When a fourth name emerges from the Goblet of Fire, it is not Harry Potter who is thrust into the Triwizard Tournament. Instead, it is his long-missing twin, Helen. She comes to Hogwarts to compete, and with her comes a magical world—and legacy—unknown to her brother. For Helen is more than just his twin—she is a half-blood.

Read as Percy and the rest of the seven complete their journey through Hogwarts. AU. Percabeth, Jasper, Frazel, Caleo and Solangelo.

If you're Percy jacskon life is hard.

A person's destiny is never set in stone, Harry now knows that better than anyone. After all, his destiny has been completely turned on its head by the actions of both his mother and a capricious goddess. Whether this is for good or bad is yet to be seen, either way Harry's life has been set on a new course, and he for one could not be happier about it.

Years after the final battle of Hogwarts, Harry, after leaving the British Isles behind, once again finds himself in an incredibly dangerous situation. while galvinating about in his animagus form, accidentally finds himself adopted by Artemis and Her Hunters! Now, he must keep his cover, lest he be discovered and killed. (Now looking for Beta, PM me if you're interested).

Looking back it might not have been wise to invite the most powerful demigods in centuries into one magic school. Sets place during The Order of the Phoenix and after Blood of Olympus. Trials of Apollo do not exist here.

She missed him. So badly. They needed help. So badly. Two worlds collide. But will both survive the eccounter?

Sorry I am rubbish at summaries, basically Harry Potter is taken by two higher beings and is then sent to different universes and times to keep the balance between light and dark stable, eventually he winds up being born in Sparta (yes, that Sparta but he wont be wearing nappies and kicking people down holes) and he confronts demi gods, monsters and a certain goddess

For Percy Jackson, life was good. No more wars, a great family, and the gods weren't blaming him for anything he didn't do. But all of that changes when he finds himself as some other kid, with some hairy guy claiming Percy's name is Harry Potter, and he's a wizard. (ABANDONED, UP FOR ADOPTION. PM FOR DETAILS)

Random one-shot inspired by a moment in Philosopher's stone (not Sorcerer's).

The 7 demigods, Reyna, and Nico di Angelo are sent to a different world. The 9 are on a quest to bring Harry Potter, Hermoine Granger, and Ron Weasley. However, things get sidetracked. "Why did there have to be wizards?" Nico asked. Three wands were pointing at him.

Dos mundos que se entrecruzan más de lo que parece; uno de ellos olvidado por la mayoría del otro. Una profecía mal interpretada. Y un joven , que deberá descubrir su misión antes de culminarla. Harry es un semidiós pero al mismo tiempo un lejano legado de otro por parte de padre.

Cel hasn't been in the Wizarding World for 14 years. She was happy with where she was and didn't want to go back. What happens when she must go back with her sisters to get rid of the resident Dark Lord? [CURRENTLY BEING REWRITTEN]

Nico faces challenges and secrets with his friends at Hogwarts. Includes: Solangelo, Frazel, FeirroChase, Sam/Amir, Sanubis, Carter/Zia and OC/OC

The Heroine of Olympus has many titles, titles that would make anyone envious. She is strong brave and loyal to a fault. Follow her journey as she enters an entirely different world- of wizards and magic. Will she have to be the leader again? read to find out. (sorry for the horrible summary I am better at writing longer text.) T rated for occasional violence and triggers.

The Greek Gods aren't the only weird thing about Percy's family. No. Apparently his mother's family are magical. Apparently his name is technically Perseus Black.

Sophy Alkaev-Shaderock has found a steady new life studying at Hogwarts alongside Harry Potter and his friends. When a strange incident brings a team of strangers to the Hogwarts grounds, Sophy is pulled, head over heels, into an extraordinary new world. Can Sophy balance the growing weight of two unique worlds and find the courage to face her turbulent past at the same time?

Sally Jackson hadn't heard from her cousins for a while. Actually forgotten about them, in fact. She never expected to see one on the news, or the trip to England.

When the big wigs of the universe have to kick your ass down a snow bank into a parallel reality just to put someone in your life, it's not always a good thing, trust me. Jack may have broke his crown, but Jill came tumbling after. That dumb bitch.

Nico was hoping for a year free of monsters and evil great grandmother goddesses trying to destroy the entire Earth. Unfortunately, a new threat is rising, this time in Britian. It's up to him to stop an evil overlord from taking over the magical world. (This is my first attempt at writing a fanfiction!)

When the seven from the Prophecy went to Hogwarts to learn and to teach
