'Alpha and Omega' is a term that originates from the Bible, specifically the Book of Revelation, where God describes Himself as 'the Alpha and the Omega', symbolizing that He is the beginning and the end. In pop culture and sci-fi genre, the term is often used to portray something that is all-encompassing, fundamental, or key to an overarching plot or purpose. The term also has found its place in a series of urban fantasy novels by Patricia Briggs. The 'Alpha & Omega' series starts with a novella of the same name and follows the tale of Charles Cornick, the enforcer for the leader of the North American werewolves, and his mate, Anna Latham.
