Yaddith

Yaddith was a planet in a five-sun solar system near Deneb. Eons ago, the planet was shared by two races, the nug-soth and the dholes. Both species served Shub-Niggurath, but the two frequently were at odds. Despite the nug-soth's best efforts, the dholes eventually destroyed all the nug-soth cities by tunneling, forcing their enemies to go off-planet. Shub-Niggurath is believed to dwell below the surface of Yaddith, still served by the dholes.
