The Monster Rangers Notebook is a core tool, one used by every Ranger, as well as the Dark Librarians, who host halls of these notebooks. (All filled in by our trusty Field Agents.)
You can use this notebook for just about anything:
It measures 5x7, so it's quite a bit larger than our other handbooks. (Handbook 2 is shown for scale, and is NOT included.)
It has room on the cover to label it for your own Dark Library!
