Book of Dyzan
- English, author/translator unknown, reputedly of ancient origin. Quarto, bound in goatskin, woven papers, distinct smell of sulphur.
- Recovered by Jude Gregson from the secret room in the basement of the Penhew Foundation. As it is a handwritten document in some ancient English dialect, he couldn’t make any sense of it.
- Raskolnikov started studying it. After a visit to the library and the help of a librarian (who went psicotic) he was able to read part of the book
