Nishrek

Nishrek was a Fiendish plane in the World Tree cosmology model and later an astral dominion in the World Axis cosmology model. Prior to its attachment to the World Tree, it was Gruumsh's realm in Acheron, occupying one face of a gigantic cube (and then later, the whole cube ) as described by the Great Wheel cosmology model. Nishrek was the last known home of the orc pantheon,  which tended to wander or be forced out of various previous homes.
