A nobleman has disappeared, and the town is danger of being attacked by nomadic creatures called kra-dhan. To help the town, the heroes travel through narrow, icy ravines to a druidic circle of stone known as the Talons of the Horned King, which is believed to be the source of the town's problems. There they discover a sinister tribe of kra-dhan - and the ruins of a spaceship buried beneath the Talons!
