Wars he could handle - piece of cake! Another evil grandfather out to get him . . . now that was stretching his patience too far.

AU, Orphaned from a lab accident, Danny Fenton was taken in by Vlad Masters. During an attack by Death Eaters, Danny miraculously survives, bringing his identity as a halfa to the attention of the Headmaster of Hogwarts and the Dark Lord. Professor Dumbledore sent for him to enroll at Hogwarts as a 2nd year for his safety, where Danny must learn to balance his half-life secret with his magical studies. Contains torture, violence, some language, mentions of suicidal thoughts, and all that fun jazz. Might have some slight OOCness and Dark themes. Scratch that, there will be lots of Dark themes. Phantom of the Chamber can also be found on fanfiction.net, Quotev, and AO3. If it is found on any other sites not mentioned here or my profile, then please don't read it there because it was placed without my consent.

Sally died protecting her nephew Harry Potter. Lilly and James Pottor come back home to see her dead and Harry crying. But they notice something else is wrong. Their nephew Percy is gone. All rights go to Rick Riordan and JK Rowling So in this story there is going to be a lot of people who aren't dead. There's Snape, Sirius, Lupin, Tonks, Lilly and James (of course!). Also Fred not going to be dead because separating the Weasley twins is like separating the Stolls! Blackjack and Percy are going to seem more close in this. I've only seen the movies to Harry Potter so sorry for incorrect information! Just tell me and I'll try to fix it!

Travis and Conner try to play a prank on Percy using an object they got from suspicious red headed twins. Without fail something goes wrong and Percy vanishes .... only to end up on grounds of Hogwarts. Same story but now with an updated cover. (Just a FYI, this is after the war with Gaea, but before Dumbledore died so I think that makes Percy older than Harry. This was also one of my first stories, started when I was much younger so the writing is not my best.)

"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). Also, the first few chapters are bad. Keep reading, it gets a lot better. Most Impressive Rankings: #1 in Solangelo, #1 in Solangelo (May, 2021) #1 in Percabeth, #4 in Percabeth, #2 in Percabeth #2 in Crossover #9 in Percy Jackson #1 in Nico, #1 in Nico (April-May, 2021) #1 in Annabeth #1 in CampHalfBlood #1 in Gods {Book 2: Half-Blood Princes - Completed} {Book 3: To Thwart The Darkness - Completed} Credit to @-Is-A-Belle- for making the amazing cover.
