Deadstan

Deadstan is a strange-looking planet in Magna's Galaxy which ins unhabited and has no chance of hosting life of any kind, as it is said to be virtually impossible to terraform. The ground is made out of a some kind of mixture of mud and a poisonous acid fluid. The rivers are made out of the same fluid, but it appears to be twice as acid. There are no lifeforms on the surface, although some expeditions (failed) have been made to discover if there was any life underground. Some scientists theorize that there may be life underground, although it is no more complex than fungi.

Underground
It is theorized that there may be life underground and also some precious and exotic ores. Several expeditions were sent there, but the harsh and acid atmosphere and the acid ground made impossible to venture that, even by the use of robotic creatures. The Centinids and the Mi-Go have tried to get there, but failed miserably.
