With the help of Ephebe's Great Library, and the philosophers Didactylos, his nephew, Urn, and Abraxas, Om learns that Brutha is the only one left who believes in him. All others either just fear the Quisition's wrath or go along with the church out of habit. While in Ephebe, Brutha's memory aids an Omnian raid through the Labyrinth guarding the Tyrant's palace. While in the library of Ephebe, Brutha also memorizes many scrolls in order to protect Ephebeian knowledge as Didactylos sets fire to the building, to stop Vorbis reading the scrolls there. Completely unrelated to the story, the Librarian of the Unseen University travels through L-Space to rescue several of the abandoned scrolls.
