Well it's Percy Jackson and Hogwarts. Timeline : Seven know each other and are 17 but for the sake of the story, they fit in with fifteen year olds . 5th year for the trio (haha Percy and Umbridge Haha). And LET'S DO THIS

Harry Potter is used to being the Hero of his world. He and every other wizard believes he is the destined savior of the world. Now that wizard world knows Voldemort is back Harry is going to need protection. Percy Jackson has finally defeated Gaea and saved the world yet again and thinks things will start to calm down. Unfortunately for him, he is that protection. Except he can't do it alone. He is going to need the help of six certain people. Worlds collide in Demigods at Hogwarts. (Guys I suck at summaries. I swear the book is better.)

The half-bloods go undercover at Hogwarts, will they finish the year? Who is going to mess up their quiet? Because let's face it somebody will, read to find out. Disclaimer I own nothing JK Rowling owns all the wizards and Uncle Rick owns all I'm currently going through these chapters and rewriting them so they make sense and so the story will suddenly get really bad half way through, sorry in advance!

[Completed] This takes place after the Deathly Hallows and after the Giant War. Nobody important dies, thankfully, nobody at Hogwarts is a demigod or demigoddess that knows that they are.

This story is adopted from @LunaNorah and this is my first fanfic. That's all that I'm telling you so just go ahead and read the story!

Takes place after the Deathly Hallows and the Blood of Olympus Percy Jackson thought he could finally live a normal life. He was going to fail high school, be the captain of the swim team, spend a whole, normal year with Annabeth. Yup, not gonna happen. Harry Potter has to redo his seventh year at Hogwarts. At least he gets to be with his best friends. Then some new kid shows up and he can't help but be a little jealous. He was the grandson of Voldemort and the girls were just falling at his feet. Even Ginny and Hermione were swayed by this boy. He was a death eater, and Harry could prove it. Luckily for him, the Triwizard Tournament was right around the corner. If the death eater was chosen, it'd be fun to watch him fail. Warning : Ron/Hermione and Harry/Ginny did not happen yet. Second Warning : Sirius, Snape, and Dumbledore are still alive. Just a disclaimer for the whole book : All rights go to Rick Riordan and J. K. Rowling Cover courtesy of @thatgirlariadne

FAIR WARNING: THIS STORY IS REALLY SHITTY, OLD, AND DESTINED TO BE INCOMPLETE FOR ETERNITY. HAVING READ THIS WARNING, DO NOT COMMENT/SEND ME MESSAGES ASKING FOR UPDATES. THANK YOU. THIS HAS BEEN A PSA. What happens when demigods go to Hogwarts? Chaos, secrets, and lies, that's what! The Seven, Nico, and Reyna are part of an exchange program planned by Chiron. Can they hide all their secrets before it's too late? The Golden Trio, Ginny, Neville, and Luna are assigned to guide the Americans around. Can they risk having the exchange students around them? This is a story about how two very different groups of people set aside their differences to defeat a greater enemy- for neither can win while the other is defeated.

Another prophecy, another quest. Seven demigods enrol as students at the Hogwarts School of Witchcraft & Wizardry. They're hoping to help the wizards and witches defeat...well, they have no idea. The poor demigods get an overflow of homework and boredom (or not?) as they wait for something to happen. But the Titan and Giant War were not the last war for the demigods, and neither was the Second Wizarding War the last for the wizards...this is. - Cover made with Viria's art Highest ranks - 1 in demigods, 5 in hogwarts, 3 in percy jackson, 1 in annabeth chase, 1 in nico di angelo, 2 in leo valdez, 4 in crossover, 1 in percabeth, 19 in harry potter, 11 in pjo, 1 in hp

Percy just wanted some peace and quiet. He finally defeated Gaia, the world is normal...but the fates, as usual, have a different idea. Percy, Annabeth, Jason, Piper, Thalia, Leo, Nico, Hazel, and Frank have to play bodyguard. For who, might you ask? Someone special. Someone who is going to need help, since his worst enemy has returned, bringing one of Percy's along for the ride. Who is this kid? Why, Harry Potter, of course! ***As you can tell, I don't own Harry Potter or Percy Jackson, props to those authors for actually coming up with the idea! I do have a few OCs but that's it!***

When the Seven, Thalia, Nico and Clarisse are asked to go on a quest to Hogwarts, to befriend a few wizards, the golden trio and their friends to be exact. But the golden trio are suspicious of this new bunch.... they're not normal wizards. Will the demigods be able to keep their secret or will the golden trio find out? Disclaimer** I do not own the Characters!! Just the plot!!! Some of the plot I have inspired off other people. The characters belong to my favourite people in the world: Rick Riordan and J.K Rowling. Without whom my life would consist of me sitting on my bed crying all day. [ I promise will finish this story, but entering my last years of school is very time consuming. But I will finish this!! Additionally, each chapter is written sort of like an episode, they're connected but in small details as building blocks. Only the last few chapters will be heavily connected and left on cliffhangers. But, as far as the story goes now, if you read it as is you won't be hanging on for anything. ]
