Woundwort discovers that a human construction crew plans to bulldoze Redstone. He and Vervain travel to the Warren of the Shining Wire where he tells Cowslip he will show him Redstone destroyed if Cowslip will give him his seer, Silverweed. Meanwhile, Hickory and Flax talk of revolt against "Weedstalk" while Marigold races to Watership Down to warn Hazel and the others of Woundwort's return. The wandering Campion stumbles across a new warren, Darkhaven, populated by savage rabbits who await the prophesized return of "the Dark One." He becomes their chief after he defeats their strongest warrior, Granite, winning the respect of a tough doe named Spartina.
