Zarrak was an Ewok from the moon of Endor and was a member of the tribe that inhabited Bright Tree Village. As a young Ewok, he was discovered to have magical abilities and was taken as the Shaman Logray's first apprentice. During his lessons under Logray, Zarrak was impatient and wished to learn greater magics, including the dark arts. Despite his master's warnings, Zarrak attempted to steal the tribe's powerful totem, the Sunstar. When he was caught, Chief Chirpa was forced to banish Zarrak for his actions. Zarrak took up residence in mountain near Bright Tree Village, and began to delve into evil magic, mastering the arts of telekinesis and transformation. During his exile, Zarrak had designs to conquer Endor, and he accessed a prophecy pool to determine whether anyone could defeat him.
