Hellmouth

The Hellmouth is a location on the Moon. Inhabited 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.

The Hellmouth's many underground passages reach far and deep into the Moon; besides the main entrance through the gatehouse, it also has tunnels connected to the Temple of Crota, Archer's Line, and Anchor of Light. Within the Hellmouth itself is a labyrinth of chambers for various purposes; The World's Grave, containing the Hive's collective knowledge, the Chamber of Night, where the Hive perform profane rituals, the Summoning Pits where Phogoth is kept chained, the Shrine of Oryx where the Hive contact their gods. But in the deepest, darkest pit in the Hellmouth is the Fortress of Crota, Son of Oryx.

The outer surface of the Hellmouth covers a wide area, including a platform overlooking the pit and a small moonbase hidden away in the rocks. Public Events, resource nodes, and patrol beacons can only be found on the surface of the Hellmouth, not within.

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.
