The Litany originated in the Liber Defuctorum created by the Sabbat to honor those who had fallen in the struggle to establish the sect in the Montréal region around the 1660s. Under the guidance of Sœur Marianne, other stories of different dioceses were added and several Noddists contributed by providing genealogical notes on the fallen.
When Marianne left Montréal for a life of isolated contemplation, the Litany was passed to her Noddist aides, who formed the Librarians coven. Under the Librarian's care, the Litany was standardized and the Skintomes became their medium. The original paper records are maintained, although several were lost in fires over the centuries.
The Librarians moved the Litany to a new venue, a spectacular library called Alexandrium, which was linked to the newly constructed Temple of Eternal Whispers. The modern Litany is written in tomes of flesh inscribed with refined vitae enabled by a combination of Thaumaturgy and Vicissitude. It is divided into three tomes:
- The Book of the Fallen details the sacrifices of Sabbat members, their Final Deaths and – if available – a short biography.
- The Book of Trees details the lineage of each Sabbat member accounted for in the Litany, with ancestral charts that ostensibly date back to Caine and the Second Generation.
- The Book of Champions details the most heroic deeds of Sabbat members, be they individuals or packs.
The Opening of the Litany is an annual tradition of the Montreal Sabbat and many luminaries of the sect come to witness the festivities (that include a presentation of the Choir of Caine), and study the Litany under supervision.
