Satan (formerly Lucifer) is the devil, and the great adversary of God, and his son Christ.
Background[]
He is the ruler of Hell. It is believed that Pope Sylvester had made a pact with Satan. Sylvester may have been the basis for the story of the magician named Faust--a man who made his own pact with the devil.[1]
Evil spells are considered devilry having originated from the deviltry.[2]
Satan is spoken of in the Bible.
Behind the scenes[]
Abdul Alhazred alludes to the devil, when he calls Alexander a devil, and tells Shamir to '"Kill the devil quick..."'
Perhaps he is associated with the Lord of Darkness mentioned by the unicorn in KQ8, if that title doesn't apply to other characters in the game such as Azriel or Lucreto.
