The Age of Demons began 10 million years ago, after the end of the Age of Dragons when Khyber, the Dragon Below, slew Siberys, the Dragon Above and he was in turn imprisoned in the coils of Eberron, the Dragon Between.
But as Khyber's last act, he unleashed hordes of demons upon the world, which rose up from the depths of Khyber. The first Children of Khyber, known as the Overlords or Na-Vakti in Infernal, reigned supreme. These fiendish beings maintained personal domains on the world of Eberron for nine million years, where reality was whatever they wished.
Some 1.5 million years ago, the blue dragon prophet Ourelonastrix and couatl sage Hezcalipa rediscovered the Draconic Prophecy. Over the course of thousands of millennia of conflict with individual fiends and their forces, the combined forces of dragons and couatl were finally able to bind the Overlords. It was during this time that the deeds of draconic heroes and villains possibly formed the inspiration behind the mythology of the Sovereigns, including for the Pyrine pantheon of Sarlona that split into the modern Sovereign Host and the Dark Six. Few recognize this today outside of followers of traditions like the Church of the Wyrm Ascendant, which has followers in Stormreach and among the dragonborn of Q'barra.
Led by Hezcalipa, the couatl sacrificed themselves to form the Silver Flame, a spiritual force with the strength of a god based on the Material Plane that held the Overlords in a permanent state of torpor.
The Overlords are bound to this day, imprisoned by the couatl's sacrifice within the Silver Flame. They operate through lesser fiends called rakshasa, which are collectively known as the Lords of Dust. The aboleth fled to the lightless depths where the dragons could not reach them. Dragons such as Rhashaak were dispatched to serve as guardians over the ruins of the Overlords to ensure these beings remained bound. The lizardfolk were affected by the touch of the couatl, and dream of this age so it will not come to pass again.
Creatures of the Age of Demons
On behalf of their Rajahs, the rakshasa held sway over the lands, while the aboleth in turn dominated the deep waters of the oceans. Krakens also held sway in the ocean. The mighty dragons and couatl were the only forces that could stand united against the individual Overlords.
Other lesser creatures of the time are known to include lizardfolk, and dinosaurs. The sahuagin have legends of champions defeating the fiendish Overlords, and presumably existed in some state during the Age of Demons. Humans also existed as well, as the couatl blessed a devoted group of humans from Sarlona to become the first shulassakar and guard the couatl ruins in their absence, before the great sacrifice of the couatl to form the Silver Flame that ended the age.
