From publisher blurb: The fight against good is a tiring but satisfying business. While some are called by the dark to be drive forth the spread of evil, many other competent soldiers fill the gap to take up arms against those that commit the most honorable of acts. The soulless heart combines the martial focus of the fighter with many of the profanely vested gifts of the anti-paladin to aid in their never-ending quest to overcome the light. This supplement also includes new feats geared for the soulless heart's special abilities.
