In the neighboring kingdom of Clonmel, a mysterious cult, The Outsiders, has sprung up, promising defense against lawless marauders in exchange for people's riches.  Their sermons attract audiences from miles around, but there's a dark side to this seemingly charitable group, prompting Halt, Will, and Horace to investigate.
