"BLEEDING HOGMONKEYS!"

Aang swerved, narrowly avoiding the pair in green that had invaded his airspace.

"Hey, poser! Come on up!" the boy yelled, freefalling past the Avatar.

The girl laughed, following the boy, who could only be her brother, in his steep dive.

It took a moment for Aang to snap out of his shock, angling his flier downwards.

The pair had appeared out of nowhere, without anything even remotely resembling an Air Nomad Flying Staff.

That only left spirits as the explanation. Powerful ones, if they were here in the real world.

He landed in a clearing, where the two siblings immediately latched on to his shoulders. "Come on. Percy wants to see you."

-------------
Percy snickered as he remembered the twelve-year-old Avatar's expression as he took in the Guardian camp.

They had only been there to give Aang some advice, but Percy couldn't say no to Leo kidnapping a firebender short term (Thalia and Clarrisse helped) to learn some moves.

But that was a few worlds ago. This one was much more interesting.

Annabeth had theorized that Chaos had, for lack of a better phrase, 'shanghai'ed the plot ' in this world, using his rather subtle and liberal manipulations of the Mist to give the Guardians a good reason to stick around.

The Guardians watched as Harry and Dumbledore walked through the woods, completely oblivious to the fact that they were surrounded.

The demigod's hoods were up, masks on. Even Nico and Thalia were sporting their own custom made black and silver cloaks.

Their masks were the same however, the only difference being that Thalia's had a symbol of Artemis on its forehead, antlers with a crescent moon, and Nico's had a strange triangle, circle, line thing Jazz had insisted on.

The daughter of Hecate (having been horrified no one had bothered to read or watch the series, despite protests that not dying took up a lot of time) had forced them all to watch the condensed musical, so they all thankfully had an idea of what was going on.

The only reason they had time to do so was because they watched it in the land between the rain drops, where time didn't really exist, only space.

On Annabeth's signal, Percy removed his mask and hood, features shifting, hair shortening and his eyes becoming more emerald than seagreen.

Annabeth sliced her hand through the air. Now!

Thalia and Percy lunged, the former grabbing Harry and bringing him to Mira, who with a single movement stole away his sound.

Dumbledore turned to face Percy, who filled the space Harry had stood moments before. "Everything alright, my boy?" he asked, seemingly finding nothing out of the ordinary with 'Harry's' features.

Percy nodded, looking down and subtly readjusting the glasses he had made appear. "Sorry, sir, " he said, "I tripped over a root." He tried to appear suitably embarrassed, if only as an excuse not to look Dumbledore in the eye. Jazz had been very clear on that particular point. He'd rather not have the 'leader of the light' getting his brain fried if he tried rifling through the memories of a god.

Dumbledore nodded in understanding, his surface thoughts refocussing on his own footsteps and trying to ignore the disappointment he felt. Not suspicous, then. Percy resisted the urge to smile at the memory of the evil laugh Jazz had given when she told him of the difference in the pair's ability. Percy not needing eye contact would surely, should he learn of this fact, make the headmaster's ego take a hit.

"We are almost clear of the monitoring ward, " said Dumbledore. "I'm sorry for bringing you out here, my boy. Such a shame the ritual failed."

"Pardon me for asking, sir, " Percy began, beyond thankful for the Mist disguising his New York accent, "But what do you think went wrong?"

"The circle was supposed to summon a heroic leader to help aid the war effort. It seems none fit the criteria."

There was that ego again. Had Dumbledore just assumed Percy would help? Did he not even think about how the 'heroic leader' might have felt, being yanked from his world and forced into a battle not his own?

Talk about a god complex. Having met gods far more than he wished to, Percy knew all about those. He was almost impressed by the mortal's arrogance, but he'd had a few too many meetings with various ancients for that.

He would have said this out loud if not for five decades of Council meetings, which had shown him some battles you just need to let go.

Only thing Ares ever taught him.

Dumbledore held out his arm to Percy. Feeling a bit off, since he was about six inches shorter than he normally was, Percy took it.

The sensation of apparating was horrible, just like Jazz had warned. It was only because of the rather sadistic fall drills Thalia had made the entire guard run for hours in the land between the raindrops that let him land on his feet.

He felt like he just spun through the Shadowlands, but he was fine. He wouldn't let a little matter like bastardized shadow travel faze him.

His first impression of Grimauld place was Dumbledore's dirty looking, bright glowing bubble around number twelve.

That must be the Felix Charm. Percy thought.

He glanced at the dozens of wards. The flowing script swirled around the house, entwining with the stone and wood and making the beginning of a headache pulse at the back of his head. He looked away quickly, the wards fading till they were barely visible.

