Androzani Minor

Androzani Minor is a dry, sandy planet close to Androzani Major. Androzani Minor is a desert planet, with its ocean dried up for billions of years. Due to the unusual composition of the planet, boiling hot mud flows throughout the planet's crust, blasting its way to the surface in dangerous explosions. There are series of caves carved out of the rock by the mud, some of which lack oxygen.

Despite the conditions of the planet, there are still some forms of life, such as the Spectrox Bats and the Magma Beasts. Humans also came to planet, mainly to gather the Spectrox found in the caves. (DW: The Caves of Androzani)
