Eslin is a fantasy gaming world offered as a companion world to Epic RPG. It has (three in the current Atlas of Eslin volume) eight realms, any one of which can host entire campaign. Each realm in itself contains many player races, many nations, and opportunities for years of adventures. One highlight, which is a highly-touted aspect of Epic RPG, are the 30-or-so guilds described in each major realm, from which players may choose professions for their characters. This feature alone, combined with the carefully-thought-out settings developed over a decade or more of gaming, make for an exciting and worthwhile gaming world.
