From publisher blurb:
Harness the Unseen with a new calling!
The Code of Man tells us that good dogs protect all from the Unseen. Many dogs see this as a reason to join the church and defend their homes through their faith; other dogs take a different path. Through force of personality, some dogs overcome the dangerous forces of evil to turn the Unseen's power back against itself. These dogs become unseers.
Unseers are a new magical calling that can empower their attacks and defenses with arcane power, or unleash their limited spellcasting with added devestation against evil. Some unseers learn to rebuke creatures of the Unseen, leaving them helpless against attacks!
