Anyone interested in demons will find a wealth of information on this site. Various articles discuss their origin, their history, their powers and limits, their activities, and their relationship to the Devil. There is also a large encyclopedia which lists the names, history, and attributes of dozens of individual demons.
In the encyclopedia section, I learned that a demon named Arazel, who is mentioned in the bible, has seven snake-heads, fourteen faces, and twelve wings. The book of Enoch says that it taught people how to make swords, shields, and other instruments of war.
The encyclopedia entry on a demon named Byleth says that it disguises itself as a magician riding a white horse, and that the sound of trumpets can be heard when it approaches. It is a high-ranking demon, but because it has a bad temper, it must be summoned with extreme care.
In a section on demonic possession, I read about the typical symptoms of possession, cases mentioned in the bible, some modern cases, and methods that exorcists use to treat the condition. Possible symptoms include violence, lust, greed, speaking unknown languages, amazing physical strength, and an unnatural power of persuasion. The discussion of modern cases suggests that many of the most evil criminals, such as serial killers and mass murderers, are possessed by demons.
