The sheriff travels to Fairwater Lake to examine the remains of a prize bull and finds some surprising tracks at the scene. The search culminates in a deadly fight on a boat.
Driggett and Leana are escorted to a Supreme Council meeting in Stonehaven Hall. Ambitious Gazer Stonemaker tells of a terrifying invasion of Rockworld by creatures identified only as the Kanan . Driggett is needed to locate and utilize the prime pyrite crystal, regarded as the single weapon that might save the Nehwisna. A small band sets out on a nearly impossible quest to find the weapon.
Gregory is reunited with Driggett, but the expedition has proved deadly and only a handful of the original force remain, together with Arak, a half human whose motives remain unclear. Valea succumbs to the Kanan in battle and lies lifeless in Gregory's arms. Only one thing can save her, and its use remains illusive.
