From publisher blurb: World of Arkara is world setting for the OSRIC system. This is the type of setting you remember: an old-school, "Sandbox" style fantasy world with its pulp roots intact! The first in a series, the Gazetteer of the Known World provides an overview of the world, its gods, customs and social hierarchies. It includes three full pantheons of deities, new rules for making the clerics of one deity different from those of another deity, rules for social class, and a new class, the Crusader. The Gazetteer also includes four new variant classes: the Anti-Paladin, the Bounty Hunter, the Hunter and the Poacher. Variant classes take an existing class and modify it just enough to give it a new feel.
