Treestump is the oldest living Wolfrider and chief of the Wolfriders when Cutter is absent. His original name, Birdcall, was changed by Bearclaw when he watched his friend stand like an "ol' tree stump" during a troll ambush. Seemingly gruff and no-nonsense, he has a vulnerable side, especially when it comes to protecting his tribe. More than a thousand years of living with "the Way" has given Treestump a well of wisdom, allowing him calm even in the face of great danger. He is something of a father figure to the entire tribe.
Treestump was Recognized to Rillfisher, with whom he had his daughter, Dewshine. As often happens with a Recognized couple, Treestump was consumed by grief when Rillfisher was killed by a falling branch. This early loss has made Treestump even more fiercely protective of the family he has left; he finds it hard to wait when those he loves are in danger. Clearbrook, another tribal elder and one who understands a lifemate's loss, has gradually come to fill the empty spaces in Treestump's life left by Rillfisher's death. It took time, patience and healing - and the release of One-Eye's spirit - to leave the way open for this new relationship.
