I really like the idea of Lucifer being a subordinate of Yahweh and that the two Isu ended up being at odds with each other, one trying to shepherd humanity through ruthless oppression and the other believing they should be exterminated or completely enslaved.
As Sol Pacificus had already pointed out, the link between Lucifer and Satan is mostly a modern invention. In original Hebrew, the term "satan" is a noun from a verb meaning primarily "to obstruct, oppose". Ha-Satan is traditionally translated as "the accuser" or "the adversary". The definite article ha- (English: "the") is used to show that this is a title bestowed on a being, versus the name of a being. Thus, this being would be referred to as "the satan". There are in fact several individuals within the Old Testament who were given this title, some of them just being regular ordinary humans.
Another modern mainstream perception is that the Serpent in the Garden was also supposed to be Satan. There is nothing in the actual text to suggest that this creature was supposed to be anything other than a talking snake.
The idea comes from that one time that Jesus referred to Satan as "that old serpent", but he also referred to the Pharisees at one point as a "den of vipers", which is obviously not meant to be taken literally.
The serpent was cursed to forever crawl on its belly and eat dust until the end of its days, indicating that this was supposed to be a mortal creature who would one day die (not to mention the fact that Satan was depicted as walking in the Book of Job, which is supposed to take place later).
During the Renaissance, most people believed that the Serpent was Lilith who, in stereotypical evil ex-girlfriend fashion, tricked Adam and Eve as petty revenge for Adam's rejection of her. Most Renaissance artworks, as such, depict the serpent as a half-lizard/half-woman.
It would actually be quite interesting if Lilith was incorporated into the AC-verse as perhaps a human who collaborated with the Isu during the Human-Isu War.
