Cloister Publications (that's me) presents RPG Creatures - Bestiary 1!

Currently available in print from LULU.com (Edit: unavailable in print until further notice).
and as PDF eBook from Drive ThruRPG and the Paizo Store.

This book includes 50 original creatures, all featured with full-page color illustrations,
system-independent stats, and thorough creature descriptions. This publication is
primarily a resource and tool for role-playing games, but fans of fantasy creature art
are also likely to find it rewarding.

The idea behind this project was to create a fantasy bestiary free from "fill-out"
creatures like bears, black oozes, dinosaurs, and "gray wart-goblins". Every
single creature should be interesting in its own right, and every interior
illustration as fine as the cover art itself.
