The Forgotten Realms [Fan Version]

The Great Worm Cavern is a sacred site for the Great Worm tribe of Uthgardt barbarians, located in the Valley of Khedrun within the Spine of the World mountains. This vast underground complex features tunnels leading to the Underdark, including the fabled Gauntlgrym, and houses an altar mound shaped like a spiraling winged snake, symbolizing the Great Worm totem.

The cavern is expansive, with high ceilings adorned with bioluminescent fungi casting an eerie glow. The altar mound, resembling a great winged snake, dominates the central chamber, surrounded by tribal markings and offerings from the tribe.
