Eberron

Eberron is a world in which magic and science are one. Magic pervades the life of every civilization, but truly exceptional magic is rare and valuable. The Last War, and especially the cataclysmic Mourning, have left their mark on the continent of Khorvaire and its denizens. Unknowingly, a small group of adventurers is about to be swept up in political intrigue, inter-planar conflict, and an ancient prophecy.
