Kozi was a Hilurin boy from Lysia. He was a childhood friend of Scarlet's who became a pedlar and disappeared on the Salt Road when he was 15. Scarlet mentions his disappearance and also that Kozi was a servant in a Morturii household before he became a pedlar.

In Rshan, Liall asks if Scarlet was close to Kozi, but Scarlet changes the subject.
