The Frostrivers tribe dwells along the Great Frozen River. Its members live in harmony with Nature. The tribe obeys the laws of the Four Elders, themselves guided by the most venerable of the Elders, the Neta-Tanka. When the Neta-Tanka enters the twilight of life, the Frostrivers gather at the Sacred Grounds to designate a successor. During this ceremony, each clan presents a young leader who will need to demonstrate generosity and the ability to provide for the tribe in order to become the new Neta-Tanka.
