Obeliskian Servitor

A mysterious floating creature, created by the death of a Cultist. In appearance, a floating, black six-sided cube with four glowing green eyes and trailing tentacles. Very tough opponents, Obeliskians are armoured, and possess much greater health than Fishmen or wildlife. They will pursue your colonists and attack them with their tentacles. Slain Obeliskian Servitors may be butchered to yield up stone blocks.
