Rellnas Minor, a satellite orbiting Rellnas, presented a diverse array of ecological zones. However, the indigenous Rellarin population primarily resided in settlements along the coasts and islands of its extremely cold polar areas.
The Rellarin civilization was characterized by a rudimentary, stone-age level of technology, and they seldom ventured beyond their planet. Rellnas Minor's sole export consisted of the insights and knowledge possessed by the Rellarin tribal leaders, known as un'Yala. These wise individuals held significant esteem beyond their world, particularly among the Swaze inhabitants of the Jidlor system. The Swaze made it a tradition to dispatch their leading figures annually for consultations with the un'Yala.
Around the year 19 ABY, an un'Yala named Moshene Tre departed from Rellnas Minor and assumed the role of a New Republic Observer.
