The demons of "C&S" have clear origins in mythology, occultism, and prior works of fantasy fiction. They include (in ascending order of power): Gargoyles, Imps, Balrogs, Elementary of four elements, Jinn of the Ring, Jinn of the Lamp and Efreet, Knights of Hell, Fallen Angels, Powers, Principalities and Lords of Hell at the top of the demonic hierarchy. There is a spell of invocation to the demons of each circle of power; the most powerful demons require a black mass and a sacrifice for their invocation. The Magick User who wants to invoke a demon must first succeed in drawing a protective circle, then the devil appears and it can then be ordered to request a service or be bound for a period of time. The most powerful demons can not be bound but they know many secrets they can teach the Mage. Despite the interest and realism of the system, which makes a case demonic invocations no Mage can not afford to treat lightly, this part of the system has not been well integrated with the rules of magic and is confined to the end of the rules.
