After a number of world wars in the way of nuclear detonations across the globe, humanity faces extinction.
As the environment recuperates, centuries of mankind's industrial footprint is rapidly taken overtaken by nature and a flurry of snow that never seems to stop.
People separate into settlements, and there are a lucky few who establish trade routes. Others in more remote locations are left to fend for themselves, and people have always managed that in one way or another. In these dark time, they manage it in truly barbaric ways.
Grotesqueries
Immediately after nuclear fallout, people fell back on food reserves--canned goods, preserves, water hidden away in bunkers. Those were finite, and soon people were forced to eat irradiated food or die to starvation.
Those unlucky few who survived lived long enough after the war would breed, and their children would breed, and their children after that. In time, most people became grotesqueries; beings afflicted with tumors in place of limbs. It is not yet known how or why these tumors, seemingly sentient apart from their host, sometimes full of bones or eyes, developed en masse or how they helped humanity adapt, and no equipment exists to test these growths.
Typing
Grotesqueries are separated by type and severity, whether the growths are benign or malignant to the host, or if by some chance the growth serves a visible purpose in aiding the host.
An adaptive grotesquerie is a growth that grew to take the place of a missing limb.
Mild to Advanced grotesquieries are categorized by four or more growths. The rapid appearance of a growth immediately qualifies a person as an advanced grotesquerie.
Life after armageddon
As food is scarce and communication between settlements is tenuous at best, scavengers have become an integral part of society.
A scavenger's purpose lies mainly in finding food for remote villages. They live nomadic lives and tend to be solitary.
The soil is either unfit for growing plants or covered under inches of snow at any one time, making farming and animal husbandry impossible in the villages where trade routes haven't been established. It is a scavenger's job to travel to these remote areas and find the willing weak, elderly, or otherwise compromised and execute them as mercifully as possible so that the people might eat. Usually, if there is not enough to go around, the meat goes to the deceased's family.
Has this diet contributed to the development of grotesqueries?
