Demor, or Denior, is a demon mentioned in the Munich Manual who can cause hallucinations and delusions and make massive castles appear. When summoning him, conjurers venture to a covert location where they offer him milk and honey.
Seals and characters for summoning the greater demons Lucifer, Beelzebub, and Astaroth. In order of effectiveness, the symbols must be drawn in either: the sorcerer’s blood, the blood of a sea turtle, or engraved on emerald or ruby. From Grimorium Verum (16th Century) and The Grand Grimore (18th Century). Source: “The book of black magic and of pacts”, A.E. Waite, Embassy of the Free Mind
