as they started reading.

"To break the chains of the past, to prevent the ultimate release of ancient evil powers, and to eliminate present foes, sacrifices must be made. Heroes, this book has been found between the four alternate realities, guiding two heroes from each world. Combining demigods, vikings, wizards, and eldians, to assist in the elimination of the current threats, that if combined would cause disruption. You are now at the heart of the four worlds." read Hermione. Everyone looked up, there were four realities. And they were all here. We were chosen to eliminate the threats from our worlds.

"To accomplish this, the potion on the next page must be perfectly prepared. There is no room for failure. If you fail, every single evil force ever gracing your worlds will be resurrected to accomplish what generations of heroes, including you, have stopped them from doing," read Astrid. Well, no pressure, I thought mockingly. We're just asking you to save the world. And from the looks of it, those guys had probably gone through as much as Annabeth and I did.

"What are these potions ingredients?" Asked Eren.

"How can we even make a potion? None of us came with any ingredients." Said Harry looking around for a confirmation

"It might be made of stuff we already have with us, that's the only logical assumption." Said Hiccup.

"Let's just keep reading and find out," interrupted Mikasa. She started reading from there. "This potion will not require any plants or chemicals mixed, it requires sacrifices of heart that only a handful of people from each world could handle." Silence filled the room as lines from the prophecy went through their minds

At the verge of death
A sacrifice of heart awaits

"I think we should keep the reading of ingredients after we say everything, and I mean everything," Astrid said looking around the faces.

"Yes, it's for the better." Harry and I said simultaneously. We grinned at each other, and I thought maybe this wasn't too bad.

"So I'll start, Annabeth and I are the ones from demigods world apparently. As Hermione previously said. All the Greek and Roman stuff they're all real"

"Yes, Zeus, Poseidon, Athena, and all the Olympians are real. 8 years ago. A friend of ours was manipulated by the titan lord Kronos. He was freed from his prison in Tartaus, seeking revenge on the Olympian gods. We and our friends from the camp we train in, stopped him. Kronos had by then used the mortal body of our friend as a stepping stone before he can assume his true form."

"Yes, the dagger that Annabeth found here. Our friend had given it to her when she was little, and it was the only blade that was able to defeat Kronos, because he broke his promise to her, so it became cursed". He noticed Harry and Hermione flinching at the word "prophecy" but paid it no mind. "Anyway, this defeat woke up Kronos's mother Gaea, who we fought three years ago with other demigods. This goddess called Hera thought the only way to defeat the giants was to make us and the roman camp work together. So she kidnapped me, erased all my memories except of Annabeth, and kidnapped a demigod called Jason, erased his memories, and placed us at each other's camp. There was a prophecy about Annabeth and I and 5 other demigods including Jason that we had to sail to Greece to save Olympus. Along the way, we realized we couldn't defeat Gaea unless we closed the doors of death. One of those doors was in the darkest pit of hell, Tartarus. No demigod had ever passed through it alive. Annabeth and I fell into it. We closed the doors with the help from our two friends Bob and Damasen, and our friends closed them from the other side. We had battles with Gaea and her forces and we eventually won. And it seems like, that if we failed in making this potion, Gaea and Kronos will both rise and we'll be doomed.

"Prophecies suck mate, they keep ruining lives everywhere," said Harry. I laughed.

"Then since you're demigods, whose children are you?" asked Hermione

"I'm a son of Poseidon and Annabeth's a daughter of Athena." Hermione was about to ask something when Hiccup spoke up

"Well if the Greek and Roman gods are true, does this mean that the Norse ones like Thor and Odin are real too?"

"They are in our reality. My cousin is the son of Frey, but they might not be yours," Annabeth shrugged..

"The tribe would have had a celebration, if it was confirmed Thor and Odin are real in our reality," joked Astrid

"This explains the sacrifice you have to make from the demigods world. That dagger , I assume, is important to you, Annabeth?" Said Eren. She nodded.

Mikasa's eyes widened as she focused on something on Annabeth's back " Eren, do you see that?"

"See what?"

"The wings on Annabeth's back. That's the sign of the survey corps." I didn't have any idea what the survey corps were, but if they had reached into our fashion world from an entirely different reality, then we were in a really serious situation.

Eren glanced at Mikasa, and an understanding seemed to pass through them.

"We'll go next," said Mikasa. "We were born and raised on an island surrounded by walls fifty meters high. We were told that humanity outside these walls was wiped out by beasts called titans, they were mindless monsters with different heights that roamed outside the walls and fed on humans. When we were ten, two titans attacked the outside walls of our village. One was taller than the walls that, he was able to throw boulders at the houses. The other had armor that was able to break the walls, so titans filtered through eating the villagers. We were able to escape, but Eren's mom couldn't." Towards the end of the story she held Eren's hand, and he continued.

