At its height, Arkhosia was a center of learning for arcana, religion, history, philosophy and mysticism. Its treatises on these subjects have yet to be surpassed in the Current Eon, and those few extant works command astronomical prices among scholars. While it was relatively small in area (comprised of only seven cities) compared to contemporary nations such as Nerath and Bael Turath, the influence it wielded was unparalleled in matters academic and military.
Arkhosia was at war with the tiefling nation of Bael Turath when both were destroyed in a terrible cataclysm.
The capital and most prominent of Arkhosia's fabled seven cities was Dendrith.
