Aside from Christianity, which someone could talk about concerning demons for decades, there are other religions that discuss them. Through the work of believers and extremists through the years, demons have been catalogued and vilified as malevolent otherworldly entities. But what do these other religions say about demons? Chances are, religion dating back to the first humans contained some form of demons or spirits. The Zoroastrian belief system, commonly considered the first monotheistic religion and practiced in what is today Iran and the Middle East, taught that demons numbered 3,333, each with specific responsibilities. These were dark responsibilities, including war, starvation and sickness.
Judaism, while never subscribing to any official statement or description of demons, does discuss demons. The Talmud describes over 7 million demons divided into some 72 companies. Other texts and stories describe the genesis of demons including vampires, demon-locusts, impure spirits, and humans turning into demons through their wicked ways. Some scholars think the Jewish concept of demons is based on ancient Zoroastrian tradition. In Islam, demons are free from the inherent evil ascribed to them by many other religions. Iblis, the being who refused to kneel before God and received damnation, was not an angel or demon. He was a jinn, a creature that could do good or evil by choice, just like humans. But because of his action in defiance of God, he fell. Buddhism touches briefly on demons as those who thwart the search for enlightenment.
Next is sort of a Demons 101, a hit on the highlights of the demonic legions. There are many, many more out there, this is just the basics. The information about each is taken either from the Supernatural Book, if I couldn't find anything decent online, or Deliriums Realm, which was taken directly from Goetia, the Lesser Key of Solomon. If I had to quote it and it sounded funny, I changed words like 'knoweth' to 'knows' and 'appeareth' to 'appears', etcetera.