"Two years after that, we joined the training corps along with our friend Armin and a bunch of people our age from other villages. Three years after that, we joined the branch of the corps specified to scout the titans and killed. Those are the suvery corps. Their sign is what is on Annabeth's back. This is where it gets complicated. After many missions and operations we found out that everything we were taught was wrong. For you see, one of our operations was to get back our village and find something from my dad's basement. Turns out there was humanity outside the walls, but our kind left the mainland and settled on our land, because we had the ability to turn into titans. Our memories were wiped out by the king. And all the titans roaming our island were actually eldians like us left on the mainland turned titans using spinal fluid of the eldians." He sighed not able to continue. Mikasa took over again.

"There is something called the 9 elder titans. Those are the ones able to shift between human and titan form at will. However, those can only live 13 years after they eat the previous owner of one of those elder titans. Eren's dad here had one of them and ate another one, the one that controls all the titans, the founding titan. At the time of the first break Eren's dad took him and injected him with the spinal fluid." She glanced at Eren, and he nodded." As a result Eren turned into a mindless titan and ate his dad, thus absorbing the founding Titan's power. He now had the ability to get the walls to assume their true forms as Colossal titans, which were the fifty foot tall ones, and end humanity. However, we only used it to threaten the people from the mainland to leave our island alone. And it worked, but Eren now only has." She stopped abruptly tearing up. Eren continued from there

"Now I only Have a few weeks to live, and our friend Armin 5 years." Mikasa started sobbing into Eren's chest as Eren held her

The others looked too stunned to speak. They all had gone through so much, but Mikasa's and Eren's story was truly heartbreaking.

"Then we'll save you". Everyone turned to Hiccup. "That's a line from the prophecy, isn't it? Ancient chains doomed at last. Those chains binding you and every titan shifter must be able to break."

"Yes," agreed Astrid. "And the lines at The verge of death, a sacrifice of heart awaits. That's what the fates meant when they mentioned the sacrifices. Each one of us must sacrifice something of worthy to save you and all the other eldians. It has to work". The more I thought about it, I realized they were right, Eren could be saved. Eren and Mikasa looked at them with smiles and everyone was surprised when Mikasa went and hugged Astrid. "Thank you," she whispered.

"No problem, Hiccup and I will go next."

"Yes, so we are the Vikings. Our island is called Berk. We are uh for the lack of better terms, the hooligans. In the last 300 years, Dragons kept attacking our island, stealing our food, killing our people, so we fought them. Every time there was an attack, Countless villagers and dragons were killed or captured. One of them was my mom, she got captured trying to protect me. Years went by and I was known as the shame of the village. The one who always messed up and disrupted the defenses against the dragons. Astrid, however, was the coolest kid in the village. She was the fiercest one of our generation. Anyway, there was this type of dragon that no one has ever seen. Toothless here is called the night fury. His type are the strongest, sneakiest, and most vicious type." We looked at the dragon sitting with his head in Hiccup's lap slobbering all over him and I couldn't help but compare him to Mrs.O'Leary. They were both the cutest friends, but from what hiccup says, they are also the most vicious when attacking. Astrid picked up from where he left off

"On the night of one of the attacks, Hiccup sneaked out and was able to trap Toothless. Poor Toothless got his tail broken from the fall. Hiccup found him in the woods, and like the softie he is couldn't kill him. Instead he freed him and nursed him back to health. He also made him a new tail, and they trained together. In the end Hiccup was chosen as the best junior dragon fighter for his "unique methods", and was chosen to kill a dragon in the arena. I was jealous, so one night I followed him and found his secret. Basically, they kidnapped me and flew me all over Berk. However, suddenly Toothless became irritable and flew uncontrollably. He flew with us to the nest where we found out that the dragons had a queen dragon that ate them if they didn't bring her enough food. She smelled us, but Toothless was able to get us out of there. Next day, when Hiccup was trying to tame the dragon in front of the whole village, his dad, who by the way is the tribe's chief, hit his hammer against the arena's cell, causing the dragon to go berserk and try to kill. Toothless showed up and saved him, but the secret was out. Hiccup then accidently slipped to his dad how to get into the nest, which prompted all the village to go try and defeat the nest. Naturally, they failed and this man right here gave me a heart attack, when I thought he was dead after he and toothless killed the queen.

"Hey, it wasn't my fault! Anyway our village then made up with the dragons and we let them live with us on the island. We then found another Dragons' nest, which turns out where my mom was all the time, taking care of the dragons. A savage called Drago then tried to capture that nest. He killed the king of that nest, using a king he tamed. We defeated him, now there's this guy called Grimmel who wants to kill toothless, because he killed all the other night furies. We just came here through the hidden world of the dragons. We were searching for Toothless's girlfriend.

