The Inner Sea region is the trading and cultural hub of two mighty continents—Avistan and Garund. At the heart of the Inner Sea’s warm waters stands Absalom, the City at the Center of the World. Founded by the living god Aroden, this ancient island city-state has survived nearly 5 millennia of toppled kingdoms to thrive as a haven of merchants and scoundrels. In the west, the Inner Sea passes through the narrow Arch of Aroden, a tenaciously contested strait named for the monolithic, ruined stone bridge connecting the two continents at their closest point of approach. To the east, the Inner Sea opens into the vast Obari Ocean.
The two continents that frame the Inner Sea are very different from one another. Avistan, to the north, is the seat of once-mighty empires like Cheliax and Taldor, and site of the ruins of Lost Thassilon in the frontier realm of Varisia. South, across the wide waterway of the Inner Sea, lie the secrets of Garund, a sprawling continent of arid deserts and fecund jungles, where the mighty pharaohs of Osirion emerged from the Age of Darkness to chart a new destiny for humanity.
Generally speaking, civilization centers on the Inner Sea, with barbarism and savagery taking hold where the sea’s refining influence wanes. Exceptions exist, of course, and the scattered lights of civilization stand out in the dark wildernesses and savage frontiers far to the north in Avistan and well to the south in Garund. Likewise, dark, wild areas exist within otherwise civilized lands close to the Inner Sea. Mercenaries and would-be heroes seek fortune and glory throughout the Inner Sea region, uncovering lost treasures, pacifying terrible dangers, and finding ignoble deaths in every unclaimed wilderness, kingdom, and empire of Avistan and Garund.
