Oncin: Hogwarts Simulator

Enter the Wizarding World. Study at Hogwarts. Live a life that was never written in the books.

Oncin: Hogwarts Simulator is a persistent, fan-made roleplaying simulator set in the world of Harry Potter. Attend classes, form friendships, investigate mysteries, or live quietly as the original story unfolds.

Play an original character, someone from canon, or a deliberately altered version of the world.

You do not have to become Harry Potter or follow his path.

Harry Potter: The World

In J. K. Rowling's seven novels, Harry discovers that he is a wizard and enters Hogwarts School of Witchcraft and Wizardry. What begins with lessons, friendships, and rivalries gradually becomes a struggle against Lord Voldemort that changes wizarding Britain.

In Oncin: Hogwarts Simulator, the world remembers canon without requiring you to reenact it.
