From the campaign:
Our goal is to tighten things up just a little and make one massive reference book for you to use at your table. To do that, we need to round up all the monsters from the extensive C&C library and bring them into one book. This is what we have in mind: Monsters & Treasure, Classic Monsters, Mystical Companions, published adventures like Shadows of a Halfling Hall (looking at you, Bag-o-Bones!), Amazing Adventures Manual of Monsters, Codex Celtarum, Codex Germania, Codex Nordica, Codex Classicum, Codex Slavorum, Haunted Highlands and all the other manifold publications where monsters creep and crawl, fly and charge from the pages and put them into one monstrous Full Color book.
The campaign is already over its funding goal. So it's onward through stretch goals for the next 15 days.
