From publisher blurb:
The Exorcist Domain intervenes against unspeakable horrors, chaotic fey and well-intentioned celestials who seek to possess the innocent for their own intentions. Members of this domain evict extraplanar incursions from a person or an area and stand ready and willing to face the creature that emerges head-on.
Clerics who excel at banishing evil from whence it came, understand that corruption manifests in unexpected forms. Not only must they expel the corruption, but also uncover it under layers of lies and deceit. Followers of these gods take great pride in maintaining the tools necessary for their work. Their armor and religious garments are inlaid with sacred texts, holy scripture and religious iconography. They speak with purpose and duty when the task is at hand and may even paint or mark their bodies for added protection. A veteran exorcist is a prime target for powerful horrors and hidden cults.
