Cykranosh

Cykranosh is the name of the planet Saturn in the Hyperborean language. This planet is inhabited by many gods and races, most portrayed in the Clark Ashton Smith story "The Gate to Saturn." The planets inhabitants include the Spawn of Tsathoggua, many of Tsathoggua's family, and various lesser races.

In "Through the Gates of the Silver Key" HP Lovecraft hints that the planet is inhabited by a race of white fungi-like creatures.
