The name Lucifuge comes from two Latin words; lux (light; genitive lucis), and fugio (to flee),which means "[he who] flees the light". The proper pronunciation of "Rofocal", one should note, is an anagram for Focalor, which is the name of another important demon who is possibly in his servitude.
In some modern left-hand path belief systems, the demon Lucifuge is said to be the ruler of the qliphoth Satariel. This belief originally comes from a claimed translation of an ancient Hebrew manuscript made by Eliphas Levi and has since then gained acceptance.
Modern-day occult orders such as Dragon Rouge, the Order of Phosphorus and the Temple of the Black Light incorporate the idea of Lucifuge as one of the eleven rulers (there are ten qliphoths, and the last one, Thaumiel, is split in two, thus making eleven).
