Wart was a sworn brother of the Black Company mentioned briefly in Water Sleeps. He played a minor role when the Company subdued a group of about 50 Protectorate-aligned Shadowlanders who had trudged out of "New Town" (Kiaulune) to confront them. The event occurred without bloodshed, and Sleepy (the Annalist and ranking Company officer at the time), recalled that it was probably Spiff or Wart who remembered to make their new captives temporarily lie down on their bellies after they turned over their weapons. The highest-ranking captive, Suvrin, would go on to become the Company's leader in subsequent years; the others were set free. Other Company members and allies who were present with Sleepy, Wart, and Spiff during this event were Goblin, Tobo, Ky Sahra, and Uncle Doj.
Wart was probably a veteran of the Kiaulune wars that occurred during the first 5 years of the 15-year-gap between She Is the Darkness and Water Sleeps.
Wart was not mentioned again after his appearance outside New Town. He almost certainly joined the rest of the Company as they passed through the Shadowgate, crossed the glittering plain, rescued the first set of 5 Captured from the cave of the ancients, and finally entered the strange new world of Hsien.
