Chapter One

All Things Young and Twins

Harry had been sure things couldn't get any weirder than the last year. Demigods, gods, goddess, and ancient Greek and Egyptian monsters attacking one's school could really put a damper in their summer plans. He had hoped he would meet Percy Jackson and Company again, for now he had more pressing things to worry about. Like how to kill Voldemort without getting turned into a Harry Disaster. It seemed the smell of the demigods had stuck around Hogwarts and Grimmauld Place as well, because they were having an influx of snake-skinned and triple-headed people moving into the area.

What was life without a little adventure? Seriously though, things were getting annoying.

First the Headmaster had shown up in the middle of the night with the girl, who was so hyper she never stopped moving for more than a few minutes and had a snide attitude that gave Snape's sarcasm a run for his galleons. Then Dumbledore had the nerve to say some crazy lady had shown up and shown him a vision of the future, in which the Headmaster was dead, Sirius was dead, Remus Lupin was dead, and a plethora of other cool people were dead. Not to mention, the entire world was dead and it had been turned into a barren wasteland with monsters crawling on every square inch.

Wonderful. Why wasn't Harry surprised?

So what did Dumbledore do about it? He called an emergency meeting to discuss new approaches to the war. How there were going now wasn't going to work, so they needed to shake things up a bit. Not his words exactly (the girl's, actually. She was American of all things!) but that was the gist. Awesome! Harry had thought. Finally the old Professor was giving up on his ways of beating around the bush. Then the words 'time travel' had come out of Dumbledore's mouth, and then Harry's thoughts had quickly gone to schist!

At least he wasn't the only one who thought Dumbledore was just a little insane. McGonagall and Sirius shared his sentiment, as much as they respected and cared for the old man. The Transfiguration teacher stood by the door, watching Dumbledore with unmasked shock. To see his stern, iron willed Professor watching the Headmaster with a wide, gaping mouth was somewhat disconcerting.

So maybe his cynical mood was helped a bit from the girl. The girl, who had yet to introduce herself. So far all she'd said was 'cat'. That couldn't have been her name? Who named their kid 'cat? Unless they really, really liked cats . . . He cast critical green eyes on her. He had never seen anyone dress like her before.

She had short, shaggy, heavily streaked blonde hair. Her large blue-gray-green eyes held a predatory glint in them that made Harry want to yell "take cover!" whenever she walked near someone. Her skin was pale and she had deep bags under her eyes that told of many sleepless nights. She wasn't much shorter than Harry, but he was short, so that made her short as well. Besides her rather sallow facial expression, it was her get-up that was weird.

She wore a black leather jacket, a tank-top, and a loaded gun holster on each side. Her jeans were ripped, from what looked suspiciously like claw marks, and black, with daggers strapped to her thighs. He could just see the glint of a knife hilt sticking out of the top of her thick leather combat boots. She didn't specify what she had on her, but them threateningly there was over a dozen weapons on her person. Not including the sword strapped to her back.

The girl was a walking, talking weapon arsenal. Harry knew where to go if he needed a dagger. Or a hand gun, because she had at least five of those, and treated them like they were her 'precious'.

There was a tattoo on the top of her hand, which went up into her jacket sleeve. It was a runic symbol of some kind, but Harry didn't know what it was. Neither did Hermione, who had asked the girl about it several times. It was an eye, with a tear falling from the corner. Lines like wind currents wrapped around the eye and went up into her jacket.

". . . you think, Harry?" Dumbledore's voice broke through Harry's thoughts.

"Uh, what, professor?" He asked, feeling his neck burn.

Three of the other seven kids snickered. The seven heroes, being Percy, Annabeth, Leo, Piper, Jason, Frank and Hazel were joining them with Nico. Harry remembered them from the year before when they had helped him fight off Voldemort during the Battle of the Department of Mysteries. They had also gone to Hogwarts to get to know the wizards and fight off Setne and their enemy, Apophis. It had turned into a full force battle in place called Deos-Natale, or the Birthplace of the Gods.

They had volunteered to help with this mission, even though they were leaving behind everyone. It was a huge sacrifice, but they agreed that the fate of the world was a bigger price to pay. The lives of every human being in the world rested on their shoulders, and they weren't about the let that ball drop. The whole seven had drawn back together again to help Harry and the other fight their enemy in a different way.

