1st December

Chapter OneJace sulks and whines while Percy complains.

A/N: Hi Everyone! I know this is yet another story but this one was written for my friend as an advent calendar for Christmas even though it has nothing to do with Christmas. Just to let you all know all five of my Shadowhunters OCs will be in this and practically all my Percy Jackson OCs as well.

Also, just so y'all know in this Luke Castellan is not dead and neither is Raphael Santiago.

OCs-

Marissa Marco, Madeline Solace, Nita di Angelo, Lupa Graymark, Jacob Alqamar, Artemis Nightpine, Morrigan Lightwood and Adriana Castaneda.

Disclaimer: I do not own the PJO or TMI universe or its characters. Rick Riordan and Cassandra Clare do.

Shadowhunters:

"I swear I'm going to murder the Clave." Jace moaned as he threw himself down next to Clary on Magnus' sofa.

"Welcome to Magnus' home for depressed and reckless Shadowhunters." The Warlock declared sarcastically.

Jace only smiled mockingly then turned to his two sisters and brother "I can't believe it. All Shadowhunters under eighteen must attend mundane school for a taste of other cultures. Who do they think they are!"

"Oh, I don't know The Clave." Alec said with a smirk.

"You're only saying that because you and Morrigan don't have to go." Jace retorted sulkily.

Alec stood still for a second then nodded, hiding his face to prevent himself from laughing when his twin sister came in and crossed her arms smiling at Jace.

Izzy held back a laugh and then said "It doesn't have to be so bad I mean we're going to Simon and Clary's old school. What was it again? Goode?"

Clary nodded and moved to cuddle into Jace's side. "You'll get to see me and your best friend all day every day."

"Simon is not my best friend he's annoying!"

"How do you know I was talking about Simon."

"He's the only one who you could be talking about."

Clary sighed and went quiet.

"Well, I personally found that very entertaining." Magnus announced.

Alec finally let himself laugh.

Morrigan couldn't help but smile too. "Do you know who else is going?"

Simon finally piped up, "Me, Izzy, Clary, Jace, Lupa, Jacob, Raphael and Adriana."

Jace looked surprised at the last four names on Simon's list. "Two things, one, how do you know and two why are Lupa, Jacob, Raphael and Adriana having to go?"

Magnus moved towards him his hands bent bad in a manor to present himself. "I told him earlier because he wanted to know and as to why Lupa, Jacob, Raphael and Adriana have to go, I talked to Luke and he said it would be, beneficial? for Lupa to, um be one with the mundanes and Jacob is just there to make sure she doesn't leave. Anyway, on the more impressive hand I created a sunscreen which can stick to a vampire's skin just enough to allow them some freedom like being in a car during daylight or under a canopy in sunlight, while direct sunlight will still burn them it will let them be in a classroom. Plus, those two need to work on their people skills and they're the least likely to attack, murder and turn a mundane."

Jace nodded pretending that he took that all in. However, in reality all that he really caught was 'Luke, be one with the mundanes, make sure she doesn't run away, sunscreen, some freedom, least likely to attack, and murder.'

"Speak of the devil and he will come." Magnus remarked as there was a knock on the door. It was around 9 O'clock in the evening, meaning technically be anyone as it was dark enough for even vampires.

When the warlock opened the door four people's silhouettes were in the doorway but as they moved into the light, they took the shape of Lupa Graymark, Jacob Alqamar, Raphael Santiago, and Adriana Castaneda.

"Really Magnus, you've hurt me. I'm damned meaning I'm already classed as a servant of the devil." The female vampire's voice rang out through the room but as she walked even further forward everyone could see she was trying to hold back a laugh.

Magnus just smiled. "Dinners ready just so you all know. You can all camp here tonight just to make it all easier then I can drop you off to school tomorrow."

Magnus and all the over eighteens shared a look and Jace could only wonder what hell was in store for them.

Demigods:

"Chiron please. We'll do anything. Please don't make us go to school. Please."

Chiron shook his head "It has been decided by the gods. It is what is best for you and the others."

Percy sat down grumpily on the chair "Two questions."

Chiron waved his hand, and indication for Percy to continue.

"Where are we going and who else is going to be there?"

"You will be headed to Goode Highschool. With you there will be: Annabeth, Leo, Jason, Piper, Frank, Hazel, Nico, Nita, Will, Maddie, Thalia, Reyna, Calypso, Grover, Clarisse, Chris, Travis, Connor and Katie."

"Long list." Percy observed.

Chiron nodded a look in his eyes Percy couldn't recognise

"A lot of campers needing a break."

Percy's mind flooded with memories from all the wars and battles and hardships him and everyone else had been through and realised he really did need a break and if he did then so did everyone else.

"Go Percy, go tell everyone else. Oh, and take the list you'd have a hard time remembering everyone on it without it."

Slowly, the son of Poseidon went around telling the campers that it applied to, to pack their things and get ready to go to school. Yay! Sense my sarcasm.

When he got to Leo, Percy could visibly see excitement fall from him.

Leo's eyes went wide in horror "School!"

Percy nodded solemnly. Pretending to wipe tears away from his eyes he said, "I know my dear friend but it has been decided by the Gods."

That was when Annabeth came up behind him.

"Come on guys you're the 5th and 6th people I've talked to where I had to convince them that going to school isn't such a bad thing."

Leo snorted and a faint "Uh-huh" could be heard to come from him.

Annabeth sighed, "You'll see. Anyway, I expect you to be ready to leave at 8 O'clock so that we can get to school on time and Chiron can sign us in."

Percy and Leo nodded then dispersed, leaving Annabeth contemplating events earlier on during the day.

Before lunch she walked in on Luke, Marissa and Chiron all talking only to suddenly stop when she came on. Then a similar thing happened about an hour ago but this time with Mr. D. whatever was going on she was sure they would find out soon.

A/N: Thank you guys for reading this. I finished this on the 2nd so technically it's a day late but I'm going to gloss over that.

I really hoped you enjoyed this.

Please review so I can make this better and constructive criticism is welcome.

Have a wonderful 2nd of December!

Enjoy!
