A/N: This one will be painful for all Pertemis fans. I am sure of that. It will be very painful. Maybe I should get an extra layer of bunker just in case...

Here's chapter 7. Enjoy.

Luke's POV (a slight flashback)

Luke was in Elysium and he had been there for almost five years. He made peace with Beckendorf and Silena and was visited by Nico from time to time, but not often. Sometimes, he would receive news about the world above. He heard about the Romans, Gaia's uprising, the huge war between the gods and the giants. Then, a few months later, Luke heard about Percy's rebellious act against Olympus. He also heard about how Zeus was dethroned and there was a new King of Gods. What disappointed him but given him hope was the fact that Percy and Annabeth broke up. He was disappointed that Annabeth was hurt, but hopeful because he thought he would have a second chance with Annabeth.

Luke thought about going for the Isles of Blest, going for rebirth, but he had trouble getting in. The zombie guards stopped him, telling him that he wasn't qualified. Something about someone powerful and passport issues.

So, there Luke was, bored as hell as he sat down on the beach alone. The sea in Elysium reminded him of Percy, which made him felt guilty. Sure, Percy had forgiven him, but he hadn't directly apologized to him and the other Olympians.

Hermes . . .

He missed his father. He now realized why his father couldn't interfere with his fate. All those years of ignoring him and not helping him had a reason. If Hermes had helped him and interfered with his destiny, things would've gone wrong. Kronos might've won and Luke wouldn't be able to stop him. He finally knew why and had forgiven him. He just hoped that Hermes wouldn't beat himself too hard for his death.

He had made many mistakes in his life and he was willing to give everything to have another chance at life, just to ask for forgiveness. He stood up and made his way back to his house, but he was blocked by a figure.

The figure in front of him wore a black robe and was a bit shorter and slimmer than Luke. Luke frowned, because he had never seen him/her in Elysium before.

"Hello, Luke Castellan." The figure said with a feminine voice, so Luke figured it was a woman.

"Who are you?" Luke asked in a friendly-threateningly way.

"Now, now, there's no need to be rude. I think we need somewhere safe to talk." The woman said.

"It's Elyisum. This is the safest place in the Underworld for me." Luke said bitterly. He knew he couldn't return to the living world, so this was the safest place for any dead soul.

"I think I can manage that." The woman said. She flicked his hand and the scene around him dissolved, leaving nothing but darkness and emptiness. The ground beneath him felt solid, but he couldn't see anything clearly except for the figure, but even she was hard to see with the dark coloured robe.

"Really, who are you?" Luke asked in a more friendly way. If this woman could bring dead people away from the Underworld, Luke figured she must be powerful. Luke knew he was unarmed. He had lost Backbiter a few years ago when it got turned into Kronos' scythe. Now, Luke was facing a weird, crazy, dark powerful woman.

"I am the first being to ever existed, Lady Chaos." The woman said.

Okay, so maybe the woman wasn't crazy, but it was still weird. Luke didn't know if he should bow, look away, run or worship her. So, to stay safe, Luke greeted her with an intelligent, "Uh, okay."

Lady Chaos managed a chuckle, which was a relief. "So, what were you doing on the beach?"

Luke's shoulders relaxed a bit when Lady Chaos tried to start a conversation with him. "I was just thinking."

"About?"

Now, he was a bit annoyed. "My friends, my father and all the mistakes I'd made during my time alive." Luke didn't know why, but he didn't feel like lying at Lady Chaos. Even if she did asked questions about Luke, he knew that Chaos could easily peek inside his mind and know what he was thinking about.

"Do you have any regrets?" Chaos asked.

That took Luke by surprise. "I have, many of them."

Chaos nodded. She waved her hand and something flashed next to her. The first thing that crossed his mind was: an angel, because the figure next to her looked just like one. It was bald and had beautiful features that made Luke wonder whether it was a male or female, because it looked like both at the same time. Its body was well built and it glowed with a pure white angelic aura. What fascinated Luke the most were the angelic wings sprouting from its back.

"She, um, he, whatever, looks amazing." Luke marvelled. Chaos chuckled.

"Angels don't have any gender." Chaos said. "But it's still human. Well, not technically, but, you know."

So, they really were angels. "Why did you bring an angel here? And what's with the angels? I thought with the Greek mythology being real, angels and demons didn't exist."

