Unwinds are children from the ages of thirteen to seventeen (13-17) set to be unwound. As of UnWholly, the age limit was lowered from 18 to 17, resulting in a shortage of unwinds and spare body parts. Parts pirates have since run amok and have began selling unwound body parts at the black market.
Unwinds who manage to run away are considered, and called, AWOL.
Unwinds are considered unequal to their tithe counterparts, as their parents had chosen to unwind them while the tithes believe in their own unwinding. As a result, unwinds hate tithes, and vice versa.