The other two kids who hadn't gone to Hogwarts, Frank Zhang and Hazel Levesque, had introduced themselves earlier as the son of Mars and daughter of Pluto. Harry didn't know them farther than the small talk they had engaged in when they first walked in the room, but seemed like pretty nice people. They stuck by each others sides, so Harry thought they were a couple or something.

Dumbledore smiled, and waved his wand around the room.

Silencing wards, Hermione mouthed at Harry. Good thing he had a genius on hand, because he hadn't had a clue what Dumbledore was doing. The Headmaster stopped and stowed away his wand.

"I think there are a few things that we need to discuss. I assure you – all of you," he stressed, "that everyone in this room is completely trustworthy. Yes, Mr. Weasley," Dumbledore smiled, interrupting Ron's question, "even Mr. Malfoy, as rude as he might have been in the past. I think it's time for the real explanations. Miss Chase. Do you mind?"

Annabeth nodded, stepping forward. She clasped her hands in front of her, like a professor about to give a lecture. Hermione sensed this, and leaned forward to listen intently. Harry was sure if she had parchment and a quill she'd take notes.

"I'm sure you've heard of the ancient Greek myths?" Annabeth asked.

Hermione nodded, but McGonagall shook her head. Harry was surprised that McGonagall had never heard of the Greek myths before, but he was even more surprised that Draco was nodding his head with Harry, Hermione and Ron.

Draco Malfoy, pureblood supreme, learned about muggle mythology? Why not? Pretty soon he'd be breaking out of the hippie bandanas and singing peace and love and sticking flowers in Weapon Girl's guns.

Annabeth sighed. "Okay. Well, the Greeks were an ancient muggle civilization that lived in, obviously, Greece. They had legends and stories about gods and monsters. In these legends, the gods would often come down and become . . . involved with the mortals."

"That's for sure," Draco muttered.

"Shut up, ferret," Jason said, but his twitching lips betrayed his humor.

Annabeth rolled her eyes. "Anyways, the result of that was -"

"Little demigod kiddies running around and fighting monsters for the gods 'cause they're too lazy to do anything themselves." Leo grinned, throwing a pinwheel in the air, which somehow stayed aloft.

Harry figured it was something to do with Leo being a son of Hephaestus.

A lop-sided grin lit up Percy's face. "That's about sums it up."

Annabeth sighed. "In case you're wondering why I even bring this up – who am I kidding, of course that's what you're thinking – the legends are real."

There was a collective silence, McGonagall and Sirius stared at her in shock. Sirius finally coughed, diffusing the silence. "Just so you know, you missed the appropriate time to shout: not!"

Weapon Girl, who had yet to introduce herself, still, groaned loudly. "Oh would you quit beating around the bush? The gods are real, the monsters are real, they mess around with mortals and have kids. These kids are demigods. Over half of the people in this room are demigods."

McGonagall and Hermione frowned at the same time. Hermione opened her mouth, and Harry mentally prepared himself for a long discussion. "There are sixteen people in this room. Eight of them are demigods, and eight are us wizards. That would mean that one or more of us are demigods. That's if anything you're saying is true, of course."

Annabeth's gray eyes bored into Hermione, and Harry half expected the smartest witch of the century to go up in flames. However, it wasn't Annabeth who said the scathing remark. Malfoy pushed himself from his leaning post and joined the new kids on their side of the room. His eyes were narrowed, and standing next to Annabeth there was a certain . . . similarity, in their gray eyes. They had the same stormy intensity.

For a second, Harry thought . . . but, no. That was ridiculous.

"Granger," Malfoy said in a patronizing tone, "that's because over half of the people in this room are children of the gods. Dumbledore is the son of Hecate, goddess of magic. Sirius never knew, but he's the son of Hermes. And me -" he smiled, a real smile, not a smirk, "I'm the son of Athena, goddess of wisdom and battle strategy."

Hermione snorted. "Tell that to your marks."

A shadow passed across Malfoy's face. He snarled, "Do. Not. Insult. My intelligence."

"I'm not insulting your intelligence," Hermione said. Harry sensed a big but in there somewhere. He was right. "But there is much intelligence to insult."

