Wern was a shaman appearing in The Fiery Moon, the sixth part of Heroes Chronicles. He was the wisest of Tarnum's shamans. Tarnum and the barbarian tribe under his command were trying to follow Vorr, the Mad Ancestor who had captured the other Ancestors and tried to destroy the World Tree. Tarnum asked Wern where Vorr could have gone, and gave him a ceramic bottle full of strong spirits as payment for his services. Wern drank the bottle, but when Tarnum returned a few days later for the answer, the shaman had forgotten the question. When Wern tried to scam another keg of ale out of him, Tarnum grabbed him by the throat until the shaman admitted that without the guidance of the Ancestors, he could tell him nothing.
