Researcher Haversham is one of the Legacy Chain scholars who has a lot of information on Calistyx the Shaper. He can be found during the mission Force information on Calystix from the Legacy Chain from Diviner Maros (CoV, Levels 25 - 29), and he must be kidnapped and taken to the library. Researcher Haversham has almost the same hit points as a Lieutenant of the same level and no attacks at all. Once you have captured him, three waves of Legacy Chain mystics will try to free him.
