From the back cover:

"The Atlas of Eslin is an imaginative and exciting fantasy setting for the Epic Role Playing game system, but contains none of the stock elements that have dulled the genre. You'll find no elves, dwarves or orcs here! This volume contains three complete, different and geographically huge realms for Epic RPG adventuring and campaigns. Rullaea is the home of high feudal societies, the "godless" Pentonite religion and the twin scientific forms of magic - alchemy and metaphysics. Rimenor is the land of the primitive Fosts, filled with icy fjords, unexplored wilds and death or triumph on quiet fields of snow. In Ursyos-Elkinon, humans are subjugated by dread overlords called the Buruk, who wield powerful mind-magic and deadly serrated swords. The Atlas is packed with culture and realm-specific professions for players. This book is one of four core rulebooks for use with the Epic Role Playing game system."
