A binding book functions in exactly the same manner as an iron flask, with the action of opening the book equivalent to stoppering/unstoppering the flask. The types of creatures in a newly discovered book are different from those found in an iron flask.
This heavy tome’s blood-red, rune-laden leather cover has no title along the spine. Instead, the front cover bears a warning in Abyssal: “Some secrets should forever remain unknown.” Judging from the edges of the pages visible on at the closed book’s side, the paper is made of the same high-quality material a wizard would use for his spellbook.
