Voldemort and Gaea are working together. The Argo ll has crashed, and the Seven of the Prohecy find themselves at Hogwarts School of Witchcraft and Wizardry. Two worlds mix... and to preserve them, Gaea and Voldemort must be beaten...

When Leo discovers a way for demigods to use phones, the gang celebrate on a trip to England. But what troubles await them when they find out about the magical wizards and witches who live there. Takes place in the summer before the fifth year of Hogwarts. Better than sounds. Pjo/HP crossover. Rated T just in case.

It's bad enough Grace is a demigod but now she's a witch! Read about Grace and how she grows up.

What if when Leo tries to save Calypso, she dies and Leo snaps? Chiron sends Piper,Jason, and Leo to Hogwarts to help Leo overcome his depression, but also to protect Harry... Placed after Blood of Olympus and during Order of the Phoenix. Better than it sounds! Disclaimer : I own nothing!

Skyler has been training all her life not knowing why under her dad, Samuel Slytherin. When she learns she feels like she is under the sky with Atlas. But Skyler will have help with friends that are Demigods and Wizards (and Witches). Will Skyler stand strong or will she crumble under the pressure. This is also a little hurt/comfort

The demigods' destinies have been changed by Titans. Their memories have been erased and they are now wizards.. but a dark prophecy declares that Voldemort will not be the only villain rising to power. It is said Percy Jackson will defeat the second villain - but maybe not? Destinies of wizards and demigods will be entwined in this story. Possible AUs, and I suck at summaries lol

WELL, IF YA'LL ARE TOO LAZY TO READ THE TITLE... It's a simple, insane game of truth or dare with four demigods and four witches/wizards. The hostess, a crazy, Demi-Witch named Alex.

A kidnapped God, a dark wizard and an evil force so ancient, many had long forgotten it. James Sirius Potter and Rose Weasley must join three demigods on a life endangering quest; overcoming suspicion, fear, and doubt. Only both their worlds together can defeat the enemy, but the prophecy says not all will make it back alive... ON HOLD. Sorry guys... :(

When Percy stumbles across a baby lain carelessly on the doorstep, he couldn't resist the urge to pick him up, cradle him to his chest, (crumpled) letter and all. As the son of Poseidon looked into the child's green eyes, he swore that come hell or whatever that seemed to cling to the child Percy would die before anyone harmed a hair on his head.

In this epic tale, heroes Percy Jackson and Harry Potter meet again. They must join together this time to fight a new evil, greater than anything they have ever faced before. I do not claim to own the Harry Potter, Percy Jackson and the Olympians, or Heroes of Olympus series.

Percy Jackson just got out of a war. Harry Potter is just about to enter one. What could the two have in common, except for perhaps their parents?

Wizards aren't what you think they are; perhaps they descended from Half-Bloods. The wizards decide to colonize in America. Harry, Ron, and a few other Aurors go scout the U.S., but something goes wrong. Now James is going to go to Camp Half-Blood, and Harry is being held prisoner.

When the Demigods have to leave Camp Half Blood to got to Hogwarts - protecting Harry Potter is their quest. Harry's sixth year is retold with Umbridge's return and Dumbledore's death.

This is a reading the books story between Harry Potter and Percy Jackson (mostly because of my OC). What happens when you send some demigods back in the past to try to change the future? Chaos, hilarity, and, of course, a lot of debris. Takes place after the second Titan War, and the Battle of the Department of Mysteries. Read, review, have fun. I hope this is my usual standard!

Percy's life was bliss, until a freight truck turns his world upside down. When the Olympians don't help him, he finds about a possible way to set things right: The Resurrection Stone. He roams the world to find it, but things happen and he looks at another way to set things right, without the stone. Or will he?

While the Greeks and the Romans have been age old enemies, the demigods have never had a problem with wizards. Harry's daughter is starting Hogwarts, a Hecate camper is a British witch, and a pair of best friends look to start the next war. Explore the life of a demigod trying to keep her two worlds separate while they are are on an unavoidable collision course.

The giant war has ended at the cost of Annabeth,mean while Hogwarts they need a new DADA teacher.Will Percy be healed in the comfort of his students or will he stay lifeless to the world.

Harry Potter découvre qu'il a un frère et de plus un demi-dieu, le fils de la mer et qu'il a aussi deux demi-sœur : Phoebé et Naomi-Lu. Ensemble, ils réuniront leurs forces pour vaincre le Seigneur des Ténèbres et le Seigneur des Titans. Ils sont les enfants de la mer.

A Weasley twin vanishes from Grimmauld Place. A Stoll disappears from Camp. They are each left with another twin from another world. Summary sucks, sorry.

The second giant war has ended but as Percy and his crew try to relax they find out that an evil wizard (voldemort) is trying to resurrect all the enemies they have defeated and to stop him they must go back in time to protect and help the only person who can defeat him (Harry)

WHAT HAPPENED IF PERCY JACKSON,THALIA ,NICO,AND THE REST OF THE SEVEN WENT TO HOGWARTS TO PROTECT HARRY POTTER ... RATED T FOR SOME SWEARING AND ALSO JUST TO BE CAREFUL MY 1ST FANFIC THX :)

The seven, Calypso, Grover, Clarisse and Tyson all go to Hogwarts. They are sent to protect Harry Potter but he thinks they are only exchange students.

Kidnapped at the age of eight, Ashly Potter is the twin of Harry Potter, she's a daughter of Poisidion, she's favored by the Olympians, blessed by them too, she's joining Hogwarts for her sixth through seventh year, she might just catch the attention of a certain Grace at Camp. What will happen.

Percy, Annabeth, Jason, Piper, Hazel, Frank and Leo are all wizards/witches at Hogwarts.