Annabeth's mouth twitched with suppressed humor. "Hermione," she said calmly,"don't insult a child of Athena's intelligence, unless you want to die. And I'm the daughter of Athena, making me his sister. Don't insult my little brother."

Malfoy gagged. "What have I said about calling me your little brother?"

Percy, who had draped his arm around Annabeth's shoulders again, smirked sarcastically. "A thousand and one times, ferret. Funny thing, it never seems too bother her too much."

McGonagall looked like she was trying to swallow a hair ball. "If you're all children of the . . . gods," she seemed to force the word out as if it gave her physical pain, "who are you godly parents?"

Percy jumped forward, mock saluting. "Percy Jackson, son of Poseidon, god of sea. And here's a demonstration to prove we're right." He opened his hand, and water came flying from the door. There was a muffled shout from the person who had lost their water.

The water floated in a steady stream to Percy's outstretched hand. He closed his hand into a fist, and the water circled around it like rings on a planet. "Neptune has rings, doesn't it?" He asked Annabeth curiously.

She smiled and shook her head. "Yes, Seaweed Brain."

Leo waved his hand, which burst into flames.

Professor McGonagall began to look a little faint. Dumbledore smiled gently. "I think, for the sakes of the professors, you should tell them your parentage."

An impish grin completed the elvish look on Leo's face. "I'm the son of Hephaestus, god of blacksmiths and fire. No, not all children of Hephaestus have this power. It's just a sign from above of how incredibly awesome I really am."

Piper rolled her eyes, as if she was used to Leo's antics. "I'm the daughter of Aphrodite, goddess of love. And no, I am not a brainless bimbo."

"Lighten up, beauty queen," Leo said. "Not all of us have super-awesome face-reading power that help us know what the other is thinking. We're just lowly mortals. Grant us mercy!"

The eyes of the room turned to Nico, who glowered darkly. "Son of Hades, god of death and lord of the Underworld."

Frank closed his eyes with concentration, and then he shape-shifted into a huge grizzly bear, which sent everyone reeling back. He changed back and smiled, "Frank Zhang, son of Mars, war god."

Hazel introduced herself as, "Hazel Levesque, daughter of Pluto, god of the underworld and riches. Yeah, I know. Roman aspect. Try not to think about it too much."

Jason shook his head with a small laugh. "Guess that leaves me. I'm the son of Jupiter, lord of the sky and king of the gods."

McGonagall opened her mouth, but Jason cut her off. "Don't ask. I'm the son of Roman aspect of Zeus. It's a headache and a half, I know."

She closed her mouth, looking somewhat miffed. Finally Harry couldn't take it anymore. "Who are you?" He blurted, glaring at Weapon Girl in the corner. She hadn't moved an inch, and just stood there, watching diligently.

Percy looked at her, and frowned. "Oh, her name is -"

"Katelle Sparrow," she snapped in a clipped Irish accent. "Daughter of an evil Titan."

Harry felt immensely confused, but Hermione didn't. She looked apprehensive. "Is your dad, by any chance . . . Kronos?"

"Yeah." Katelle said in the same clipped tone. "Got a problem?"

"No, not at all." Hermione said quickly. She threw Harry a glance. We'll talk about this later.

Dumbledore took the silence as a chance to talk again. "Miss Sparrow here is our key to sending you into the past. You see, Kronos was the Titan of time. With the help of a few spells, a particularly powerful time-turner, and Miss Sparrow, we'll have you sent back in time fifty years."

Shouts of outrage echoed around the room.

"You shouldn't meddle with time! Bad things happen!" Hermione.

"You old loon!" Malfoy.

"Sounds fun!" Sirius.

Dumbledore raised his hands, and everyone fell quiet again. "We haven't got much choice, I'm afraid. The future is a grim one, at best. Many good people will die, who shouldn't have to die."

Katelle shrugged her shoulders. She had pulled an apple out of her the pack – which looked like termites holding hands – and started to slice bite-sized chunks of it with a silver knife. "I'm willing. I've looked at the power of this spell, it will completely drain me. I'll have very little, if any, control over time. My limited control over fire might stay, and light, but besides for that I'll be rid of a large curse."

"Since when was control over time a curse?" Sirius grumbled.

"And how would we get back?" Hermione put in."

