From the campaign:
Creatures of Vathis: Volume One will contain over one hundred creatures that can be found in the world of Vathis. Though developed for our world, these creatures are versatile, and they can be used in any setting! Within this bestiary you will find four new creature types: vastborn, living eldria, vathrin kami, and the forsaken. You'll also find a variety of beasts, monsters, mounts, and companions, all itching to be a part of your game. For this book we have been lucky enough to work with some amazing artists who have truly brought our creatures to life. While we support both Dungeons and Dragons 5th Edition and The Pathfinder Roleplaying Game, our initial goal is for Dungeons and Dragons 5th Edition only. The rules for Pathfinder will be our first Stretch Goal. The book will contain full lore descriptions and beautiful art for every creature and type.
The campaign is already over its funding goal (as you can tell from the picture), and so it's on to stretch goals for the next 24 days, which includes rules for using the monsters in Pathfinder.
