The Muza were a sentient species native to the planet Muzara, in the Expansion Region. The Muza were large, strong beings with massive overbites and scoop-like teeth. Their forearms were highly muscular. They descended from ruminants and established themselves as the dominant lifeform on their homeworld through the extermination of all large predators there. The species' religious beliefs revered certain areas of their world as sacred and shunned others as unholy. The ruins of Kabus-Dabeh, for instance, were regarded as the former home of an ancient and evil people. As nomadic clansmen, the Muza had no sense of individual property or territory.
