CastleRock exists on a far planet called Psion Moon. There was only one way on, and one way off... Anyone trying to escape was killled on sight. The "Rock" as it's called contained 3000 inmates below the huge castle's floors. All were on death row waiting to die for their crimes. A deal was made for Liandri to step in and revamp the facility to not only produce molten, but also give the inmates a choice to fight for their freedom by playing the Tournament. The only catch was... If you won, you lived! If you lost... well, then you die!
