Shaman

A shaman, also known as a medicine man, was a member of certain traditional societies who acted as a medium between the physical world and an invisible spirit world and who practiced "magic." Among the Ewoks of Endor, the rituals performed by the shamans like Logray were meant to ensure their tribes remained in harmony with the forest spirits. The Nightsisters of Dathomir also had their shamans.

A'Yark's tribe of Tusken Raiders believed Jedi Master Obi-Wan Kenobi, who lived within the Western Dune Sea and remained on the planet Tatooine as part of his exile, was a shaman who lurked in the canyons. Eventually, the young Tusken A'Koba decided the tribe needed to marshal its members together to finally hunt down the supposed shaman, unaware of how he was leaving the planet with Luke Skywalker during the same time.
