The Nilito evolved on the same world as the Zoles, and in the Tribal Stage, when the Zoles became aggressive, they hunted down and killed the Nilito tribes, who were formerly allied with the Zoles tribes. The Nilito went into hiding, and were later taken as slaves by the Zoles in the Zoles' Civilization Stage.
When the Zoles Imperium was founded, with new lives, the Nilito were no longer treated as slaves, but preserved like any animal would be. Soon, it was discovered that the Nilito had signs of sapience, and when the Nilito were allowed to evolve, they became a major species of the Zoles Imperium.
Nilito have the equivalent strenght of 3 humans, making them strong, but still far weaker than a Zoles. While lacking the Zoles's strenght and endurance, they are far more dexterous. The Nilito usually fit the role of gunners in combat.
