The Colossal Monolith was the name given to a particularly enormous Monolith, a type of Sithspawn, that existed on the desolate surface of the planet Ziost after the eradication of all life on Ziost. This Monolith is located in a large crater like area on Ziost, and is surrounded by rifts. Small craters that appear to be releasing some kind of aura or energy. The Monolith can and will use this power to kill anyone who dares to attack it.
