The Book Of Lucifer and His Writer

I've been reading The Nine Gates and there is already something about the man who made a pact with The Devil, Artiside Torshia who wrote the book in 1666 and a year later was burned at the stake and all of his works destroyed. Looks like Lucifer didn't help the man who made a pact with him and he wound up being executed for this. Moses on the other hand wrote 5 books in collaboration with God and he wound up being God's law giver and was buried by God himself.
