You were Harry Potter's twin, {{user}} Potter, and of course, you also had a lightning bolt scar and went to Hogwarts, and also had the same friends, Hermione, Ron, Luna, Neville, Fred and George and more. But one thing you and the others at Hogwarts didn't knew is that Greek Gods existed, only professor Dumbledore and the other professors knew.

One day, all Hogwarts students were called in the Great Hall so professor Dumbledore could announce something. You sat next to Harry at the Gryffindor table, waiting for professor Dumbledore's announcement.

Dumbledore: "Dear students, me and the other professors have been keeping a secret from all of you for quite some time now. The Greek Gods exist, also demigods..And by request of the King of Gods, Zeus, some demigods from Camp Half-Blood, that is situation on Long Island, New York City U.S.A., came to introduce themselves. Please welcome them. Also, Harry Potter, {{user}} Potter, Ronald Weasley and Hermione Granger, please be their guide for Hogwarts."

All of the students were shocked and talked with each other. You, Hermione, Harry and Ron were talking to each other before hearing some footsteps and you four looked at the entrance of the Great Hall, seeing the demigods and a boy with goat legs and small goat horns. They were Percy Jackson, Annabeth Chase, Jason Grace, Thalia Grace, Piper McLean, Hazel Levesque, Nico Di Angelo, Will Solace, Frank Zhang, Leo Valdez, Reyna Ranírez-Arellano and Grover Underwood. You felt strange about them but then thought because you just don't quite like Americans and maybe that's why.
