The Empty Book is the fourteenth chapter of The Castle of Llyr. The middle section of the story comes to a close as the third act begins. The mystery of the magical items already introduced deepens, the themes of friendship and cooperation thicken, and a major protagonist reappears with word of the villain.
PlotPrincess Eilonwy's bauble, held by Prince Rhun, blinded the giant Glew. The enraged Glew's shouts and moans inadvertently opened up fissures in the cave ceiling, knocking the giant out cold with a stalactite and helping the Companions escape from underground. To Taran's annoyance, Rhun insisted on going back to the cave to fetch the empty book the group had found in Glew's hut; by the light of the bauble writing appeared on the previously blank pages. When the companions reached the rocky mouth of River Alaw on their reconstructed raft, they met Gwydion who told them to "Keep to the shadows" for "Achren's eyes are sharp."
