'Unusually colorful armor. Worn by the knight Jerren. Jerren preferred a nomadic existence, but after spending time as a guest of the Carian royals, he became a guest commander for General Radahn. And for the first time, the restless tumbleweed would be bound by honorable oath.' Jerren is the canon's most reluctant nobleman, an itinerant knight in motley colors who passed through the Carian royal court, befriended General Radahn, and accepted a guest-commander appointment at Redmane Castle out of honor for the first man whose company he could not casually outride. The armor he wears is a tumbleweed's: threadbare, pieced from a dozen passing seasons.

'A pointy, ragged hood. Worn by the knight Jerren. The hood hides an aged, bearded mask. Jerren served General Radahn as a guest commander, and they are said to have sworn an oath of honorable death to one another.' The oath is the canon's quietest blade. After the Shattering, when Radahn's body succumbed to scarlet rot and he wandered the Caelid wastes battling the heavens with the wreckage of his own mind, Jerren stayed at Redmane and organised the Radahn Festival, a tournament whose winner would have the right to give Radahn the death his oath had promised. Jerren also hunts Sellen, the Graven Witch and 'enemy of Caria,' as her declared executioner; it is the Tarnished, not Jerren, who chooses whether the witch lives or dies. He is the canon's stubbornest old man and its most reliable judge of last rites.
