Erin and Joh-on both go to the Capital to shop for supplies. There, Erin meets a man named Ia-lu, a Seh-zan, playing a lullaby "Birds of Dawn" on the harp. Later, Erin meets Ia-lu again, who was about to kill Nuk and Mok, the two former egg thieves she met in Ake. While hearing a woman nearby singing "Birds of Dawn," she manages to convince Ia-lu from killing them. Ia-lu gives Erin his harp and the two former egg thieves say that they will follow Erin to repay her for her kindness.
