'Millions of years ago, when giant reptiles were walking on the Earth, there was a nearby arid planet inhabited by a humanoid nomad tribe called Hazai.

Although they were biologically similar to humans, they differed in their basic appearance, body proportions and outer limbs muscles making them faster runners and climbers when hunting.

The Hazai shared the land with the Kiroi, probably the largest animals of that planet. Although their diet didn't include Hazai flesh, the Kiroi would attack if they felt intimidated. Those with the darkest fur and brightest colors tended to be more aggressive and territorial.'