"Dude that's so insane," I said. Hiccup's and Astrid's adventures were quite the tale.

"Though, what are you guys supposed to sacrifice. Eren and Mikasa, you too? Do you guys have anything as important to you as Annabeth's dagger?" asked Hermione

"I know what we have to sacrifice," Mikasa said. "Eren wrapped this scarf around me when he saved me from the people who killed my parents. It's the most important thing I own."

"I know too," spoke Hiccup. "We have to sacrifice our dragons, not in the same way as you guys. We just have to let them go live in the hidden world. The world isn't ready for them. That will also remove Grimmel's desire to come for us and I think after the potion's effect takes place, he won't even remember our location." He said, while looking at toothless who was looking back at him with the same sad eyes.

"I guess it's our turn now," said Harry. "We're from the wizarding world. Before I was born a prophecy was made about me being the only one able to kill the strongest dark lord. His name is Lord Voldemort. His real name is Tom Marvolo Riddle. One of his servants heard half of the prophecy, which was enough for him to hunt me and my parents down. They hid under a secret keeper charm which removed our house from sight. It could only be seen by those who the secret keeper told. Unfortunately one of my father's friends who was the secret keeper was a spy for Tom. He killed my dad and mom. But when he tried to hit me with the killing curse, it rebounded and he disappeared. No one knew what happened to him .My godfather was imprisoned because everyone thought he was the secret keeper and that he killed 13 muggles, non-magical people. And that traitor, who also killed the 13 muggles, had the ability to turn into a rat, he found a family and lived with them as a rat for 13 years. I, went to live my aunt and uncle, who pretended I didn't exist and tried to "beat the magic out of me". Obviously they failed, I went to Hogwarts, our magical school, and met Hermione and my other best friend Ron. At the end of that year, our headmaster told me Voldemort was still alive, and that my mother's sacrifice was what protected me that night and until I was 17 from him," Harry rested his head against Hermione's shoulder as he finished. She picked up from where he left off.

"In our fourth year, Harry was kidnapped and Voldemort used his blood in a ritual to resurrect himself. Harry managed to escape. Then when he tried to tell our Ministry, they shamed him on the news and tried to kill him and imprison him. Next year after Harry was able to throw Voldemort's possession with eye witnesses, they didn't have a choice but to accept that he had in fact returned. Next year, our headmaster told Harry that Voldemort had split his soul into 7 containers. That's how he didn't die. For the last ten months, we've searched for them and destroyed three of them. Harry had unknowingly already destroyed one in our second year, and our headmaster destroyed one which caused his death. Now only two are left, one is his snake. The other is Harry. When Voldemort's spell rebounded, a part of his soul was split, and it attached itself to Harry. This git was about to try and sacrifice himself, so Voldemort can die. But we just got sucked here, and now there's a way to end it all," finished Hermione.

"This makes sense, if the potion does its work, Eren should be able to use his founding Titan's power, and expel the Titan blood from all the eldians, and Harry will be able to get rid of the horcrux in his body. These two lines must refer to Hiccup and Astrid's situation, along with Percy and Annabeth. And save a world of pain, and the heroes finally reside. You both would be able to avoid wars and reside peacefully, and no more prophecies for Percy and Annabeth. Or Harry for that matter." Mikasa summed up.

"This definitely seems like it." Hermione said cheerfully "Now we just need to brew this potion." She opened the book and started reading out the ingredients. "Heroes, be extremely cautious, this potion requires a massive amount of stamina. The wizards have to be ready at a moment's notice. Their role is the most critical of them all. First, the cauldron must be filled with Godly Seawater. It must remain getting filled until the potion is done. It will act as acid, melting all the other other components, but beware chosen son of Poseidon, this will be the hardest feat you've ever done. It will drain your stamina which must be replenished by either, the wizard or the witch. Then a titan's flesh must be added to ensure the titan blood is eliminated from all the eldians. It is to be cut using the cursed blade. Drops of Ackerman blood must be poured using the cursed blade, followed by the sacrifices from each world. After all the sacrifices have been made, either the wizard or witch has to cast the spell "entraille eicio". After all of this has been done the potion will turn pitch black. Be cautious heroes, your farewells must be made before the blast of fire is sent, because after the blast lights the cauldron, an explosion sending you all back to your worlds will occur. Riders, the fire must be sent directly inside the cauldron, better take that shot from above. Final notice, this must be done in less than sixty seconds." Hermione finished perplexed. "What's Ackerman blood? And why that blood exactly?"

