The Anu species evolved a very long time ago. As a species, they are much older than humanity. For many millions of years already, they have lived in very technologically advanced societies, studying and learning, devoted to science and the intellect.
Their origins are reptilian. Throughout their evolution, they maintained claws on their hands with three fingers and a thumb, scales covering their bodies, and a tail. In the form they exist today, they are on average almost 3 meters tall, with males being larger than females. Their lifespan is much longer than that of humans: the Anu live nearly half a million of our years, and illness and accidents are rare.
