From publisher blurb:
Bloodwraith is a stand-alone, self-contained fantasy setting for any roleplaying game system, specifically ones that focus on gritty or low-tech fantasy. This book is about the rules of bloodwraith, with classes, combat, and monsters all brought into play. New rules for community building and drama points are included in this otherwise Coin and Blood, OSR homage.
The adventure challenges of this game world focus on survival and dealing with the world in front of the characters, than dungeon-delving and super-heroics. That won’t stop people from doing those things in this world, but that is not the intent of this game world.
