Uruks are a specialized breed of Orc, they are bigger, stronger, more resilient, and most importantly, more intelligent. They were used as gladiatorial fighters in the fight pits for the amusement of the people under the banner of the Romuli Empire. This practice started with Romuli soldiers capturing Orcs and Uruks, along with the other warrior type cultures that followed them, and saw they're immense appetite for war and violence as perfect fighters in the arena.
But rather than go and capture the Orcs on the battlefield, the Romuli started a breeding program, making bigger and stronger breeds of Orc and Uruk. But the Romuli still weren't satisfied, and soon discovered that the Uruk breeds had the capability to mate with human women. Using slave girls for this process, this new breed of Uruk was more intelligent thanks to its human mother, but lost nothing in terms of it's strength, resilience, and ferocity.
This is the story of how the Uruks, along with the Goblins, Orcs, Ly-Kan, the Reptarri, and the Greco-Humans broke off from the Romuli Empire to create the Uruk Dominion.
