A generally malevolent being with supernatural powers, typically evil spirits or fallen angels that taunt, tempt, and destroy. However, on occasion they may be neutral, show mercy, be wise, helpful, or beautiful.

Great care should be taken in dealing with any demon, no matter how insignificant it appears, as they often hide the extent of their powers. Also, a lesser demon may belong to a horde and while being targeted by one may be of no consequence, being targeted by the entire horde may be unpleasant. Furthermore, there is a demonic hierarchy which means that it's possible for even the least of demons to start a chain reaction that results in your offense being placed before an archdemon.

Exorcism is no longer recommended as a first line treatment for demonic possession. If possession is suspected the victim should be taken to a modern medical facility where they will receive clinical treatment, psychological therapy, and self help resources. Modern medical practitioners call demonic possession by different names (depression, psychosis, etc.) but the treatments are still effective. Only non-violent exorcism should be explored and only as a last resort.

Bottling is a method used to gain control of a demon's powers or as a first step towards vanquishing it. Demons that have taken possession of another being or object must be exorcised before they can be bottled. Unsuccessful bottling may result in property damage, bodily injury, or death.

Any information obtained from a demon should be verified by three sources before it's considered for any purpose. Reliable sources include your own personal observations and logical conclusions based on those observations, a knowledgeable sorcerer or priest, a sage, and/or a sacred text.

Demons exist as invisible forces or appear as inanimate objects, small reptiles or insects, domesticated or wild animals (see below), human beings, plants, little creatures, or huge monsters. They also masquerade as other supernatural creatures such as angels or aliens.
