Thork was a fang of Yeenoghu from a footwear-looting gnoll tribe of the Eastern Shaar. When adventurers slaughtered his gorger and most of his tribe, he surrendered, hoping the heroes would be able to defeat the demonic scourge, Afoot. He also gave information that Ernil and Kalimac had been sold to the Meatmonger. Unwilling to enter Crescent Valley himself, he was left to guard the horses. He escaped while the adventurers fought his master.
