Lucifer Morningstar
Samael, the Lightbringer, the most beautiful and powerful of God's Angels. He rebelled against his father and was cast from heaven, becoming the ruler of Hell for billions of years before finally deciding to abandon his prison and open a nightclub in LA...
Where is he from?
Lucifer as he appears in GND is based on the very cool 2016 TV series Lucifer, which in turn is based on the DC/Vertigo comic character. Of course, the concept of the Devil is as old as anything... but Lucifer isn't JUST the Devil. There are a few fun stories that dip their toes into creating more complex versions of the Devil, and we can look at a few of them here:
