Space prison

A prison in space where mortals and supernatural creatures, species from all over are abducted and locked up. The prison has a lot of security, so there's likely not a chance of escaping unless there was an army of people coming to save you. There are thousands of guards in the prison. The prison is in a big spaceship in space. Despite being locked up, it's not all bad as long as you don't escape. The cells you are in are prisoners big. The prisoners wear their own outfits and get to have their own things in their cells, but they can never leave the prison, and they are experimented with and researched by a species from a far away galaxy that serve a very powerful master that can absorb partial powers of other beings. Most of the people who are imprisoned probably didn't do anything, but they're still imprisoned.