"It's not the power that's a curse, it's the message behind it; the legacy of who had it before me. I don't want that legacy." Katelle explained. "And we'll have to find our way back the hard way. You guys were never promised this would be easy."

Harry scowled. "What is the plan? The exactly, whole plan. We're going back in time. Great! I'll do it to destroy Voldemort. But what do we do once we're there? "Find our way back"? What does that mean?"

Dumbledore sighed heavily, looking older than ever. "I cannot allow you to do this on your own, Harry. I'm afraid this mission is of absolute importance and is necessary to the livelihoods of many hundred people. I will be accompanying you into the past, and joining you at Hogwarts."

Dumbledore, join them?

Harry was surprised, to say the least. Dumbledore had never physically helped in a quest. He would leave cryptic advice, and messages for him to decode, but never actually get his hands dirty. Now he would be going back in time with them. He supposed it made sense, although there was only one thing, one little – humongous – flaw in the plan that sent stabs of fear into Harry's gut.

"Professor," he said slowly. "Last time we traveled back in time, we changed nothing. During third year, all we did was complete what happened originally and answer questions."

"I can answer that question," Annabeth said. "You see, from what I've heard, you guys weren't outright trying to change time. You weren't trying to be seen, or do anything large. When you change time, it has to be big. You have to dive straight in a really mess things up. It's not like the world's going to blow up because of it. The time line with straighten out, how you made it."

The only people in the room who looked excited were Sirius, Leo and Malfoy, to Harry's surprise. He supposed it was the Slytherin ambitiousness that was getting to him. Even if it was ambition to completely change the course of history. Sirius clapped his hands, making few people jump. "So, when are we leaving?"

Dumbledore smiled serenely at Harry's godfather's enthusiasm. "As soon as Miss Sparrow is ready, and Professor Snape brings the de-aging potions."

The smile was whipped off of the three trouble-maker's faces. "De-aging?" They cried in unison.

Annabeth smirked at Percy's shocked expression. "Yup. I get to be taller than you again, Percy."

"Don't remind me," he mumbled.

"Who cares about height!" Sirius exclaimed, silvery excitement in his voice. "We're going to see an eleven year old Albus Dumbledore!"

"Don't forget Severus," Dumbledore said.

"What?"

"That's right," a voice drawled from the door, "although knowing your level of intelligence the Headmaster could have told you five times and you would have forgotten."

Professor Snape walked in with a flourish of his robes and sharp nod at Nico, who waved half-heartedly. "Hey Sev."

Harry gave a start of surprise. Why was Nico talking to Snape like he was close to him or something? Snape sneered, "for you of low intelligence, I am a legacy of Hades as well, making Nico my half brother."

You poor thing, everyone in the room thought at the same time, with the exception of Malfoy and Dumbledore.

"You're related to Snivellous?" Sirius asked flatly. "You poor thing."

Well, Sirius said it out loud.

"Bloody Gryffindor," Snape sneered.

Nico smirked, and the ring on his finger suddenly grew into a long, black sword. The shadows in the room darkened, bending and twisting as if they were reaching out for the blade and the son of Hades. Nico held the sword up, his smirk widening. "Stygian Iron. Forged from the River Styx. You don't want to be cut by this sword."

Katelle rolled her eyes, making herself known again. "Let's just go, okay? The longer we wait, the harder it will get for me to control it. We need to go back roughly fifty eight years, to 1938. That was Voldeshort's first year, right?"

Dumbledore nodded gravely. "Because of how his birthday fell, he had to wait nearly an extra year to attend Hogwarts."

"Like me," Hermione and Katelle said at the same time.

Katelle shrugged, and smiled for the first time. "I was born January seventh."

The twinkle in Dumbledore's eyes seemed to die a little at that. "You might find Tom . . . fascinated with that number."

Katelle shrugged. "Whatever. I wouldn't care he wanted to dress up like an Aztec and do a dance number. Who is in? If you aren't willing to go back fifty-some years, raise your hand."

No one raised their hand. Katelle went on. "Well, McGonagall can't come. Professor, you were in your second year when Riddle started his first, so you'll be there. I'm sure it would raise a few thousand eyebrows to see her twin there. Professor Snape, you're clear to go. There's no Snivellouses back in 1938."

