The shadow realm gained control over the past world, whose power of spirit, blood and nature was hidden in the crystals. The last rulers of the past created Assassins who were sent to defeat the Keepers of the crystals and get their power back. Upon entering the realm, they were exposed and forced to fight against each other in the Arena not only for own survival, but also for the survival of their world, to which they can no longer return.
