FAIR WARNING: THIS STORY IS REALLY SHITTY, OLD, AND DESTINED TO BE INCOMPLETE FOR ETERNITY. HAVING READ THIS WARNING, DO NOT COMMENT/SEND ME MESSAGES ASKING FOR UPDATES. THANK YOU. THIS HAS BEEN A PSA. What happens when demigods go to Hogwarts? Chaos, secrets, and lies, that's what! The Seven, Nico, and Reyna are part of an exchange program planned by Chiron. Can they hide all their secrets before it's too late? The Golden Trio, Ginny, Neville, and Luna are assigned to guide the Americans around. Can they risk having the exchange students around them? This is a story about how two very different groups of people set aside their differences to defeat a greater enemy- for neither can win while the other is defeated.

Percy Jackson just won his own war, and now Chiron wants to send him, Annabeth, Nico and Thalia to a wizard school in England? Not to mention it's called Hogwarts. What kind of name for a school is that? Their quest is to protect some guy named Harry Potter, and stay undercover. No one can know he's a demigod. Well, off to Hoggy-Warts. WARNING: I wrote this when I was twelve, and it has lots of hate towards Harry & Ron in the beginning, even though I love those guys. It's not very good, sensible, or developed! Read at the risk of your own disappointment and disapproval!!

I DO NOT OWN PERCY JACKSON OR HARRY POTTER. ALL RIGHTS GO TO RICK RIORDAN AND J.K. ROWLING. P.S. THIS FANFIC IS TOTAL SHITE

A broken Percy goes to hogwarts by request of Hecate after wanting a new life away from all the usual demigod madness.

Percy Jackson is broken. After the Giant War, Camp Half-Blood's protective barriers were destroyed, and he was the only one who escaped. He watched his friends and family be slaughtered by an army of monsters, and he has nothing left to lose. When Professor McGonagall comes to ask if he could teach a class called Defense Against the Dark Arts in a school called Hogwarts, he agrees. But there was one thing that will be difficult- not revealing that he is a demigod. Will he keep the secret, or will the year end in disaster? I do not own the Percy Jackson series, Harry Potter series or the characters in them. They are owned by Rick Riordan and J.K. Rowling.

Percy gets a letter from Hogwarts asking him to attend the school for sixth year after his holidays.What happens when the two worlds crash? Takes place after the Giant War and Wizard war.
