The Old Ones are the extremely powerful, pure-breed demons that once dominated Earth before humankind appeared. The Beast is thought to be one of these demons and a being named Illyria his lover.

"This world is older than any of you know. Contrary to popular mythology, it did not begin as a paradise. For untold eons demons walked the Earth. They made it their home, their...their Hell. But in time, they lost their purchase on this reality. The way was made for mortal animals, for, for man. All that remains of the Old Ones are vestiges, certain magicks, certain creatures..." --Wyck

The Old Ones possess many different shapes and powers, but all of them are gigantic. They were worshipped as gods, ruled over vast territories, commanded fearsome armies, and constantly made war against each other. They also did not seem to live and die the way mortals do. In short, under the Old Ones' rule, the world was a living hell.

At some point, the Old Ones lost their claim over this reality; some were killed while others were driven from this dimension. The corpses of the greater fallen Old Ones were placed deep within the Earth and forced to live as forms of black smoke. The last Old One to leave this world fed from a human, therefore mixing its blood with it. This resulted in the first hybrid demon: the vampire.

In the centuries that followed, the Old Ones continued to be objects of worship among the lesser half-breed demons.
