After Riko is stillborn, Ozen curses Torka for getting Lyza pregnant, dying, and leaving Lyza in such a miserable state.

Lyza becomes a White Whistle, vows to hunt down whoever injured Ozen, and finally tells Ozen about her marriage with Torka. In flashbacks, the rest of Ozen's history with Lyza is revealed. Ozen privately admits she would prefer not to have sent the kids away until she had reminisced enough. Ozen also gives Blaze Reap, a former Artifact of Lyza's, to Riko and reveals secrets only passed down via word of mouth between White Whistle Delvers. Marulk and the other Subterranean Bandits say farewell to Riko and Reg, who are now ready to enter the 3 rd layer. Ozen passes many secrets on to them known only to White Whistle Delvers. Ozen warns them not to linger once they reach the 5 th layer and beyond, in order to avoid meeting the other White Whistle Delvers: Wakuna, Srajo, and in particular Bondrewd. Using this logic, Ozen suggests that even though ten years have passed, it is possible that Lyza is fine. Ozen tells Riko and Reg that within the Abyss, a person's sense of time is broken: time seems to pass slower in the depths, but faster on the surface. After 10 days, Riko and Reg return to the camp, where Marulk congratulates them, admitting that the training doesn't usually last so long, and that he failed in his own attempt. However, they are improving at what they are capable of and cover for each other. Meanwhile, Reg has a strong body, but is jumpy and slow to make choices. On the third day of the training, one of Ozen's Subterranean Bandits, Zapo, reports to her that Riko has good instincts, but her body can't keep up.
