Jonas Hambleton was the secondary human antagonist of the adventure video-game, Call of Cthulhu - Shadow of the Comet and the primary source of evil within the story outside the Great Old Ones and Narackamous. Believed dead for many years Jonas had in fact become an ascended cultist living deep underground and bestowed with Lovecraftian powers in exchange for his untiring services to the Great Old Ones - his crimes were great and numerous but perhaps one of the most terrible was his first.
