TOWER of BLOOD!
Conan and Red Sonja are being chased by bounty hunters after leaving the city of Arenjun with a suspicion of a murder charge hanging over their heads. An arrow topples Sonja's mount, and Conan scoops her up as they make their way into a rocky, mountainous pass. They are forced to abandon their other horse as they reach a cavern in the cliffs and Conan takes advantage of a loose boulder to topple on the pursuing bounty hunter, killing all but their leader, Mamnon, who flees to get more help. The two wander into the gigantic, red-misted cavern and are attacked by a humanoid bat creature. They find a structure at the center of the fog, but are mystically attacked and rendered unconscious. Conan awakes first, to face Uathacht and her brother Morophla, immortal vampires cursed by Thoth-Amon, while the bat-creatures outside are creations called Afterlings. Morophla seems to have full power of Conan's actions, and forces him to carry Sonja to Dromek, a hideous creature who was used as a breeder for the brother and sister's food supply, but has since devolved into a monster. Uathacht pushes Sonja into Dromek's pit, but Conan jumps in and slays the creature. Conan and Sonja are brought to a cell where they await their fate.
