Demigods Vs Magic. by KnightCrawler101

Part 1 of the "Demigods...." Anthology. Demigods and Wizards. Two groups of supernatural ability. So similar, yet so different. Ever wondered, which one would come victorious in a battle to the death? Well, it happened. Their worlds collided head-on, erupting in a swirling inferno no one could have predicted. It was survival of the fittest, the most ruthless. Two sides entered the battlefield, but only one will walk out. Percy Jackson and Harry Potter knew this. And they were ready. To fight, and to kill. "Neither can live while the other survives." Let's see who won, shall we?

Annabeth Chase and the Ignorant Wizarding World by AsexualConfusion
48 parts Complete
(This is the sequel to a story already finished on my profile) In between her new school and getting Percy into college, Annabeth is back for another (sort of) year at Hogwarts. But this time, things are a little different. For one thing, there is now the threat of a wizarding mass murderer looming, and no one seems to believe that he's actually back. Even more, the Ministry of Magic is making out Annabeth to be some sort of mastermind who convinced Harry Potter and Dumbledore to lie about Voldemort's return. For another, the Ministry of Magic has placed one of their own inside Hogwarts as a teacher--- someone fully dedicated to the Ministry and hates half-breeds like Annabeth. Annabeth is supposed to be protecting Harry from Voldemort and other threats, but how can she do that when there's a shrunken pink toad watching her every move?

"You can't seriously expect us to go to a school for magic!" "You want us to what?" ~~~~~ Dumbledore sends out a distress call to the demigods. Voldemort is back and the gods made the mistake last time to refuse the wizard's call. Chiron sends Nico, Will, Thalia and Percy to go protect Harry Potter, the targeted wizard who Voldemort wants dead. The demigods must protect and defend Hogwarts from the dark wizard, but keep their identities as demigods secret at all costs. No one must know because it could put them in danger. But the golden trio keep persisting that the new students are up to no good. They make the secret terribly hard to keep. Contains Percabeth, Solangelo, and others ----- I don't own Percy Jackson or Harry Potter, credit goes to Rick Riordan (who is amazing) and J.K Rowling (who I do not support).
