Gorotho

From the miasmas of Incarceron the upended spire of Mount Nadir rises, its flanks coated in an impassable layer of filth, but its interior honeycombed with passages where dark things live and breed.
The pit known as the Crawling Caverns winds its way through the rock of the mountain, ever in motion as the demons it breeds and shelters seek to bring about the destruction of the Absolute Citadel, the impregnable fortress which runs through the core of the mountain from bedrock to summit.
