I swear, I don't own the Percy Jackson/Lost Hero series... or the Harry Potter series...yet

Camp Half-Blood

It was a normal day for everyone at Camp Half-Blood. Well normal to Chiron who has been around tons of ADHD children of the gods for well, gods know how many years now. Everyone was off doing something whether it be Percy and Annabeth making out underwater (everyone knew they did it no matter how much they tryed to keep it a secret,) or Nico scaring some of the newer campers with his raising the dead trick, others were learning how to speak ancient Greek, how to use various lethal weapons, or figuring out how to get to the top of the climbing wall without getting burned to death by the lava spouting from the top. All and all considering how things could've and have been, Chiron thought that it had been a pretty good day. At the moment he was watching everyone at dinner, the Aphrodite cabin was launching lipstick and mascara at the other tables and the Demeter cabin was still upset at the Hermes cabin for putting chocolate bunnies on the roof of their cabin again. 'Well' Chiron thought,' I could get their attention now well the chaos is at one of the lower levels or I could do it at the campfire later and avoid very high levels of chaos with ADHD children around a fire.' Let's just say the decision wasn't to hard for him.

"Heros, I have some interesting news," He stopping for a second looking around. "And I think that it would be in your best interest to pay attention, can someone please remove the pencils from Clovis' nose and wake him up."He waited as a guilty looking camper walked up and both woke up Clovis and removed the 24 pencils that had somehow made it into his nose... again. As soon as Clovis was somewhat coherent and the child of Hermes sat down Chiron went on. "There is another thing that has been kept from you," nearly every groaned, it seemed that things like this happened a lot. "There is another secret world, out in Europe, we are all going to the one in Britain."

"Ok, just wondering, how many secret worlds are there and why do we seem to have to go to each of them!?" Leo Valdez nearly shouted.

"I cannot answer that question, and this world is secret for a reason." That might keep them slightly off topic for now.

"Does that mean that if we meet them they'll most likely start war or just try to kill us out right?" A girl spoke up from the Iris table.

"No, we were invited this time, now if you let me finish, this was a world created by Hecate and her descendants, these people call themselves wizards and witches, they use wands and are slightly medieval." Cue every single camper looking at me like I'm insane again, I've gotten that look a lot.

"And why did these people invite us over?" Nico Di Angelo asked.

"One of their leaders Albus Dumbledore heard of us most likely from Hecate and thought to invite us to participate in a rather dangerous and lethal tournament that is taking place at his school Hogwarts."

"And we said yes to that because.." Another camper trailed off.

"You're asking that question, I want to know who names a school Hogwarts!" Another camper shouted out, there's the ADHD we know and hate at moments like this.

"Well I just got the information from the gods not to long ago and they said that everyone has to go and that includes the Romans who are currently being told the same by Lupa, and the Hunters of Artemis by said goddess. We will be leaving in a week on the Argo 2 and yes, your mortal parents have all been contacted and have agreed, so I suggest that you IM home for some winter things because we will all be there the whole year. Enjoy the rest of your meal." And will that Chiron simply let chaos reign, fully knowing that there wasn't a force in the world that could stop a bunch of excited demigods.

The Great Hall

Dumbledore sat in the Great Hall over looking all of the students in Hogwarts. He really didn't want to tell them that quidditch was cancelled for the year, the thought of what some would do to him was terrifying, especially what Oliver Wood would've done to him, thank god wait, the gods that he graduated. That boy really was something when it came to the sport, he truly did love it. Anyways, back to the problem at hand how to tell everyone, maybe he should start to rehearse speeches or at least not make them up last second anymore. Well might as well get it over with.

"Welcome to Hogwarts to the new students, and welcome back to the old," He began. " I have the usual start of term announcements and one special one. To all years, you must stay out of the Forbidden Forest, can you not guess why we named it that," he said while looking over at the golden trio and the Weasley twins as usual. "Next to all those who don't know, there is no magic in the halls and there will be a list of forbidden objects posted on the door of Mr. Filches door." Again usual, the part he was dreading was coming soon. "Also we have a new defense against the dark arts teacher Professor Moody." The normal round of applause and now the part he had been dreading. "And this year there will be no quidditch cup." The students roared in protest the Weasley twin being some of the louder ones. "This year Hogwarts will be hosting something different instead. A tournament, Hogwarts, Durmstrang, Beauxbatons, and a few different groups that are to remain a surprise. The surprise groups shall arrive in a week and I will tell you they are not witches or wizards," there was another roar, particularly from the slytherins. "But they are by no chance muggles." Good now they are all confused, not a wich or wizard but not a muggle, that's all they think there is out there. "Well off to bed pip pip," and now they are confused and slightly irritated, fun.

There's the first chappie!

Please review, and give suggestions to which demigods should be in the tournament
