Whilst training under Grey Seer Skraw, Klawmunkast lost his left eye in a warpstone explosion in his master's lab. When Skraw was killed during an attack on the Empire town of Wissenberg, Klawmunkast recovered the old Skaven's body, extracting the warpstone charm that Skraw had in place of his own right eye and placing it inside his own empty socket. The Eye is a potent talisman and radiates disharmony and hostility, as well as projecting a baleful gaze.
