The name for the creatures of the planet Zarr. A fanatical, ruthless race who conquered most of their galaxy, Xentilx. The god Zathog made a pact with the Zarr, granting them the power to travel through time and space, and thus conquer all the Universe if they actively sought to free the Great Old Ones, and oppose the Elder Gods. There are references to “the Zarrians” in The Black Book of the Skull which is an alternative term for the Zarr. Their method of conquest is to subdue the planet with nuclear bombardments, then capture samples of the planet's inhabitants to form a pupet government and overthrow any internal opposition.
The novel The Winds of Zarr, by Richard L. Tierney, details Zarr.
