Quote: Well the reason I went with is real is because its the promisedlLand and basically seemed as good as anywhere in middle when it comes to the garden. Its the fact that it is a suit from the 50s which is a time most Christians think of as more pure. The bible, whenever in depicts angels in any kind of military action, describes them as using sword, like a cherub with flaming sword gaurding eden. Satan in this story prefers human type weapons, especially if they were used by people standingbagianst religious tryanny. Also that flame could be made to move in any direction the angels want. And finally for the purposes of the story they are basically like us, to each other thus they can kill one another and what not. As for the mother bit, why not, the bible doesn't say how they all came to be
The exact location of the Garden of Eden is not known, and will never be known, because the bible states that its relative location has undergone various changes... whether it be the construction of the Tower of Babel (same location), or the great flood which eroded the landscape.
(still an imaginary place though )
So, really, anywhere in the Middle East is an OK place to start.
For the "omnidirectional" flame comment, I think You want "manipulable flames".
As for the friend of Lucifer, ~33% of the angels defected to Satan's army before God casted them out of heaven. So there are plenty of demons (fallen angels ) for Lucifer to interact with. For instance, his friend could have been Baal.
