Goulnax was a Svirfneblin leader of the Second Epoch. When he became an undead servant of Thasmudyan, he had built the unhallow halls of Izurâg.
When they were adventurers, Crimson Eye went into Tarâks Burrow and found their way to the Tomb of Goulnax. They made off with great riches and discovered a pair of mechanical elevators that descend down a mile or more where they reach a passage that ends in Shiz-Abscis sewers.
