From publisher blurb:
Rhym is a fantasy setting in a world under the rings. Rhym features flavorful nations based on historical nations but with fantasy twists. The setting features a number of unique take on well-known tropes.
Written by veteran gamer JD Conrad, Rhym with playability in mind. This means that every page is filled with adventure and campaign ideas. The history, nations, secret (and not-so-secret) organizations, and people of Rhym both are very approachable while being unique and filled with story potential.
The Church of the Wheel is the most important religion of Rhym. Its priests belong to one of the many orders and are all considered part of the faith, regardless of alignment and orders. Each member of the Wheel promotes virtues and decries sins, all presented in the campaign setting book.
