God created the Archangels; Michael, Lucifer, Raphael, and Gabriel.
Lucifer formed an especially strong bond with his brother Michael.
After the creation of mankind, Lucifer began to argue with his
brothers and with God over these new, imperfect beings. The arguments
became so heated and bitter that Gabriel chose to leave Heaven rather
than watch the fighting continue. According to Lucifer, God commanded
his Angels to venerate Man, but Lucifer refused, and was cast out of
Heaven. As an act of defiance, Lucifer twisted a human being’s soul
to create the first demon, Lilith. He was then confined against his
will in a Cage by God.
