Sins of the Past
Genetic Aliens, or “G.A.s” as they are colloquially known, are a subgroup of the human race that number in the millions. They represent those people who, in the years after the Eruption, were either born with or developed significant alterations to their DNA that made them, essentially, no longer human. Unlike traditional mutations, however, G.A.s do not seem to mutate randomly, as in there are a finite amount of re-combinations that have been cataloged (well over 50 at this point). Even more curiously these mutations almost always breed true, in that a child born of a female G.A. will always exhibit the same mutation as the mother. In the 300 plus years following the Eruption, this genetic heredity has fundamentally changed the social structure of the planet as dozens of different “species” began to flock together into communities of their own while often being ostracized by what came to be known as “true humans,” or those members of the species that show no signs of genetic mutation.
No matter the culture, G.A.s are almost always looked down as a lesser class, and as such they rarely possess the benefit of advanced medicine, technology, or anything other than the absolute basics. In large cities such as Egypt they fill the slums, each district belonging to a specific species or two, and such districts are always territorial in nature. In more rural locales a singular village or settlement usually consists primarily of a single species who are distrustful of outsiders, especially those of a different species as their own.
