This colony was set down to be a primary industrial node for the planet. Able to mine, construct, and forge a large supply of what was necessary for the capitol in order to facilitate the expansion of itself and other colonies so the resources could be in turn extracted and delivered to Earth. This left it at somewhat a disadvantage with in the way of a food supply, but that was assumed to be taken care of either on earth's end or from other colonies in trade.
When the planet started mutating people and the colony stopped getting fresh shipments of food and colonists, The people of MAchinia turned inwards. They started crafting machines to and constructs to make up for the lack of people, and started strictly controlling and managing resources and food to maintain their longevity. Thus Machinia it's name, for it's highly regulated society and constructs.
