Winds of Darkover

Turning under a blood-red sun, Darkover had always been a mystery to the Terrans. Its most puzzling riddles lay in the incredibly high mountains known as the Hellers. These jagged and almost impassable peaks sheltered races and enigmas that had become legend in the outside world--the howling inhuman Ya-men, the deadly Ghost Wind, the fiefs of barbaric brigand chieftains, decaying eldritch Dry-Towns...and the eerie forces that were worshiped as gods.
