Who is Chnay from The Clay Marble: And Related Readings and what is their importance?

Chnay is a teenaged orphan, first encountered by Dara and her family in the Nung Chan refugee camp. Something of a bully, he maliciously destroys several of Jantu's delicate, beautiful toys for no other apparent reason than he simply can. Later in the narrative, he helps Dara survive being lost and alone, the two of them eventually forming a somewhat grudging friendship. As the novel concludes, a more mature Chnay apologizes for the mistakes of his past, and reveals, in a secondary manifestation of the novel's thematic consideration of the nature of family, that he has found a sort of family of his own with a group of other orphans at a military base.
