The vast and impenetrable desert of sands of obsidian glass, tractless and ever-shifting. Bathed in the twilight of the Lighted, the region is like that of a realm wholly alien with only the promise of death.
The region is marked only by the ebonglass sand that has over millennia worn away any formation, natural or created. Any winds that drive the sands or at worst a true storm, is a deadly occurrence as the glass sand flays the flesh.
There is no knowable path or guiding sights within the Obsidian Abyss, only the eclipsed brilliance of the Lighted that is absorbed into the sands.
No settlement has yet been sustained in the Obsidian Abyss. Only the careful migration of wandering Kagyr human tribes and the seasonal outposts of the Arkyme dare to call the region home.
Beneath the Obsidian Abyss is the festering womb of eldritch corruption known as the Buried Kingdom. To even reflect upon what might lie in the deepest recesses beneath the sands is to believe in impossible horror.
