TzHaar are a race of golem-like creatures that inhabit the TzHaar City, a lava-filled region beneath Karamja Volcano. The word "TzHaar" means "holy (sacred) fire". The TzHaar society is unlike any other and only vaguely resembles any that exist on the surface.

Despite their fearsome and powerful appearance, the TzHaar are a peaceful race and have existed beneath the surface of Karamja for thousands of years. Even today, the finer aspects of their society remain a point of great mystery.
