Red Hand's Book

"'Hey Warren. Writing this to say if I die today, my stuff's hidden under your doorstep...Take the book and put it where no one can find it.' - The Red Right Hand, shortly before their death at the 4 hands of the Mechanic"

Summary
The Book is a magic book that has multiple unusual properties. It has been confirmed to be indestructible, and can only be read for so long each day before it becomes completely unreadable, headache-inducing gibberish. It contains a vast wealth of information on magical rituals and the nature of various entities, but only small chunks of said information can be learned from it each day, and whatever information is in it is fairly random.

History
It is unknown where the Book came from, or how exactly it got to Red Hand, other than it was given to them as a sort of self-help book to aid them in their recovery. It is also unknown what Red Hand did with the Book before joining the Congregation. Red Hand has used it to summon Suefrean in order to deal with the potential Code M presented by BILLY DEMONAYS as well as to gain information on the nature of the Face and AETHER.

Before their death, they gave the Book to Warren. Star saw Red Hand bury it, and thusly dug it back up. As it reeked of Red Hand, the Mechanic attacked Star and Warren, but was killed. The book later disappeared into thin air.

Its current whereabouts are unknown at this time.