"This will take some time, so you might want to sit down." Chaos offered. She snapped her fingers and a chair appeared behind Luke. Luke shrugged and sat on it. Chaos took a deep breath before speaking.

"Before the times of the Giants or Titans, as you know, Primordials ruled the Earth. Humans worshipped us in many ways, but communication wasn't really good back then. They didn't have fire or any ways to send their offerings to us, so I created them." Chaos gestured at the angel. "Angels and demons. Angels are created from my good prespective an the opposite can be said for demons. Angels and demons acted like demigods to us, doing errands and preventing unwanted things for us. We Primordials couldn't be in several place at a time, so we used angels and demons. When Gaia and Ouranus bred and had the Giants and Titans, we knew the angels and demons couldn't be kept around anymore. The Titans were power-hungry children of Gaia. So, I kept them locked up, sealed them away out of reach from any beings or deities."

Luke nodded. "So, why is this one here?"

"Well, there's another problem. You've probably heard about your friend's, Percy, rebellious act against Olympus, right?" Chaos asked. Luke nodded. "Well, one of my children took part in that. My daughter, Nyx, had caused some trouble ever since her husband, Erebus, had fathered a child who is now the King of Gods. Nyx wanted to do the same thing that Erebus had done to her so . . ."

"She's planning to have sex and get pregnant with another man?" Luke asked. Not really a possible wife candidate. "That's weird."

"What's even weirder was, Nyx chose to do it with Percy." Chaos said. That time, Luke wanted to throw up and laugh at the same time. He couldn't imagine that a Primordial like Nyx would want to have her way with him.

"That is truly disgusting." Luke managed.

"Of course it is. Anyway, after the war with Percy and the Olympians, Nyx is planning revenge. She hadn't done anything yet and the Olympians don't have a clue of what's going on. They think that they're clear of any threats and danger." Chaos explained.

"So, what do you want me to do about it? I'm dead, remember?"

Luke couldn't see her face, but he was sure that Chaos was grinning. "I'm here to offer you something Luke."

Luke gestured her to go on.

"I will let you have another life. There's no need to clean your memories whatsoever. You will go back to the world of the living as you are now."

"But?" Luke knew there had to be a catch if Chaos offered something that good.

"You have to follow what I tell you to do after this."

"And that would be?"

"You'd have to fuse yourself with this." Chaos gestured at the angel. "It has never been done before and I couldn't guarantee that you'd be able to survive it, but you have to do it. I need two breed of half human and half angel and demon. It's the only way you can win the war with Nyx, because you're helping the Olympians.

His mind was reeling with Chaos' offer. He wanted to go back up there so badly, apologize to everyone and make amends for all his mistakes.

"There's one more thing though. You can't show yourself yet. You will show yourself when the timing is right. I have looked into the future with Chronus and saw something unpleasant. Percy will die."

A sharp pain went straight through his heart. "He can't die! You can't allow it!" Luke protested.

"Calm down, Luke. This is why I said you can't show yourself to anyone yet. I will tell you a way to save him but you can only meet them and tell them about this after Percy's death."

Luke calmed down but the sharp pain in his heart won't go away. "Okay, I'm listening."

Chaos nodded. "After you merge yourself with this angel, I will send you back to the upper world. Nyx is planning to send Percy's soul to Tartarus."

"How do I save him from that?" Luke asked with slight anger.

"Like I said, Nyx is planning to send Percy's soul to Tartarus, whereas his body remains in Earth. You would have to open the Doors of Death in Epirus, where Percy could escape, if Percy could find a way there." Chaos said. Luke's mind processed everything in a second.

Without hesitation, he answered, "I'll do it." Chaos stepped forward.

"Luke, if I tried to fuse you with the angel, I can't assure your safety or your survival. I understand if you want to back out now. I won't force you into anything. I don't know if this will be painful or not or if the process is long or short. I simply don't know how long it would take and it is a huge risk and a gamble."

"If this gives me a chance to be with my friends again, I will do it no matter how small that chance may be.' Luke said confidently. Chaos nodded.

"Very well then. Close your eyes, this may sting a little."

Indeed, it stung a lot.

When Luke closed his eyes, Chaos muttered something that sounded nothing like Ancient Greek. It sounded, older. Even older than the language Briares used when Luke met him a few years ago.

"I don't feel-" Luke felt a very hot and searing pain in his heart. He doubled over. When he opened his eyes, his whole body was sweating. He screamed in agony as he felt some unfamiliar power coursed through his veins.

