him to sever his arm. However, his arm uses the remaining throwing star to impale him. While searching through the pyramid, Dameia discovers Quuhod's severed arm being eaten by maggots. One maggot grows to giant size and proceeds to sexually assault and kill Dameia. Back on the ship, Ranger catches sight of Captain Trantor running as if being attacked. Soon, Trantor spontaneously combusts as she fires a weapon in an airlock. Ranger races to save her, to no avail. After discovering Dameia's corpse, the other surviving crew head back to the ship. On the Quest, the ship's cook join the remaining survivors. The crew return to the pyramid. There, Baelon elects to stay behind and is torn apart by a monster. Meanwhile, inside the pyramid, Alluma, Ranger, and Cabren are separated by moving walls. Ranger begins to feel the terror effect, and is soon attacked by a double. He manages to fend the double off, regains control of himself while doing so, and the double fades away. Alluma is attacked by tentacles which crush her head. Rangers finds Cabren, the other remaining survivor, and tells him. Deep inside the pyramid, Cabren discovers that Kore is really the Master, who has been masquerading as Kore on board the Quest. He tells Cabren that he has "won the game." The pyramid turns out to be an ancient toy for the children of a long-extinct race, built to test their ability to control fear. Cabren is then forced to confront the creatures which the crew were attacked and also zombified versions of the dead crew, all of which he kills. Cabren states that he will not play this game, and will simply leave the planet. Kore's dying words express doubt that Cabren will be able to change his fate.
