While this text continues what Gilles' first two books provided, Rites turns away from a strictly Luciferal focus to more of a Qliphotic presence and collection of rites, talismans, and other similar concepts. If Explicit Name of Lucifer was the Luciferal Lesser Key, this is the Greater Key. This is far from a beginner's text, and would require the cipher from Explicit Name in order to get the full text. But that aside, this is another fantastic addition to Laval's books.