"You can make it, Luke." Chaos said. That did little to help. The pain kept on getting more and more painful. Luke screamed again as he clutched his heart.

Come on Luke, you can do this. Luke thought to himself.

The pain continued for several more minutes before it ended, leaving Luke sweating heavily and panting. His body ached and felt sore like it had been dipped in the River Styx when it was boiling.

"Congratulations, Luke. You managed to survive the fusion. How was it?" Chaos asked. Luke rolled his eyes.

"It was fun. You should try it sometimes." Luke grumbled. Chaos laughed.

"I will send you to New York."

"At least give me some rest." Luke whined tiredly.

"You will be able to rest at where I will teleport you." Chaos said. She waved her hand and Luke reappeared in a familiar cabin that he used to call home. The soft bed was inviting him to sleep. He managed to open his eyes just a little bit to see a centaur that he had called a teacher.

"Luke!" Chiron cried out before he fell unconscious.

Luke's POV (present time)

"Luke!" Someone was shaking him awake. Luke eyes shot open and saw a pair of grey eyes staring at him. "Come on, wake up."

"Annabeth, let me sleep . . ." Luke whined.

"This isn't the time for games, Luke. Percy's in danger and we need to prepare for our journey to Epirus." Annabeth urged. She was right. They have to save Percy because he's the only one who could stop them. Chaos had told him that she needed two breeds of half human and half angel and demon. If Luke was half angel, then he could only guess that Percy will be the man who will be the half demon. He wasn't sure, but he did sense a strange power coming from Percy.

"Yeah, right. Let me just wash my face." Luke said.

Percy's POV (more or less)

Percy felt his consciousness leaving the body and went straight to the number two place on his Top Ten Places That Percy Hated list. You guessed it, Tartarus. His number one would be in the area around Thalia when she's extremely mad. Emphasis on extremely.

Percy felt himself being pulled to Tartarus. He didn't feel solid, if that made sense. Percy recognized the familiar sight of red hazy clouds and barren wastelands beneath him. He noticed the River of Fire flowing down for another few miles before dropping down to a chasm. Percy knew this was the veiled version of Tartarus, the version that could keep his sanity from losing. He had seen the real version and he didn't like it one bit. The darker version of Tartarus is a lot scarier than what he actually saw. Even the very memory of it was giving Percy the shivers.

Percy didn't crash down to Tartarus. He simply levitated a few feet from the surface. The air was acidic and made his eyes stung like he used to remember. Several monsters crawled around him, but they ignored him as if he was just another damned ghost sentenced to Tartarus. That was when Percy noticed Nyx standing a few feet away from him.

"Hello, Percy." She said with an evil grin.

"What do you want?" Percy hissed. Even in soul form he was able to sound threatening.

"Oh, nothing. I just want to make Olympus as miserable as possible before the war starts." Nyx said. Sure enough, Nyx lunged with incredible speed and somehow got a grip on Percy, even though he was in soul form. Nyx managed to pin him to the ground with one knee on his chest. Percy tried to struggle, but he was powerless. "It's useless, Percy. You can't fight me, not in this form at least." Nyx said.

"What are you doing?" Percy choked out.

"Making sure the gods and your friends are in the most horrible condition they could be in when they went to war." Nyx took out a vial of white liquid that Percy recognized too well.

"No, don't!" Percy yelled before Nyx poured the rest of the liquid down his throat.

Artemis! Percy yelled mentally before his surrounding went black.

(Uh, Pertemis fans, if you don't want to be disappointed, please don't read this part and skip to the A/N)

Alia's POV

Everyone was in the throne room awaiting further plans from Athena except for Liz who was taking care of her father. She and Annabeth had been elected to be in charge of managing further preparations for the incoming war. They have mustered every demigod, nature spirits, friendly titans and monsters. They were training everyone as best as they could.

"-for the nature spirits, got that?" Athena finished. Everyone nodded. Then, two flashes erupted in the throne room and they didn't believe what they saw. Just then, Liz burst into the throne room "Percy's gone!" When she saw the two people, her jaw dropped. She and Artemis almost cried.

"Percy, what is this?" Thalia asked, her voice filled with anger.

In front of them Nyx stood with a wide evil grin on her face. She had her arms around the least expected person that Alia had hoped to see. Percy stood besides her, wearing dark robe and had a weird expression on his face. Confusion, maybe.

"Hello guys, how are you?" Nyx said.

