Chiya was an old man with a very wrinkled face. He had white thick hair, a thick white beard, tan skin, and a missing tooth. Because of the Tree Fever, part of the left side of his face had green blotches on it.
As a Shandia Pantri priest, Chiya was most likely very wise. When he was dying, he believed that the Tree Fever was a curse by the gods and wanted to sacrifice someone to plead forgiveness.
About 400 years ago, the pantri of the time fell ill with Tree Fever. Before his death, he appeared to be in delirium and told his tribe to sacrifice Mousse, to make the gods forgive them and cure them of their curse.
