The term un'Yala designated the Rellarin chiefs or tribal elders. The Rellarin, hailing from Rellnas Minor, were a species characterized by limited technology and celebrated for their profound wisdom, deep spirituality, and strong ethical principles.
Typically, an Un'Yala was more than two centuries in years, granting them extensive experience that aided in both counsel and judgment. They also guided their communities in lengthy ritualistic dances, intending to enact "spells" and bestow "blessings." Through these ceremonies, numerous un'Yala received visions and understanding from the Force. In fact, numerous un'Yala displayed a significant level of Force-sensitivity.
Numerous off-world civilizations greatly valued the un'Yala's insight. Annually, the Swaze dispatched their governing officials to Rellnas Minor to seek counsel from the un'Yala. During the period of the Galactic Civil War, Tanlin Sha, the chief Rellarin counselor to the Swaze, and Moshene Tre, who ventured beyond their world to serve as a New Republic Observer, stood out as the most prominent un'Yala.