Sirius smirked triumphantly. "And we can all become Animagi once we arrive at Hogwarts so we can keep an eye on Riddleikens."

Dumbledore took his wand from his sleeve again. "Severus, if you would hand out the potions?"

Professor Snape set to giving everyone their potions, nearly throwing the brackish looking liquid-filled vial at Sirius when he passed him. He sneered at Harry, but muttered, "I'm doing this for Lily," and gave it to him. There was one left in his hand after he was done, and Harry realized Snape actually planned on coming with them. Harry wondered what Snape looked like as a ten year old. That made things more interesting.

"Eleven year old Albus," Sirius cackled as he held up his dark brown colored potion.

"Bottoms up!" Leo called, and tipped his potion into his mouth. He made a face and gagged, doubling over and pressing his hands into his stomach. "Oooh, not cool. Tabasco sauce and motor oil. Where's Festus when you need him?"

Percy followed, along with Dumbledore, Jason, Piper, Annabeth, Nico, Sirius, Snape, Hermione, Ron, Harry, and last Malfoy. Clearly the ferret was waiting to make sure no one died, and then he would drink the potion.

Systematically, everyone doubled over as if the air had been punched from their stomachs. Harry groaned, feeling his body ache painfully. His bones made snapping and popping noises and he shrunk. His clothes became as baggy as Dudley's had when he was eleven years old, before he discovered he was a wizard. His hands became smaller and a little pudgier, and his face was smoother and youthful.

He looked around the room and laughed.

Percy was as scrawny as Harry, which made him wonder if he was malnourished as a child, and his over-sized orange T-shirt made him look even smaller. Annabeth was cute, with her blonde hair even curlier and almost as bushy as Hermione's, coupled with huge stormy gray eyes. Leo looked more like one of Father Christmas's workshop elves rather than a Lord of the Rings elf. Jason was still muscular, and his hair was shorter cropped. His eyes looked a little more guarded, as if being eleven had brought back memories.

Nico groaned and covered his face. His dark Italian olive complexion had come back, and his was healthier looking, hanging in slightly shorter curls. The shadows thickened in front of him, and a deck of cards and several metal figurines appeared in front of him. Nico covered his face again and moaned, "dad, really? Mythomagic?" His voice was higher pitched, and softer.

Percy grinned. "You're never too old for games."

Then Harry saw Snape and he laughed again. The Potions Master was skinny little kid with long hair black hair hanging in his face, maybe a little less greasy, and large black eyes. His nose wasn't quite so big, and he wasn't nearly as tall as he was before. Next to him, Sirius wore a grin that Harry was sure Snape hated. Sirius's face had lost the hollowness from Azkaban, and seemed to glow with cheerful mischief.

"All hail," Sirius said with mock graveness, "the new Marauder's era."

McGonagall's eyes widened in horror. "My younger self is going to be going to school with you!"

Sirius turned his evil smile from Snape to McGonagall. "Don't worry, Minerva, dear. I'll make sure to seduce your younger, more impressionable self."

"Sirius Black, don't you dare!" McGonagall shouted, pulling her wand.

Sirius yelped, covering his face behind his hands and peeking through his fingers. "You would hurt a helpless, innocent child would you, Professor?"

"Oh, would we get this over with?" Snapped a furious Irish accent from the corner.

That was it. The final straw. Harry exploded into laughter, doubling over as tears streamed down his face. Katelle's tough-girl act would be futile. She was adorable. Her large blue-green-gray eyes were even larger, she had a round, angelically innocent face, with long straight locks of golden blonde hair. Her skin was pale, she had a small frame with high and girlish voice. She was the picture of innocence.

She glowered darkly at Harry, or at least tried to. It made it look like she was pouting. Sirius joined Harry's laughter, although Harry wondered if his godfather even knew what he was laughing at. He asked him.

"Nope," Sirius laughed. "But laughing is fun!"

Katelle pouted. She did it well. "He's laughing at me," she whined.

Leo looked at her, and his eyes shone with poorly concealed amusement. "Holy mother! That's how the most terrifying girl in the world looked like at eleven?"

Piper, who looked like how Harry had imagined Pocahontas, smiled. "Be nice, Repair Boy."

Katelle ignored them, and glared – or tried to – at the smiling Headmaster. "What next?"

