The Libram has obsidian and darksteel bindings along with a broken belt clip. It is black leather cover with the cult insignia on the front which looks like the mirrored shield but with an eclipsed sun. Pages are written in a combination of ink and blood. Pages may or may not be of mammalian organic material.
It contains hymns, ballads (pre and post time travel and cult), sorcery, a treatise or two on her paradigm, and a history of her deeds, including her hidden grottos. It also includes entries from the Eclipsed Malediction of the Dark Father himself. And it is a journal as well.
