Caith rides Dubhain back to Dun Glas to free Nuallan. Once again Dubhain is weakened by the witch's spells and Caith has to enter the keep on his own. He sees Nuallan helpless in his cell, but Nuallan asks him to unlock it with the silver key Caith unknowingly still had all this time, the key that would have given Moragacht access to Faery. Nuallan takes the key and flees the keep, leaving Caith to fend for himself. Moragacht, furious at the loss of the Sidhe, prepares to deal with Caith, but he throws the charred piece of wood Firinne gave him into the fireplace which releases Padraic, the ghost from the hilltop fortress. In an act of revenge, it begins destroying Dun Glas and all in it. With the witch's spell now diminishing, Dubhain rescues Caith from the keep, while in the loch a whale from the sea turns on the beast. The shadow over Faery lifts and Caith and Dubhain resume their travels.
