With the five Sacred Horns collected, the patrol heads west to face the Destroyer of Ferndale. When they arrive in Barkstone, they meet with Elymis and Seyth. Seyth, grateful for the kindness they showed him in Grasslake, tells that he has discovered the names of Folker’s conspirators. He also reveals that Folker has been sending secret patrols across the scent border to lure the beast into attacking the weasels. Elymis tells them that Folker has returned to Lockhaven, where he plans to assassinate the Matriarch while his army crushes the weasels. While deciding which matter to attend to, the four young hares the patrol aided in the spring arrive to give them a ride. Garrow orders the army to protect the weasels, while the patrol rides against the Destroyer and uses the Sacred Horns to drive the beast away. With no time to rest, they immediately ride back out for Lockhaven, arriving just in time stop the assassin and arrest Folker.
