In a world where gods and magic clash, Percy Jackson-demigod, hero, and grandson of the most feared dark wizard in history-is sent to Hogwarts on a dangerous mission. His job? Spy on wizards and determine if they're a threat to Olympus. But the more time he spends in the wizarding world, the more tangled things become. Between dodging bloodthirsty monsters, uncovering hidden family secrets, and dealing with wizards who either fear him or want to kill him, Percy has enough on his plate. As tensions rise and dark forces stir, Percy realizes the real danger might not be the mission... but what happens if he starts to belong in a world that was never meant for him? ps: honestly I don't even think its possible to describe this story.

It is three months after Gaea's defeat and Camp Halfblood is hanging by a thread. Percy is a shadow of who he was; a war hardened warrior. He takes on quest after quest to distract him from his losses, but he is still broken, no matter how much he tries to stay strong for the Camp. During a sudden visit to his mom's house, he gets a glimpse of her past while being pulled into another war. His PTSD is at an all time high and he was finally starting to accept their deaths when he discovers the woman he calls mom has her own skeletons hiding in the closet. And they are only now beginning to crawl out from the cracks. Albus Dumbledore and the Order of the Phoenix are running out of options. Voldemort is getting stronger while their numbers are dwindling. In a desperate attempt to gain allies, he tracks down an old student of his. Sally Jackson, or, as she was known, Sally Potter. Joined by some of her old classmates and friends, he tries to persuade her to join their war effort. To their surprise and disappointment, she adamantly declines only for the reunion to be interrupted by her teenage son. One who possess magic, the one they never knew existed. The Halfblood Wizard: Perseus Jackson. ~~~ Previously Titled Halfblood at Hogwarts New Title by HorcruxDemigods7 Cover by Inheritance21 ~~~ "You know when you find a bunch of 'okay' books on Wattpad but every once in a while you find one that you just have to stay up 'til the sunrise to finish? This was the book to make me stay. Percy's persona is wonderfully written, the grammar is perfect, and it is completely original. Well done and I can't wait to read the rest." ~Unrealqueen "DAM YOU ARE THE GODDESS OF WRITING" ~Labinzel "This is one of the best stories on Wattpad period. Not just in fanfiction or crossovers but out of all the books on Wattpad. This is THE BEST and my FAVORITE. You are such a good writer!!" ~fanficreader14 ~~~

Percy isn't a demigod, but there's something equally unusual about him, even for the Wizarding World. When a magical accident at school draws the attention of Hogwarts Headmaster Albus Dumbledore--and the wrath of Smelly Gabe, Percy must leave the country for his own safety. He journeys across the ocean to learn control of his wayward magic, and meets a group of four other mischievous troublemakers. However, Percy's time at Hogwarts is perhaps not as normal as he would like, what with his out-of-control magic and the dangerous secrets of his best friend, Remus. This story considers All The Young Dudes by MsKingBean89 as canon, so there is a lot based off that storyline, although it will diverge a lot. I do not own the Marauders plot for ATTYD, just the additions and changes of Percy. So I guess this is a fanfiction of a fanfiction? There will be some PJO characters, but the Greek Pantheon does not exist here. This is Mortal!Percy in the Marauders Era (but don't worry, Percy's still exceptionally odd). Content warning for different forms of oppression, I am making characters more representative of identities the way I wish Rowling and Riordan had done.

The Wizarding War has ended and Percy is ready to start at Hogwarts as Deputy Headmaster. But the aftermath of the war is not quite what he hoped it would be. The Wizarding World is wary of Percy and unsure of how to handle the Greek Pantheon. And there is still lingering trauma and resentment of those who chose the wrong side... While Percy navigates his new job, his relationship with Hermione, and his mysteriously failing health, he cannot help but be reminded of his first five years at Hogwarts. Because Percy's learning that to move forward in the future, he needs to come to terms with his past. Before it kills him. (Essentially, this is both a prequel and finale to the Nexus series)

Albus Dumbledore was surprised when he found a file on one Perseus Jackson Riddle, grandson of Voldemort. He was even more surprised when the boy was a powerful wizard at only thirteen years old. Harry and Percy enter their third year together, and although Percy has been introduced to the world of gods, he has yet to meet the Wizarding World. There will be cursing in this story.

"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.
