The Firstborn were there when the world was created, maybe even before. Beings of immense power and knowledge, the Firstborn stood over creation as demigods, lording or feeding on the lesser creatures. But the Firstborn are not omnipotent, over countless millennia, any semblance of sanity they had faded away with the greatest of their powers. They are now (for the most part) sleepwalking superweapons, driven by basic instincts and animal desires. Very few have managed to escape their decline, hiding in the darkest corners of the world.
