The Age of Worms
Former battlemage at Blackwall Keep. He returned from a peaceful mission to treat with the Twisted Branch tribe of lizardfolk ill and demented. His convoy of five soldiers were dead and he was dazed, raving, and in an ice-cold fever. Archie attempted to nurse him back to health but after three days he died, and rose again as a Spawn of Kyuss, a victim of the slow worms. He drove all in sight mad with fear and infected four soldiers before Commander Garm boarded him up in an abandoned escape tunnel, where he remained for two years. Now he has been set free and turned others into spawn like himself. Walker hails from a powerful and vengeful family in Greyhawk who were told he had merely wandered away from the Keep one day and never returned. The party learned from Hishka that Walker had treated alone with Illthain before returning to the Keep.
