The Liefeld Colony was one of the earliest independent colonies that cut ties to earth's central government. The colony was dedicated to pushing the limits of genetic modification in humans to create the ultimate in physical power.

Over the years, the colony has produced more and more extreme physical advancement among most of the population. Muscles piled atop muscles are the normal physique.

There have been downsides. In the quest for this physical advancement, safety, especially relating to mental and intellectual consequences has been ignored. The average Liefeldian lacks the inclination for education, and the systems in place for the youth primarily focus on athletics and martial skills.

The colony's main super computer known as I.M.A.G.E. was originally an aid to the scientists running the research, but has slowly turned into the only entity on the colony capable of sustaining genetic augmentation, as well as running all of the utility and infrastructure systems.

The material needs of the colony are demanding, and as such many Liefeldians are employed off-world as soldiers, bodyguards, and hired goons all in the service of sending money and resources back home to the colony. Liefeldians have reputations as tenacious and capable fighters, though not to be hired on missions where minimal collateral damage is required.

(I hope my reference with these guys is just obvious enough)