Dumbledore gestured for Percy to enter. Stepping inside, Percy glanced at the other's mind to figure out what he was expected to do and headed up the stairs. "Good night," he said, nodding to Dumbledore.

"Good night, Harry."

Percy disappeared into the hallway to his right, listening for the sounds of the teenage boy Jazz had told him about.

He looked into the open door a few feet down, which revealed a redhead sitting in front of a chessboard.

"Hey, Ron," Percy said, not even having to glance at the names and descriptions written on the inside of his wrist. The musical had been quite memorable, after all.

The redhead looked up as Percy stepped in. "Harry, mate. You look like hell. What did you and Dumbledore do?"

"I'm not exactly sure, but whatever it was didn't work. I'm heading to bed."

"Harry!" another voice said, a girl with frizzy hair appearing. She could only be the Hermione from his notes. "You're back! Tell me everything!"

"And you promised me a game when you got back." The red head glared without any heat behind it.

Harry was a people pleaser, Jazz had said. Percy realized he had no choice but to sit and talk. "Alright. Pawn to D Four."

A good move Annabeth taught him. To control the board gave you room to move. A good strategy, provided you had the manpower to manage it.

Hermione listened as he described what happened: the circle (which he had glanced at on his way to catch up with Dumbledore), the lightning, and the supposed failure.

Meanwhile, he trounced Ron, having played against Annabeth for years. A mortal teenager was nothing.

Percy grinned in victory. "Well, I'm heading to bed," Percy said, frowning at Ron's look. "What?"

"You've never won before," Ron said, seeming slightly stunned.

Percy panicked. "Well, I was listening to the pieces a lot, and I've seen you play so much that I changed it up a bit to match you so it was really just luck and going with the flow," he said quickly. "Red vine?" He held out the twizzler knockoffs he had grabbed from the tent of Requirment.

Ron took one, seemingly appeased.

Hermione nodded, seemingly having decided something. "Hey, Harry?"

"Yeah?" Percy said, grateful for the distraction.

"Can you grab my numerology book downstairs? I'm at the chapter on the use of the Roman lexicon and it's exciting. I'm going to finish it before bed."

"Uh, sure?" Percy said while Ron looked at Hermione like she was insane. Percy wasn't sure why she asked him instead of getting it herself, but Harry was a bit of a doormat according to Jazz, which meant that, at the moment, so was he.

If he had listened as he left the room, he may have heard Hermione dive for Harry's chest, and if he had glanced back he may have seen her pull out a shimmery cloak.

As it was, he didn't see or hear any of this, instead quickly finding the book and heading back up the stairs, hoping none of the other house occupants would try to talk to him.

She smiled and thanked him, and if he had looked in her mind at that moment he would have seen a plan forming as he headed off to bed.

---------------
Hermione threw the cloak over her head as she followed Harry through the hallways, heading towards the Black family library.

He had risen around two in the morning, right when Hermione had been about to give up and head back to her room. He'd stood without making a sound, expertly placing his feet where the wooden floors wouldn't creak, going so far as to hug the walls and railing. She followed after him, wincing as her own footfalls made the stairway creak.

Harry didn't seem to notice, maneuvering his way down to the library. Hermione let out a soft breath, only to pause as Harry stopped moving right as she crossed archway.

"You can come out now, Nico."

Hermione froze, praying that he hadn't caught her. She turned to leave, only to find Harry behind her, hand stretched out. She flinched back, glancing where he had been only moments ago.

"You can't sneak up on me anymore, Neeks. I can sense your death magic from a mile off." His hand reached for the cloak off and he froze as it slid off, revealing her shocked face.

"You're not Nico," he said, sounding offended.

"And you're not Harry," Hermione stated, trying to sound confident as she slipped her wand out of her pocket.

Harry grinned, a mischevious look in his eyes (were they always the color of the sea?) and a sinister slant on his lips. "You caught me. Bravo. Jazz was right to warn me of you."

Hermione leveled her wand at him. "Who are you?"

The imposter shrugged before waving a hand. 'Harry' melted away like water off a ledge. The stranger was taller then before, his skin turning tan and unblemished, his hair growing longer with a single streak of grey behind his ear.

"Remember that summoning ritual? I'll tell you a secret." He leaned in close, completely unafraid of her, and whispered in her ear.

"It didn't fail."

---------
Annabeth facepalmed, eyes on her mirror shield she was using to watch Percy. "We have got to keep him away from Zeus," she muttered.

Thalia looked over from where she was sharpening her spear. "What he do this time?"

"He's being dramatic."

"Nothing a good shock won't fix."

Thunder rumbled.

Annabeth facepalmed.
