The world of Eberron has a rich history built on heroic deeds, evolving magic, and the wounds of a long, devastating war. In the wake of the Last War, action, adventure, good, evil, and a thousand shades of gray paint the landscape in broad, powerful strokes, and ancient mysteries await discovery so that they too can influence the world and its people.
The medieval world of Eberron is place of magic and monsters, where arcane energy infuses the landscape and greatly influences society and industry. Thanks to a mastery of the arcane arts, the great cities of the continent of Khorvaire contain skyscraping castles, elemental-powered coaches and carriages, and all manner of enchanted conveniences. Magic is industry across the face of Eberron, the innovative spark that propels society forward.

The Dark Side campaign will focus in the newly formed nation of the Eldeen Reaches. On the edge of the Towering Wood, with only the Shadowcrag Mountains as a barrier for the Demon Wastes, lies a small village by the name of Fellcrest. Fellcrest has a small council to make decisions concerning the community and the spiritual leader is an elven druid, Nemata. The Warden of the Woods have a half-orc ranger, Brock, that patrols the area constantly watching for aberrations from the Demon Wastes.
