Flautherland

Flautherland is a prison located in the great void in between universes. Its name comes from a word in a lenguage long since forgotten, which means 'Freedom.' The people in charge of the prison collect criminals from all over the multiverse to drop them off here. They also gather incredibly dangerous creatures, which could easily destroy entire planets. Nobody knows why its here, or why. And no escape attempt has ever been succesful. The director leeps refusing to answer questions, and homes himself in the highest floor of the building. Currently, the prison is empty and abandoned, and its prisoners rehomed in random universes. Something happened it the past that forced it to close down. But the prisoners still remember their time there, and they remember the horrible creatures that called themselves guards.
In regards to organization, the main characters come first, then the prison guards, then other very important characters, then everyone else.
