A mysterious tome discovered in the private possessions of Cedrick Frohwein on Silence. Though Navigator Maturinus detected a strong warp taint on the book, it is currently in the possession of Lord-Captain Jequin Hos.

Though Jequin Hos thought this book should be turned over to the Inquisition in a show of faith and proof of their piety, a unified front from Astropath Eckhart, Navigator Maturinus and Explorator Felicis changed his mind, and the book was destroyed.
