Chaika was the daughter of Bako. Born in Delphi, her mother and elder brother were killed when that city was crushed by the combined ape armies. Unlike her brother, Chaika was born mute - part of a new generation of humans unable to talk. Bako escaped with Chaika to the ape/human city of Mak, where she grew up. In common with the other mutes of Mak, Chaika became a radical opponent of the ape leadership and came under the influence of Brother Kale's cult. With weapons supplied by Kale, Chaika assassinated the Lawgiver and prompted a war between apes and humans in which she was killed.
