Pomoyk, kherigan term for big house, is a supermax prison complex located on the island of Zesdrey in the eastern sea on Rigel. It houses "ransom" criminals from all over the galaxy.
Pomoyk operates on the principle of taking in prisoners from other worlds in the galaxy when their own governments do not want to deal with them. The prison receives constant payments to keep them locked up.
In certain cases, the prison can accept third party payments to release or execute individual prisoners.
