What happens when Camp Half-Blood and Hogwarts meet? Percy Jackson is asked to teach at Hogwarts as the new DADA teacher, but will he last as a professor? Voldemort is getting ready to kill Harry, and the war is coming up. Will the demigods ally themselves with the wizards? Or will they let their differences split them?

Headcanons of Harry Potter, Percy Jackson, Heroes of Olympus, Artemis Fowl, The Hunger Games, Doctor Who, Divergent, Sherlock and books written by John Green. I don't own any characters and I am not plagiarising (at least intentionally, I don't know many legal boundaries). These are a work of pure imagination based on characters, plots or scenes of books I have read or TV shows I have watched. Quite a few of these are original, but I have borrowed a few from Tumblr. Fair warning: I aim for your feels.
