Born realizes that the newcomers are on his world to gain a life-extending drug from the burls formed by the They-Who-Keep trees around buried people. Horrified by this discovery and the invaders' callousness toward living beings, he uses native plants and animals to destroy their station. In the final fight Losting is killed, but Born returns to the Home Tree. Losting's brain and mind are absorbed to form part of a developing planet-wide network of consciousness involving They-Who-Keep and the furcots.
