From publisher blurb: What an excellent day for an exorcism! Doctor Diomedes is one of the most successful and popular exorcists in all of Zul. The wealthy and powerful seek him out to rid their loved ones of hostile spiritual possession—but he has a secret that only his half-orc partner in the healing arts knows about. And with a bounty on his head, there'll be Hell to pay when Doctor Diomedes comes to Vadashar. Included is a brief history of the Free City of Vadashar, plus character descriptions, an essay about medicine, healing, and the supernatural causes of illness, the mechanics of demon possession and exorcism in the World of Zul, adventure hooks, NPC stat blocks, and advice for incorporating Doctor Diomedes into your campaign.
