A primitive and devout civilisation was carved into the dust-filled canyons of Mars. These aging and severely eroded habitations miraculously remain intact, regardless of how much Grineer machinery has been fastened to it. Rusty metal and oil-soaked sand mark the territory of its new proprietors.
On the border of chartered space, an enclave of small, strange, seemingly intelligent creatures was discovered by Tenno explorers. They are mechanical entities, almost organic in appearance, with a precarious resemblance to the fearsome Sentients that had decimated human civilisation. However, these creatures showed no signs of aggression, and they immediately began carrying out helpful tasks in a peculiar alliance with the Tenno.
The Grineer have reclaimed the abandoned dwellings of an ancient society which sprung up around a massive Orokin terraforming device. Content to make use of existing structures, Mars’ current occupants have established a base of military operations in one of the few regions that has a habitable climate moderated by Orokin technology.
