From publisher blurb:

The Codex Arcanis is the essential tome for the critically-acclaimed Arcanis: the World of Shattered Empires campaign setting. Within one will find:

• The History and geography of each of Onara's great nations
• Races, feats, and prestige classes - all approved for use with Living Arcanis
• A complete pantheon, unlike any fantasy religion in that it is left to mortals to interpret the commandments of faith, as it would be with any realistic faith

Thousands of people world-wide play in the World of Shattered Empires, and now's your chance to join them.
Mortals stumble in darkness; heroes light the way. Be the hero, Leave Your Mark upon the Shattered Empires.