"You bitch!" Artemis sprang from her throne and tried to decapitate her, but Annabeth pulled her down. "Don't stop me!" Annabeth whispered something in her ear that made Artemis relax, but didn't calm down. "What are you doing with him?"

"I'm here to tell you that Percy and I are husband and wife." Nyx said. "Isn't that true, husband?" Nyx turned towards Percy. Percy frowned, as if he couldn't believe what Nyx was saying, but he nodded with a huge smile.

"That's bullshit. Percy won't betray anyone." Thalia said.

"Don't believe me? Watch." Nyx said. What Alia saw next made her want to slit that bitch's throat. Nyx wrapped her arms around Percy and leaned forward. Percy wrapped his arms around her waist and leaned in. When their lips met, Artemis gasped.

"No, no, Percy! This is me! Your wife! Percy!" Artemis cried out. Percy pulled away from the kiss. His sea green and crimson red eyes didn't show any emotion.

"I don't have a wife. I've been married to Nyx since the First Age." Percy said.

"That's true my dear. As you see, Percy is now with me and will be fighting against you." Nyx said. Then, she kissed Percy again. Every time their skin made contact, it hurts Artemis more and more.

"What kind of spell did you put on him?" Michael roared as shadows started to gather around him.

"I didn't use any spell. I just, ah, made him drink something." Nyx said mischievously.

"Bring him back!" Al and Liz yelled.

"No, no, no, children. Percy is no longer your father. He's my husband." Nyx said. Then, she got a grey blast of energy to the face, a splash of icy cold water, a few flaming and exploding arrows, a silver beam of energy, a massive thunderbolt and spears woven out of shadows all at the same time. Nyx flew backwards and slammed onto the wall. Percy had a worried look on his face and hurried towards her.

"How dare you attack my wife?!" Percy roared. Artemis took a step forward.

"Please, Percy, can't you remember me?" Artemis pleaded as tears streamed out of her eyes.

At first, Percy stared at her silvery eyes. His face scowled. When Alia thought Percy was about to gain his memory back, he swung his hand and slapped Artemis hard on the face. The sound of the slap was heard throughout the throne room.

"Mom!" Liz and Al hurried to their mother's side. Everyone couldn't believe what they just saw. Percy would never do that. Something was definitely wrong. Artemis cried as she lied on the floor with her children besides her.

"Dad, it's us. Can't you remember?" Al pleaded. Percy pushed him away.

"Shut up! I have no relations with you! I don't even know any of you!" Percy yelled out. That wasn't just meant for them, but it was meant for everyone. "If any of you lay a finger on my wife again, you will face my wrath." Percy warned.

"Percy," A voice called. Percy turned around and tried to strike in a downward cleave with his hand, but it was met with another hand. A blonde man stood between him and his family. Luke had moved so fast that Alia didn't even see him.

"What do you want?" Percy hissed.

"You know this isn't right. Come on, come back to us." Luke said seriously, but pleading as well.

"I told you guys to shut up!" Percy roared. A black aura surrounded him and exploded, surprising everyone even Nyx who was back on her feet. Alia never felt anything like that. His power was intense and scary.

But then, something else surprised them. The explosion of black aura was countered by a white aura, which came from Luke. The aura battled for a moment as Luke and Percy had a stare down. Then, everything went back to normal as the auras died down. Luke and Percy kept glaring at each other. "We will be enemies on the battlefield, Luke Castellan. I will defeat you, as I defeated you during the Titan War."

"You do remember." Luke said. Alia didn't understand what he meant, but it worked. Percy frowned.

"I-I mean . . ." That was when Nyx decided it was the best time to interfere.

"We will return, Olympians. One way or another, we will destroy you!" Nyx hissed as both of them flashed away. Artemis cried as she placed her hand on the cheek where Percy had slapped her. Alia rushed to her side.

"Don't worry, we can get him back." Luke said.

"He doesn't remember me anymore . . ." Artemis said miserably.

"He does, Artemis. We only need to trigger the memory inside him." Luke said.

Everyone looked at him expectantly. "What do you mean?" Annabeth asked.

"My guess is, Nyx made Percy touch or drink water from the River Lethe, and made him think that they are husband and wife." Luke explained.

A/N: I don't think I want to say much in this part, as most of you are probably already on their way to my bunker armed with bazookas. So, leave a review if you like or hate it, like I said, a review always helps. Until then, take care.

Bunker time ….
