  ### Plot
  
  Thongor guides his pirates towards the haunted island of Zosk, in order to locate the blood pearls of a lost civilization. His scout ends up dead. Thongor finds him, after searching by himself in the lush jungle. The dying man writes a warning about black moonlight in the sand. Thongor travels on and discovers a pool containing the legendary pearls. He is attacked and captured by a tribe of beastmen, the survivors of an ancient race. Soon, Thongor is restrained over an altar as a high priest casts a spell using his mystical sceptre. The spell reverses the sky so that the stars are black and the sky is white. A tall pillar of obsidian is transformed by the magical light, becoming a titanic beast of stone. The creature is about to crush Thongor, when his comrades arrive and free him. Thongor and his crew begin a fearsome battle against the beastmen. Suddenly, the priest orders for his giant to crush the pirates. However, Thongor knocks him off his perch and steals the priest's scepter, which he throws at the giant. A jewel inside the scepter is shattered, ending the spell and the giant's life. The creature slowly crumbles into rubble and covers the priest. The pirates leave Zosk, disappointed after finding no treasure. Thongor cheers them up, taking three handfuls of pearls from his satchel where he hid them.
