So-called Feral Humans are humans who do not live in the technological-industrial civilization controlled by the Great Corporations. The vast majority of these humans are not shareholders and have to survive by some form of labor.

Feral humans are largely relatively nomadic, though some have fixed settlements in regions of unusual abundance. They compete with each other, with feral mons, and with farming and resource harvesting workers sent out from urban civilization. Lifestyles including hunting and gathering, subsistence farming, and nomadic herding. They may or may not live or work alongside mons. In general, relationships between feral humans and feral mons are more consensual than those mediated by uMon.

The great corporations subtly encourage the extinction of feral humans, because of the potential threat they represent to the social order, but do not make unprovoked attacks against them, as is sometimes done when mon civilizations start to become excessively well-developed. In some cases feral human slums abutting fortified town are even tolerated. This used to be more common, but investments in recycling have reduced the amount of waste available for interception by them, and hence the incentive to live near shareholding civilization.
