Without Timmain's Sacrifice, the Wolfriders would not exist. In her son's own words, here is a piece of the story he told the night he passed the chief's lock to his daughter, Rahnee the She-Wolf, as found in The Blood of Ten Chiefs - Volume One, "Coming of Age".
**I have led you all for many twists of moons and seasons. Many, elf and hunt alike, do not recall the times before when Timmain made her sacrifice and went to dwell among the true-wolves. She went to save her people, to bring the strength and cunning of the true-wolves to those whose memories held only gentleness.**
**She could do nothing for those already born; she meant her sacrifice to benefit their children. She sent me, her child, to teach her people to hunt, to move them safely from the land of long winters, and to insure that her sacrifice was given to the children.**
**I have failed,** Yellow-Eyes howled, filled with his mother's despair. **Her people do not hunt and do not have children. My children see only each other and chafe to be free of their weaker, elfin kin--and I grow old. I can no longer hold my family together, so I shall let it fall asunder and pass my spear to the strongest of my first-born.**
Within the Wolfrider tribe, the chieftainship is passed from parent to eldest surviving child. Sometimes, this does not always hold true as the eldest surviving child is not always suited for the chief's lock. In the case of Rahnee the She-Wolf, she was not the eldest, but she held within her an inner strength that Timmorn Yellow-Eyes recognized and honored by passing the spear to her. Though she was not the highest among his children, she had the qualities of a chief hidden within. The secret of Timmorn Yellow-Eyes and his children was "an unconscious majesty that drew the eye without effort." Rahnee possessed it.
Cat was not given the lock by her mother, Rahnee the She-Wolf because she departed from the original tribe long before the She-Wolf's chieftainship came to an end. Recognizing her for the chief's daughter she was, Cat's followers entreated her to let them tie the chief's lock in her hair. After Cat, the lock was passed to her daughter, Shadow-Wolf, who was her youngest but also the only surviving child. Shadow-Wolf has two children: Wolfgrin and Scarletwisp. Only time will tell which cub will inherit the lock.
