Lucifer

=The Morningstar=

History
In heaven, Lucifer was born to a wealthy family, and never wanted for anything. When he was growing up, he received a top of the line private education, and he excelled at his studies. He was always charismatic and generally well liked, and had no trouble with finding work or love. Finding the right one was a little more complicated, but eventually Lucifer fell in love with an angel named Asariel. She was kind and beautiful, and enjoyed Lucifer's company for who he was and not how much money he had.

Lucifer was the first fallen angel but not the first demon in hell.
