Lucifer

Lucifer, also known as Satan or The Devil, is a man of vaguely Semitic appearance hailing from Hell. He is the main antagonist of the Neon Dragon story.

Lucifer is a powerful Thaumaturge, being skilled in Blood, Shadow and Deception Thaumaturgy, and having some skill in Noise Thaumaturgy. He refuses to practice Theurgy.

Lucifer used to be a literal Angel before rebelling against God and being cast down to Earth, eventually retreating to Hell. Naturally, Lucifer is despised by both the Christian and Muslim world, and his greedy and psychopathic nature turns most other people against him as well.

When the Neon Dragon was discovered, Lucifer returned to Earth with the aim of slaying it himself so that he might be powerful enough to challenge God once again. Through Deception Thaumaturgy and his characteristic compulsive lying, he managed to build a party to follow him, most of which died on the adventure.
