Thanks to everyone that reviewed or followed. Also! In this story there might be some small OCs, I hope thats not a problem

The characters belong to Rick Riordan and Cassandra Clare, but the plot, however, belongs to me ;)

Jace slept restelessly and terribly. His dreams were all darkness and horrible monsters. He saw a two headed dog, its mouth open, revealing sharp teeth and frothing spit, a low growl escaping the left head, while the other snapped its jaw at him. Then, as if someone had dipped their hand in a clear pond, the dream rippled and disappeared. He was now sitting on a beach, the muggy air making evident he was somewhere in the southern hemisphere. The moon had bleached the fine, soft sand white, and the dark waves were small and calm, the tide flat. Behind him was dense tropical forests, with palm trees and giant elephant leaves visible. He looked down at himself and noticed that the ankles of his jeans had been rolled up for him, and that he was wearing no shirt. Even without it though, he was still uncomfortably hot and sweaty. He was very aware he was dreaming then, and when he blinked, a girl sat next to him. She was very pretty, with shoulder length silvery blonde hair, the same colour as pearls, and icy blue eyes. She was very close to him, and was wearing a long, satin dress that was blacker than anything he'd ever seen.

"Where am I?" Jace asked. It felt very cliché, but he wouldn't mind knowing.

"No where man has discovered yet" she whispered. Her voice was lulling and soft, making Jace sleepy and calm.

"Who are you?" He questioned, shifting slightly so he could look at her face-on. She smiled gently at him, and raised a hand to his cheek. Jace flinched away from it, her palms icy and cold. She lowered her hand and kept smiling.

"I am Selene" she said, tears welling in her large eyes. Jace didn't know what he'd done to make her cry, and he wished she wouldn't.

"Selene?" He asked sleepily. She looked so familiar, but he couldn't place where or when he'd seen her. "My mom's name was Celine" he said, feeling a bit like a child being put to sleep with a fairytale. Not his childhood, but what childhood bedtime was meant to be like.

"I know" she said sadly "she was very beautiful. As you are, Nephilim". Jace smiled crookedly; glad to be complemented by the nice lady.

"I watched you parents, you know. As I watched your great-great grandfather fall in love, and all of his descendants. But that is not why I am here" she explained, and Jace nodded with his jaw hanging open.

"I need you to help me, and my sister, we have already lost our brother, you know" she said, the tears gone "Jonathan Morgenstern means to destroy both worlds, yours and mine. And I need you to make sure he doesn't. Tomorrow, go to the oracle and ask her for a prophec-"

Jace sat up, gasping. He was sweating like crazy, and the light in the over-crowded cabin had been turned on. Someone had shook him awake. Over twenty kids in their pyjamas were staring down at him from his place on the floor, where he'd been set up with a sleeping bag from Chiron. Yesterday, Chiron had taken Jace for a walk around the camp, trying to convince him he was a demigod. Jace, on the other hand, had shot down every possibility, claiming he was Nephilim, and didn't know what the old centaur was talking about. He'd been sent to this cabin with a sleeping bag and without his belt, where he'd promptly fallen asleep.

"Dude" one kid said, his hair mussed and bags under his eyes "are you okay?"

Jace rubbed his head and nodded, mumbling an apology.

"Are you sure you're alright?" A girl asked, her dark eyes worried.

"Yup, I'm just peachy" Jace sighed, turning around and burying his face in his sleeping bag, wondering if Clary was worried about him yet.

Clary, Isabelle, Jason, Piper and Leo spent the entire night waiting for Percy Jackson to do two things.

One of them, and the most important was for him transform back into a person, and not what was classically a mermaid. He still had a normal face and torso, although his neck had grown gills, and he had webbed hands and a dorsal fin. His tail, on the other hand, was a bright green, and hauling him back to the institute was no easy business. Piper - the pretty girl with the braids - had had to speak to the police several times when they asked what they were doing. She had (very surprisingly) convinced them they'd come back from a dress-up party and Percy had gotten a bit drunk.

The second thing they were waiting for was for him to become more or less sober. He'd been talking about how much he the colour of Clary's hair for a good fifteen minutes, and he almost made Isabelle faint when he started making water float around the room. He was currently laying in the bathtub, his tail hanging a bit over the side, and the water just covering his bellybutton. Jason had fallen asleep awhile ago, passing out on Jace's bed and snoring softly. Piper was leaning up against the tiles of the bathroom wall, absently playing with a feather in her hair. Leo was making impossibly intricate houses out of things he found in the cabinet of Jace's bathroom. Clary was playing pattycake with Isabelle, who's eyelids were drooping, sitting on the floor of the bathroom and waiting.

