Manual of Nosferatu

Nosferatu: How it Starts, How it Propagates Through Populations, is and ancient tome written in Old Landellian, dating to before the end of the Golden Age. It details how the original Nosferatu type of vampire came into being and how the curse can spread through unsuspecting populations. It contains information on the creature's strengths, weaknesses, methods of propagation, etc. There is even enough speculative information to lead one to suspect that it could be recreated artificially. In the margins, one reader (Evelyn Katarsis, deceased) expounded upon said speculations. The book is paired with her own personal journal (also written in Old Landellian), where she develops the idea and runs experiments using the resources of her unsuspecting husband until she is successful in turning herself into a Nosferatu, at which point the formula is then laid out clearly. Anyone that knows it and can gather the components could, theoretically, recreate it. The books, paired together, are considered to be highly dangerous and collectively known as the Manual of Nosferatu. The manual is currently in the hands of the Church of Helerion for research purposes.
