The Obsidian Spire
Dwarf cleric of Moradin, sent to Ryjum Pass to prospect for a mithril mine by the High King of Hammer's Hope.
Drokan’s treachery was revealed upon returning to the Keep on the Borderlands and the heroes interrogated him. The dwarf confessed to working with someone within the keep and voluntarily agreed to be possessed by the shadow entity called Kroll, in exchange for gaining power to overthrow the dwarf High King of Hammer’s Hope. Drokan was imprisoned in the dungeons below the keep but was killed when a strong earthquake collapsed his cell.
