Gûman-Khâl Sodlund

In the Horgon Era, Gûman-Khâl was called Sodlund by its Glangveif builders. It was a small outpost built to house a group of warlocks studying Onaidreds Quill. Faced by a huge army of hobgoblins, they powered up this artifact, freezing the army and creating the unnatural glacier Nym-Zoedine. A town grew up here from all the slaves sent down to mine the glacier in search of bodies said to be laden with plunder, but importantly to find the artifact lost in the ice.

After the fall of Glangveif, Sodlund was abandoned to the wilds.

In the First Epoch, Umahanbad took possession of this Underdark ruin and began rebuilding it. They too learned of the area's hidden artifact and have put a good amount of resources into searching for it.
