Mount Thargill

Mount Thargill was an extinct volcano and the easternmost peak of the Starspire Mountains in Tethyr.

The ancient lava tube of Mt. Thargill was known as the Wyrmwell. It and the tunnels around it were used as one of the lairs for the red wyrm Balagos and as prisons for the brown dragon Altagos and the black dragon Auroxas.
