Chirogs are vaguely reptilian abhumans with thick armor plates covering much of their bodies. They live to hunt and kill, but despite their savage nature, they are craftier and more intelligent than most abhumans. They understand the numenera—and despise it. Even more than killing humans, they enjoy destroying the relics of the past. Perhaps it is racial resentment for wrongs done to them long ago, but no one really knows.
Chirogs live in small packs with a clear leader who is usually a female. In fact, she is likely the mother of many members of the pack. The creatures have a tangled, incestuous relationship, and mature females eventually leave to form a new pack, sometimes taking a brother or two with them.
