World of Fiends

Era beginning/end

The Rise of the empire of the Overlords.

Ten million years ago, fiendish offspring of the Dragon Below—the rakshasas, night hags, demons, devils, and the Na-Vakhti or “Overlords”—the rajahs of the rakshasas—burst forth from the deep darkness of the Dragon Below and overran the surface world, creating a hellish environment where rakshasas and night hags ruled supreme. The seas of Eberron, the Material Realm were a little better, having become the domain of the alien aboleths. The aboleths were also children of the Pheonix above, having arrived on Eberron, the Material Realm from Xoriat, the Realm of Madness, the Far Realm. Just as the fiends built hellish kingdoms of nightmare over most of Eberron, the Material Realm's surface, the aboleths established their own bizarre and incomprehensible dwellings in every major ocean and sea of the young world.
