The Caves of Delmarin are located deep beneath the Halls of Blackrock. They are inhabited by a race of snake-like creatures called the Dyissans who are led by Taralis, their evil queen with the assistance of Sanas, the Chosen. The Dyissans greatly dislike outsiders and will attack if provoked. In a stale living area in the upper elevations of the caves, the dwarf Brignal Rockgrinder has made a home for himself.
