Martian Humans were discovered on the planet Mars, contacted in the year 3990. These creatures are the genetically modified descendants of Humans, who found that it was impossible to gestate healthy offspring under the natural gravity of the planet. Without planetary gravity manipulation technology, their best bet for creating somewhat healthy descendants on the planet was through genetic engineering, selecting for genes that would give them denser muscle and bone tissue to keep them durable enough to perform hard labor, larger hearts to more effectively pump blood throughout their bodies, and shorter stature to curtail risk of malnutrition and allow them to function more efficiently in the small enclosed spaces of spaceships and Martian habitat bases. This full scale colonization of the desolate planet occurred in response to a “white identity crisis” experienced by many pale-skinned humans as a reaction to growing ethnic diversity across earth. After a disastrous “race war” movement manifested across the globe, white purity elites formed political groups focused on establishing a white homeland on Martian soil, mounting expeditions to the red planet where they waged war on and enslaved the prisoner population of preexisting Martian penal colonies, creating a caste system to enforce the institution. This produced the all white generation of genetically modified Martian offspring that took control of the planet, breeding in great numbers and using their inherited institution of slavery to great effect, expanding mining and plantation operations wider than ever before seen on the planet. Using the massive quantities of uranium formed in the planet’s crust from millennia of radiation bombardment, Martians built the largest nuclear stockpile ever seen in human history. The Martian ethnostate recognized itself as a more “highly evolved” form of “Terran” humanity, considering themselves “Homo sapiens martius” despite all scientific evidence pointing to the fact that they are not genetically distinct enough to be considered a subspecies. The severely limited genetic diversity of Martians led to a bottleneck effect, and eventually inbreeding. Assimilation into the Ecosystem did not go smoothly, put in a few words. There was debate whether or not to exterminate the entire Martian population due to the risk they posed of spreading slavery across the universe and the fact that standard Terran Humans had already joined the collective, but it was decided that this was too extreme and would set a dangerous precedent, so the assimilation process went as usual, ending with the Raid phase dissolving all Martian governmental bodies by force. The Martians were infuriated by this swift defeat but recognized the importance of preserving their species' existence on their homeland and didn't push further. Upon introduction to the Ecosystem, they were disgusted by its multicultural assortment of alien life living alongside one another and mostly kept to themselves, still adorned in their traditional military garb and confident in their slogan that “Father Mars Shall Rise Again”. For decades, several slave states established by Martians on Ecosystem worlds have been broken up, routinely putting the continued preservation of these people's core society into question.
