An Arabic demon or spirit, created by Allah from smokeless fire. Jinn were created before humans and can be resentful at what they see as the usurpation of the world by humans. They are generally invisible, but they can manifest themselves in a variety of forms and can always see things that are normally visible. Jinns occupy a place in Islam unlike demons in Christianity because the Koran is preached to them as well as to humans. Still, they are often feared. A kind of jinn known as a marid had control over water, with all of the power and fickleness that that might imply.
