What happens when Nico is sent to teach at Hogwarts? Will his cover be blown? Will he succeed in teaching the witches and wizards what they need to know for the battle to come? THERE IS TRIGGERING SELF HARM CONTENT

Harry Potter is used to being the Hero of his world. He and every other wizard believes he is the destined savior of the world. Now that wizard world knows Voldemort is back Harry is going to need protection. Percy Jackson has finally defeated Gaea and saved the world yet again and thinks things will start to calm down. Unfortunately for him, he is that protection. Except he can't do it alone. He is going to need the help of six certain people. Worlds collide in Demigods at Hogwarts. (Guys I suck at summaries. I swear the book is better.)

Chiron decides to send 14 of our favorite demigods to Hogwarts on an extremely important mission, because: Camp Half-Blood is a mess. The power of prophecy is unavailable. The magical border is down. Camp is constantly being attacked, and demigods are dying left and right. Once again, the gods don't seem to care. New dangers are arising, and the camp seems doomed. Hogwarts is doing quite good. Completely repaired from the aftermath of the battle, the school is thriving. The wizarding world has something the demigods don't. Will they save them, or destroy them? And will the demigods be able to survive a whole school year at Hogwarts, pretending to be normal?

The half-bloods go undercover at Hogwarts, will they finish the year? Who is going to mess up their quiet? Because let's face it somebody will, read to find out. Disclaimer I own nothing JK Rowling owns all the wizards and Uncle Rick owns all I'm currently going through these chapters and rewriting them so they make sense and so the story will suddenly get really bad half way through, sorry in advance!

When the Seven, Thalia, Nico and Clarisse are asked to go on a quest to Hogwarts, to befriend a few wizards, the golden trio and their friends to be exact. But the golden trio are suspicious of this new bunch.... they're not normal wizards. Will the demigods be able to keep their secret or will the golden trio find out? Disclaimer** I do not own the Characters!! Just the plot!!! Some of the plot I have inspired off other people. The characters belong to my favourite people in the world: Rick Riordan and J.K Rowling. Without whom my life would consist of me sitting on my bed crying all day. [ I promise will finish this story, but entering my last years of school is very time consuming. But I will finish this!! Additionally, each chapter is written sort of like an episode, they're connected but in small details as building blocks. Only the last few chapters will be heavily connected and left on cliffhangers. But, as far as the story goes now, if you read it as is you won't be hanging on for anything. ]

Percy, Annabeth, Piper, Jason, Hazel, Frank, Leo, Nico, Will, and Thalia are sent on a quest to Hogwarts. Harry, Ron, and Hermione, as well as a few other students, have been invited to redo their final year. Will everything go according to plan or will jealousy and love get in the way? Disclaimer for the whole story. I own nothing, but the plot. All rights go to Rick Riordan and J. K. Rowling.

In the wizarding world, Harry, Ron and Hermione are invited back for their seventh year at Hogwarts. The war has left a huge impact on everyone, and the three are hoping to be able to relax and enjoy their final year at school. But honestly, fate just has to- [better not finish that sentence. After all, the Three Fates can get very touchy...] At Camp Half-Blood and Camp Jupiter, another quest has been issued, and much to the complaints of everyone, the Seven, Thalia and Nico are sent to Hogwarts. They soon find out that there is no time to enjoy themselves, though, because something primordial, something ancient and powerful is stirring, and it is stirring awake... "Nine half-bloods roam the sorcerers' land." "Child of the dead halts second chance." "Join the fates of worlds beyond," "Who unite to battle the bane of bonds."
