" There is one universe, by the definition of universe. It is not the cosmos we see through our eyes and our telescopes—that is but a single Narrative, a thread winding through a Hemn space shared by many other Narratives besides ours. Each Narrative looks like a cosmos alone, to any consciousness that partakes of it. The Geometers came from other Narratives—until they came here, and joined ours. "
