Working on the backstory for the demons in my urban fantasy. Looking for thoughts. Too Christiany? Demons were once angels, the beloved servants of God. Yes, the God of Abraham, Isaac, and Jacob. He Who Is Called I Am. That one. Other gods exist in the story. Why and how you ask? Because I said so. Actually the story most go with is that pantheons of the Old Gods (Norse, Greek, Aztec, etc) began as humans so venerated in life they lived on after death. That or they were just members of the Fae (fairies) screwing with people. Basically pagan gods are super-ghosts that fed off worship/remembrance. It doesn't work that way for God. "He" requires nothing from mortals. Carrying on... Angels were the only beings in existence allowed to view god in all his glory, as doing so would completely destroy any other being. God is apparently comprised of concetrated awesomeness. Angels themselves can APPEAR as humans with wings, but this is for the good of humans. Their true forms are impossible for the brain of mortals to deal with. Then God created man and commanded that all in Heaven bow in reverence of this new creature. Those that would become demons refused. Muslims credit Iblis with this choice, and many Christians speak of Lucifer as leading a rebellion, a "war in Heaven", over this. As many a demon will point out, that is bull****. No demon has ever claimed to be either of these entities, and some claim they never existed. There is an angel called "the Satan" (which means Adversary), but he is just charged with testing men's faith. That is his freaking job. Demons claim there was no singular leader of the so-called rebellion. The various "Fallen Ones" simply refused, for various reasons ranging from jealousy to pride to whatever, to do as God commanded. Enraged, God cast them down from Heaven into the Pit. While man was given free will, the angels were meant to serve God's will. It was not their place to refuse the will of God. Which of course begs the question of how the angels could refuse God in the first place, but let's not think about that too hard... The Pit is a realm with no substance, supposedly a pocket reality devoid of any connection to God. Hell is not fire and brimstone, it is nothingness. A state of existence with no sensation and no real concept of time (as nothing ever changes). Within the Pit one is essentially a being of pure thought. There the demons would have (from their perspective) eternity to think over their refusal to follow God's will. More than a few probably went insane in there, only to come full circle back to sanity after they bored with craziness. Then someone rigged a jail break. The details are a little hazy on this point. Some claim ancient witches somehow breached the Pit and let demons into our world. Which becomes a chicken and the egg argument, as many claim witches got their "natural" gifts from demons. Other believe the demons themselves breached containment. Yet others claim perhaps God, having decided He might have overreacted a tad, let them out. This last one would paint God as something of a dick, though, as he would be letting a group that despise humanity loose on humanity. Then again read your Old Testament. God is not all love and hugs, and he works in mysterious ways. Regardless, demons crossed over into the mortal world. And given their origins most are not exactly fond of humans. Most demons can only infect the human mind, becoming the devil on the shoulder or in some cases driving people violently insane. It is said that demons cannot actually be destroyed, only be driven from a host via exorcism or said host's demise. More powerful demons can alter a host, even created "lesser demons" out of humans in a mockery of God's power of creation. This led to the first vampires. Vampires kill victims in this work (they feed on life to sustain their unnatural existence, not blood itself), so they are kind of the demons payback on mankind.
