Corrupted Parts

The Corrupted Parts are relics from a parallel universe and are the limbs of the dead players in another world. When Omega was destoryed space and time was warped causing a gateway between two worlds to appear. In this other world the Ujains lost the battle agaist Omega and were destroyed, aside from a few survivors who come to this world.

For a while the Ujains believed the damage in time and space was causing the virus and not the Stone. These bits of chunk which made it to earth were said to be the reason the PK gained tech so quickly using the energy left behind from Omega to craft powerful weaponary and tanks.
