Wretched Folklore

From publisher blurb:

On its face, Wretched Folklore it is a bestiary of creatures inspired by both Native American and European folklore to use in your Wretched Country and Wretched Époque campaigns. As games written with the OSR in mind—or, more aptly, written with the OSR game design philosophy as a guide—the Red Room’s offerings can fit into just about any game system with very little tweaking. This supplement, Wretched Folklore, is no different. You will find monsters that are, hopefully, unique and not your standard critter found in a monster manual of the world’s most popular role-playing game. Perhaps one of these monsters will make a fitting substitute for a creature found in a module of your own.
