Demon

Demons are a race of sentient, subterranean beings. Most are humanoid, but typically taller and more muscular, with black eyes and wildly varying colors and appearances. Seldom sighted above ground, some are nearly indistinguishable from a Human in appearance, while others have been seen with horns, leathery skin, bat-like wings, or even fur.

Their wide variety of forms make them difficult to categorize, but they all share a few traits. They typically have some varying vulnerability to sunlight and an affinity for darkness, as well as an ability to subsist on little food or water. Most exhibit a strong tendency toward antisocial behavior, selfishness, and hostility, and a story involving one or more Demons will usually involve conflict. They are not immortal, but seem to age very slowly, and some have been known to live for many centuries.

There is no sense of government or civilization among Demons; it is very rare that they organize into any sort of groups or societies. On the rare occasions that they gather, it is typically as an assault to gain land or material wealth, and even then, a Demon army typically disbands into chaos soon after the fact.

It is unknown if some or all them are carnivorous, as there exist (possibly dubious) accounts of Demons hunting Humans and eating them. Most Demons stay underground, coming up only very occasionally, and always at night. Throughout history, Demon sightings have typically been very rare, most often during times of war or crisis, when they are better able to take advantage of surface dwellers in some form or another.
