"Centuries ago, Earth began to colonize Mars. During their terraforming was a great revolution of cruelty and disease brought upon by the mutation of human bacteria, but that was abruptly ended by the Scorch. The Scorch is the name of the massive solar flare that cut off all communication between Mars and Earth. Now, nearly a millennia later, there are survivors. You have the Iconoclast - a group of high-class society members who sought out to be an existentialist colony but eventually corrupted themselves through hypocrisy. They control most of Olympus Island by funding mercenaries that enforce their rule. Next is the Abbatial, a church of sorts that worships Infected abominations as pieces of a divided God. The Tribals were ex-aviators who were exiled to the ground and swore to hunt down all the Infected that plagued Mars. And finally there are the Underfolk, colonies set up in old mining settlements underground. Most of them don't even know - or want to believe - that there is a world above the surface."