Percy was humming to himself quietly what seemed like the tune from Happy Days before picking up a bottle of shampoo and a bottle of conditioner and shaking them at eachother.

"A conditioner of the eldest products" he began in a gruff voice, laughing slightly afterwards "shall reach its expiry date against all odds". Then he suddenly burst into a fit of giggles and dropped the bottles in the water, and making Leo jump and knock over his eiffel tower made out of soap.

"Whats so funny Percy?" Piper asked, blinking slowly and tiredly.

"If that prophecy is for this-" he held up the bottle "-that would make me conditioner". He flipped his tail up slightly and smiled at, before resting his head back and sighing. "I miss Annabeth" he said sadly, his lower lip trembling.

"Oh gods" Piper sighed, putting her head in her hands as Percy laughed even harder. He flipped up his tail up and splashed water on Leo, who groaned.

Then, the door of Jace's bedroom burst open and Alec walked in, dragging a kid by his jacket into the room.

"Jace look what I found-" he started.

Jason rolled off the bed in surprise, and Percy waved happily at Alec. Alec let go of the kid and stared around in shock.

"What in the name of the angel is this?" He demanded, as the boy he'd dragged in rubbed his neck sorely. He looked over at the bathtub where Percy was still waving, and made a face of utter confusion.

'Izzy, what the hell" he demanded, grabbing the kid trying to leave by the hood of his parka and pulling him back.

"Oh calm...down" she said, yawning. She got up and made her way over to Alec, prying his fingers away from the kid.

"HEY" Percy yelled, trying to sit up but having trouble without his legs "Nico, what are you doing here?"

"Guess who finally sobered" Clary mumbled, and walked over to Isabelle and Alec. Piper had fallen asleep with her head against the bathtub, and Leo's eyelids were drooping, as he picked himself up and stumbled.

Percy seemed to have realized he had a tail, because he screamed a scream so pitched everyone cupped their hands over their ears.

"HOLY POSEIDON" he screamed. He looked down at his tail then back up again at everyone "I'M A MERMAID".

"Tell me about it" Leo said, rolling his eyes.

Annabeth sort of wished that Frank would change the channel, really. They'd been watching infomercials for a good two and half hours...and thirty seven seconds. But hey, who was counting? Frank had carried her downstairs at around nine, her arms and legs tied together. Jonathan was gone, and Frank did not listen to her. He held the remote in both hands, staring blankly at the TV seated next to Annabeth but not touching her. She'd had an inch on the end of her nose for a good fifteen minutes, and had a very strong urge to buy the slicerdicer, and thought, for certain, that she was going insane.

"Frank" she said shifting very uncomfortably towards him "could you try to tell me whats going on?"

He looked at her out of the corner of his eyes and then away very quickly, his jaw clenched. Annabeth watched with a mix of horror and pity as Frank twitched and jumped slightly, the veins in his neck and forehead protruding and a bead of sweat forming at his temple. Then, suddenly, his back snapped forward, and he gasped a low rattling breath in.

"Annabeth" he choked, gripping the couch so hard that the material started to rip "Annabeth you need. to. get. out. of. here.".

"What...Frank, I'm tied up" she said. She'd gone over so many plans in her head, but none of them made any sense to her, or would work "And theres no door".

"Thats..because" he took a deep breath in, his eyes threatening to roll back in his head "its invisible". He lifted a trembling arm and pointed to a bare wall by the kitchen, and Annabeth nodded.

"How do I get out?" She asked hurriedly.

"Stick, the...the stick thing...the patterns" he gasped, his breath coming out shallowly.

"What do you mean?" She yelled, frantic.

But he collapsed, and his eyes rolled back, his limbs going slack.

"FRANK?" She yelled "FRANK? FRANK?"

"Frank" she heard a male voice behind her mock "Fraaaannkkk! Call all you want, he's not waking up like that again".

"Wha-" she whispered, turning her neck as far as it would go.

But Jonathan had already pulled out his sword, and he cut Annabeth across the face with it, and she winced.

"Don't do that again, sweetheart" Jonathan whispered in her ear, and she felt her teeth grind "now its time to try putting on some runes".
