Thorbjorn was a formidable Werebear warrior who lived an isolated life within The Stillwoods before being pulled into an astral arena to fight the adventurer Kairus. Instead becoming close friends and allies over a period of months, Thorbjorn later joined the Brass Tribe and aided in training the tribesmen for a time. Traveling with his lifelong friend Kairus to the Promythean, Thorbjorn was ultimately cut in half by the fiery whip of Baphomet's avatar.
