Demons - F

False Prophets = Just as the name suggests, these Infernalists masquerade as genuine Christians (or as members of any legitimate Tribe). False Prophets delight in fooling those around them into believing they are kind and sincere, only to secretly undermine the group's practices and forge corruption within the ranks of the church. The Catholic Church recently suffered a major implosion when it was revealed that multiple sex abuse rings had been secretly at work within the ranks of their priesthood for years - the handiwork of the False Prophets.
Father of Lies = Biblical name for Satan or Lucifer, denotes Satan's aspect as the pervertor of God's plan and seducer of men's souls. Other Adepts often refer to this name of Satan to point out how Infernalists of any stripe can never be taken at their word. 
Favored of Lucifer = This is a name for the Order of Fallen which even Infernals have used. Lucifer, who was once one of God's foremast Angels, fell from grace the same as the Order of Fallen. It is said that Lucifer views these ex-Adepts as being particularly in his image. 
Flesh Rites = Flesh Rites are dark and vile rituals committed by Infernalists of the older traditions. These are often the collecting of leftovers from animal sacrifices which are used as unholy relics. Some Infernalists keep barrels, pits, trunks or entire cellars full of decayed or decaying body parts as some sort of appeasement to an eldritch being.
Forbidden Knowledge = Infernalists by their very nature deal in Forbidden Knowledge.
