This section provides the Clavicula (keys). The language is a hybrid of Latin, corrupted Hebrew, and Enochian approximations. A typical invocation line reads:

"Lucifer Princeps" is a book written by Peter Webber, a well-known occultist and writer, and Stephen E. Flowers, a renowned expert in the field of occultism and magic. The book explores the concept of Lucifer as a symbol of enlightenment, individualism, and spiritual growth.

Modern Luciferianism (e.g., the work of Michael W. Ford) views Lucifer as a Promethean figure of enlightenment. Lucifer Princeps views him as a literal, feudal king of Hell who demands submission and offerings (blood, breath, or written oaths). They are philosophically opposed.

Grey writes from a perspective that challenges the orthodox Christian "Satanization" of pre-Christian deities. He seeks to "rescue" the figure of Lucifer from the baggage of medieval demonology.