"Names and family," Dumbledore said with a smile.

Harry blinked in shock at the child Headmaster. He had shoulder-length wavy dark auburn hair, an open, cheerful face with ever twinkling eyes. His eyes seemed brighter and clearer than before, and like he was permanently laughing inside. He was about the same height as Harry, which surprised him, was as slim as Harry. His long robes dwarfed him humorously, pooling on the floor at his feet like a silvery-blue puddle.

"I have decided that Harry, Severus and I shall be brothers in this new – or shall I say old? - time." Dumbledore went on. "Harry may still be Harry, and I will be Albus, and Severus will be Severus, but we will have the last name 'Evans'. Any objections?"

"A thousand and one, Headmaster," came Snape's new, high-pitched innocent sounding voice.

"None, sir!" Harry piped in. I get to be Dumbledore's brother? He was cheering inside. "But sir, we look nothing alike!"

Dumbledore pulled several more potions from various pockets. "Never underestimate an old man, Harry. Hermione, Piper, how would you two like to become sisters?"

The two girls gaped, but shrugged.

"I am doing this so it doesn't look like there are over double the usual children going to Hogwarts. There will simply be several twins and a set of triplets." Dumbledore explained.

He gave Hermione and Piper potions, which they drank. They didn't change much, but Hermione's skin and hair became a little darker, her eyes looked like a mix of green, blue and brown – like Piper's – and her hair wasn't as bushy. Piper looked no different, although they shared similar facial features. They could pass easily as twins. They decided to keep Piper's last name McLean, because Piper Granger had too many -ers in it.

Annabeth and Draco already looked enough alike because of their godly mother. Draco, albeit reluctantly, became Draco Chase, the half-blood. Nico and Leo refused to let go of their last names, so they became adopted brothers instead of taking a potion.

Sirius had mocked-mope about having no brother or sister, so Jason became his twin. Sirius benefited the most, his hair becoming more uniform in waves, and his face turned more Roman-like. Jason barely changed, but his hair grew a few inches and became wavy.

Dumbledore's eyes darkened into a more ocean blue, rather than a horizon blue, and his hair turned deepened a shade, so it was almost blood red. Harry's hair turned a bit redder, and but his eyes and skin stayed the same. Snape's hair – thank Merlin – was no longer greasy, and became a much lighter shade of blackish-red. His eyes turned into a deep emerald, and grew larger. Most of all, his nose was no longer overly large and crooked.

"Well, Snivellous," Sirius grinned. "Looks like you might not have such a hard time with the ladies."

Younger age hadn't hampered Snape's ability to sneer. "We're going to the past to stop the Dark Lord, not party like children."

Leo coughed. "We are children."

"Amen." Sirius said.

"Wow," Piper and Hermione said together.

"Did you practice that?" Harry, Dumbledore – Albus – and Severus said in unison.

Dumbledore sighed. "Drawback of the potion, I suppose. It should, hopefully, wear off."

Harry leaned over and muttered to Hermione, who Ron suddenly couldn't stop looking at even though she was only eleven, "if I start wearing purple robes and giving out lemon drops, give me a good kick, yes?"

"Agreed," she whispered back with a giggle.

A/N:

Chapter one! Of. A. Lot. More.

Sorry this is pretty much a whole chapter of nothing but face-changing and joking around. There's a ton of characters, I know, but that will become important later on, so don't get discouraged if it seems like some of them are being ignored.

If you've just stumbled across this for the first time, then go read the first story! It's called The Rise of Magic. A pretty easy, cliche title to spot on my profile page. Just ignore the blather about stories I'll probably never get around to doing. Except for the Fablehaven one maybe.

In case there are any people out there who have been SO desperate for scy-fy that they recognize some of the further plot as if goes along, this was inspired by Primeval, BBC series that I love. Yes, I was that desperate for a dinosaur time-traveling show. Does Dr. Who have any dinosaurs in it? Because if it does, I am addicted.

I'll post the next chapter in three-to-fourish days, so until then!

DISCLAIMER (btw, I am not posting this in every. single. chapter. I'll forget.): I do not own, Harry Potter, Percy Jackson, or any of Primeval's stuff that any legal blood-sucking tick of a nuisance might recognize. So stuff it, lawyer.
