Atrus writes a new Age called Releeshahn for the D'ni survivors to rebuild their civilization as he and Catherine settle back on Earth, raising a daughter named Yeesha. As Atrus prepares to take the Stranger to Releeshahn, a mysterious man named Saavedro appears and steals the Releeshahn Descriptive Book. The Stranger follows Saavedro through several Ages (which were used to train Sirrus and Achenar in the art of writing Ages) before finally recovering the book. Ten years later, Atrus asks for the Stranger's help in determining if his sons have repented after their lengthy imprisonment; the Stranger saves Yeesha from Sirrus's machinations, but Sirrus and a repentant Achenar are killed. D'ni is not fully restored until the creatures the D'ni enslaved, known as the Bahro, are freed.
