Goulnax, a prominent Svirfneblin leader during the Second Epoch, constructed the hallowed halls of Izurâg, where he would ultimately find his eternal repose.
When they were adventurers, the Crimson Eye group ventured into Tarâks Burrow and discovered their path to the Tomb of Goulnaxb. They departed with substantial riches and uncovered a pair of mechanical elevators that descend a mile or more, leading them to a passage that terminates in the sewers of Shiz-Abscis.
