Percy was looking forward to some down time with his girlfriend Annabeth after the Giant War ended. What he didn't expect was an old man claiming that he was a wizard. If that wasn't enough, it turns I out that he's not just any wizard, he's the grandson the the dark lord, Voldemort

After being summoned by Hades and Hecate, Nico must leave his boyfriend Percy to go help out one of his dad's friends and teach defence against the dark arts at Hogwarts. However the Golden Trio seem very wary of their new professor and Nico's quest might be more eventful than he planned.

The Order finds out that Voldemort has a grandson. Now there is a race to find him and get him on their side. They have no idea what they are in for. Set after the HoO series and during Order of the Phoenix

Percy has been through a lot, being kidnapped, having his memory wiped, several battles, two wars. He does not need anything else to happen. Too bad the wizards, which are real apparently (!?), didn't get the memo. Well, you know the phrase, when in Rome. (Heh, Rome, get it?) (After BoO and during Order of the Phoenix.) [I obviously am not Uncle Rick or JK Rowling.] {Anyone else got that Hufflepuff Pride?}

Marinette didn't expect a new student suddenly popping up in her class with the name Percy Jackson. She also didn't expect him to be a mysterious type of person.

When Percy is summoned home from camp to see some weird people on his couch, let's just say he's confused. When he finds out that he has another evil relation, he's not happy. Well, off to Hogwarts. Harry is astounded. Voldemort- the lowlife scum of the wizarding world- has a grandson. Now Dumbledore wants him, Hermoine, and Ron to get him, and become friends. Harry must be crazy because he agrees to go. Set after PJO but before HoO ( I want him 15/16) and during OoTP Check out my other crossover: Percy Jackson - the New Hogwarts Teacher Cover created by @Emer28702000
