A ruined tome, apparently a wizard’s spellbook, bound in brown leather, found in the basement of Briarstone Asylum with the rest of the gear the party picked up. Mangled, torn, reeking of urine, and covered in some sort of unknown fungus. Carried by Gull upon leaving the cells.
In Chapter 6, the party learned that the handwriting contained within didn’t match that of either Dora, Ray, or Grip.
In Chapter 14, Gull noticed that the fungus that had been covering the book was dying off and flaking away.
