Demons - L

Lesser Demons = Most Infernals encountered on Earth are Lesser Demons who can appear human. See Lesser Demons. 
Lillith's Get = See Lillith's Get.
Lords of the Pit = These Infernalists, most of whom are Fallen Adepts, believe that when the End Times come and Hell rules over Earth, they will be granted power and prestige by Lucifer. Most of them honestly believe they will rule over a domain in Hell as a sort of duke or baron. LotP are avid practitioners of all sorts of Black Magick and they are devoted Luciferians. For more info see Lords of the Pit. 
Luciferians = In short, Luciferianism (external link) is a religion that sees Lucifer, the first among fallen angels, not as a villain but as a hero. To them, Lucifer defied God out of a sense of righteousness and his fall from grace was thus an unjust punishment from a tyrannical God. Luciferianism is most common among the Damned (big surprise there) but it can also be found within other Supernaturals, most notably the Order of Fallen.
