Do you go to the dungeon?

Svarku, the Efreet

An efreet calling himself Svarku lives in the central volcano of Anklis Island, overseeing a veritable army of imps, salamanders, and creatures of obsidian collectively known as the Fuegonauts. Svarku appears to control great wealth, which he uses for grand acts of narcissism and splendor. The actual operations generating this wealth are unclear, but seem focused on a certain type of red crystal found in the volcano. This crystal appears to contain flickering flames and glows softly in the dark, but appears perfectly mundane when subjected to all manner of arcane tests. Some evidence of mining is seen around the volcano, but nothing to indicate off-island transport, leading some to speculate that extraplanar portals may exist somewhere within the site.
