Eduin discovers that Saravio has an odd "laran" talent – the ability to calm the mind of another by singing. This talent breaks one of the most important vows a tower worker takes – not to force his/her mind on another unwillingly. However, the singing quiets Eduin's internal demons, and he comes to believe he can exploit Saravio's gift to further his vengeance on the Hasturs. He also discovers that Saravio is obsessively devoted to Naotalba, the mythical wife of the god, Zandru.
