From Introduction: The wailing willow is indistinguishable from a normal weeping willow tree; however, it constantly produces a sorrowful wail. Wailing willows are animate trees that have developed a unique survival tactic. Creatures who hear its song feel an overwhelming sense of despair and simply want to lie down and cry. Those who succumb often starve to death and eventually decompose, thus enriching the soil around the tree with nutrients.
