Hellmouth

The Hellmouth is a location on Luna. Constructed by the Hive, it is a fortress cored deep within the moon. The Hellmouth features an inner sanctum, gatehouse, and dungeons that are located in the depths of the fortress, imprisoning the Hive's most fearsome denizens.

Trivia
From a design standpoint, the Hellmouth is meant to evoke feelings of scale, menace, mystery, darkness, evil, strength, militarism, and the exotic without coming across as being too alien. Its imagery is meant to invoke feelings of Medieval/Gothic architecture.
