Heinrich Marsteen was a lieutenant in the guard of Gryphon’s Bluff, second in command only to Wilton. Heinrich became involved in a plot to murder the central authority figures in the city, and was succesful in seeing the Mayor Hagland assassinated. His efforts to kill Wilton and High Priestess Idira Leafdancer failed however. As his plot was thwarted, it was learned that he was in league with the Serpent Lord, as was his daughter. Unlike Darius McShane; however, both Heinrich and his daughter Meg were willing consipirators.
Heinrich was summarily executed for his crimes, but his daughter remains at large.
