Lord Kelnor, Earl of Drumer

Lord Kelnor, the Earl of Drumer is the central antagonist of the Fighting Fantasy gamebook House of Hell (renamed House of Hades in the U.S.A); a horror-themed gamebook notable for taking place in modern-day earth instead of the Fantasy world of Titan. He first appears as the wealthy aristocrat offering shelter to the playable character, but he is soon revealed to be the head of a devil-worshipping cult that must be taken down.