"Ackerman is my surname. Our blood is different than the other eldians. We were experimented on. As a result, we are not able to turn into titans, and the founding titan can't affect us."

"So Mikasa has to use my dagger and drop blood from it then drop the dagger in the potion. Now who's going to brew it?"

"I think Mikasa and Annabeth should be the ones to brew it," I said. "I will be busy providing the water. Astrid and Hiccup must be in the air ready to fire the blast into the cauldron. Eren will be busy transforming, and Hermione and Harry have to be ready at a moment's notice for the spells."

"Speaking of which, which one of us is going to do which spell?" Harry asked"

"You've always been better at improvising, so I think you should perform the expelling spell, while I perform the stamina one on Percy. I already practiced it, while we're hiding.

"Hold on, we're forgetting something." Interrupted Hiccup hastily. "What are Harry and Hermione going to sacrifice from the wizarding world."

Harry thought about it for a moment, then it clicked. He took out an old cloak and handed it to Annabeth." This was my dad's cloak, it gives you the ability to turn invisible. It's the only thing I have left from them. It must be it." We all looked at each other, and I realized every one of us was leaving something behind. "You guys are amazing, and this ironically turned out to be an amazing prophecy." They all smiled at me, then we got to work

We all surrounded the cauldron, except Eren who stood a safe distance away to transform.

"Ready," We chorused. I focused on summoning the water from my guts.

"Set," I felt the familiar tightening in my stomach, and the water trying to break free.

"Go," all of us shouted.

A stream of water exploded from my hand as it started to fill the cauldron. In a flash, Eren had transformed his hand into a monstrous size. Annabeth was at his side in a second severing his hand as it fell into the cauldron. I felt my strength draining, my knees began to buckle. Hermione seemed to notice, because I next thing I heard was a shout of "Stamina Restaurare" and I was able to keep providing the stream water. When my vision returned, I saw Hermione next to me with her wand trained at me, light coming out from it. Annabeth threw the dagger at Mikasa, as she unflinching cut a gash through her hand, spilling blood into the cauldron. So far so good I thought. Annabeth grabbed Harry's cloak and sank it into the cauldron, while Mikasa, after hesitating for a fraction of a second threw her scarf into it. Mikasa then proceeded to throw the dagger into it. She then went to help Eren stand again. Harry had his wand out in an instant. "Entraille Eicio." Hiccup and Astrid were already on Toothless's back ready to take flight.

"Hey guys, It's been a real pleasure meeting you," Astrid smiled

"Yeah, wish you could've rode a dragon with us," He smirked then flew off. Percy realized something was horribly wrong, when the ground under them started to shake, He looked at the potion and saw that it had turned a sheet of white, instead the intended black. Harry must've saw it too, because his eyes widened, and he seemed to realize something as he dropped his wand and started frantically looking in his pockets. We were running out of time, there was only about ten seconds left .Harry took out a stone with weird engravings on them and shouted

"HICCUP." He screamed. Hiccup didn't notice him, but Astrid looked at Harry. Harry seeing his chance threw it towards her.

"THROW IT BEFORE YOU FIRE," Harry screamed. Astrid took aim, and swiftly through the stone just a second before Toothless fired.

"Hey Harry," Percy called before the fire got the cauldron. Harry looked at him. "Get that Moldyshorts for me." We grinned at each other. The last line from the prophecy interrupted my thoughts.

Their lives eternally intertwined

Then everything went black.

Eren watched proudly from his seat, as Mikasa went up on the stage. She kept fidgeting nervously, as she looked around the crowd. This was definitely out of her comfort zone, but Eren had encouraged her to try it. Then the crowd went quiet as she started

She lost her brother a month ago
His picture on the wall
And it reminds me
When she brings me coffee, her smile
I wish I could be with her until my last day

She said She gave all her love to me (I said I gave all my love to you)
We dreamt a new life (We dreamt a new house)
Some place to be at peace
But things changed, Suddenly
I lost my dreams in this disaster

I'm crying
Missing my lover
I don't have the power
On my side forever

Eren had heard her sing countless times before, but as he glanced around, he saw everyone was staring at her mesmerized. He snickered as he saw Percy, Hiccup, and Harry trying to hide their tears

Oh Where is my lover
And I got no power
I'm standing alone, No way
Calling out your name

We don't know what is wrong tonight
Everybody's got no place to hide
No one's left and there's no one to go on
All I know is my life is gone

Eren saw Hermione, Annabeth, and Astrid smiling with tears falling from their eyes. They were probably the only ones, aside from him, who had heard her sing. She finished, and the crowd stood up clapping and whistling. Mikasa caught his eyes and smiled. Yes, life was perfect.
