Praetorians (Battle for Earth: Prime)

The Praetorians are a nation that has a strange background. The race began in the test tubes of another race, as this race could not leave the atmosphere, but was incredibly advanced. They wanted to colonize space, and created the Praetorians as slaves to exploit the resources of space.

The Uprising
In the year 0 of the Praetorian Calendar, the Praetorians (then just called 'Slave race 1') on the Space mine of Praetoria rushed the turrets guarding them. The Evil Ones, as the Praetorians call them, could not reach this Planet, and then had to watch as their empire crumbled around them, powerless to do anything. By the Year 100, the Praetorians owned the entire of the Evil Ones empire. When they owned the entire empire, the Praetorians changed the atmosphere of the Evil Ones homeworld by 1 percent between the two gases that make it up. The Evil Ones died within days, as they are hyper-sensitive to changes of the atmosphere. In the year 101, the Praetorians landed on the Planet. They discovered a laboritory on the surface, that had horrifically mutilated Praetorians on it. As they explored the Laboritory, they discovered a vial of fluid.

Genetic Modificator
The vial of fluid was a godsent to the Praetorians. The Evil Ones had been creating it to lower the threat of the Praetorians. Praetorian Scientists that studied the fluid discovered why the Evil Ones want them to take it. It removes the urge to attack other species that the Evil Ones implanted in them. The Praetorian Scientists discovered that it also increased the intelligence and sophistication of the Praetorians. After much deliberation, the Praetorian Battle leaders agreed to spread it throughout the Race. They then discovered that it had one other, unforeseen side effect, a strong urge to protect weaker races.

Empire
The Praetorian Empire is no larger than it was when they inherited it from the Evil Ones, but this is not due to failures in wars, as they simply haven't tried to expand. They have been attacked by another Species once, and they fought them off, but the other race simply threw themselves into the war. The Praetorians lamented the fact that the other race destroyed itself in the War, but, ever pragmatic, took over the lands of the other race.
