There are no women in the men's wing and no men in the women's wing (disguises notwithstanding). However, inmates are not strictly divided by species; wings are assigned based on potential trouble arising from specific traits or compatibility. Naturally, the severity of the crime is also a factor. Those with heavy sentences are moved to different rooms and wings. Sentences exceeding 100 years are common, as they are adjusted to the lifespan of the species. Various roles exist; even among prisoners, there are smugglers, merchants, and those with deep connections.
