- "And their flesh shall nourish yours, their blood shall flow within you, for as the beetle nourishes the lark so shall human nourish vampire."
- ―Excerpt from the Book of the Vampyr[src]
The Book of the Vampyr, alternatively known as the Original Testament and the Vampire Bible, is the sacred text of the Vampire religion. It is allegedly older than either testament of the "Holy Bible" used by humans and the original source material of the "Old Testament"/Hebrew Bible. It chronicles the creation of the universe, all life in it, the life and demise of Lilith, and the beginnings of the Authority. At no point does the text mention the possibility of Lilith returning or being resurrected, so Bill Compton's transformation after ingesting Lilith's blood came as a complete surprise even to those who knew the text well,("Who Are You, Really?"), although it was later discovered that the text held even more secrets than was previously thought.("The Sun")
Despite its prominence and central role in vampire society, its authenticity and accuracy are dismissed by many vampires. This includes even members of the Authority: Guardian Roman Zimojic didn't place much faith in the book that gave him his rank. Chancellor Dieter Braun claimed that the work's author, an acquaintance of his, was intoxicated while writing it.
