Abyssal Plane

"Against all the evil in this world, all the wickedness that this land hath wrought, there will be more deep below; the force of the abyss knows no end, knows no bounds, it is a pure entity of chaos and dismay... You must enter into its heart, and you must tear it apart... vein from vein

...Until it is done."

The abyss is the manifestation of chaos, enemy to the Cosmos, and the father of the soul.
Since the beginning of life on Tellus, the force of the Abyss has been at the core of it all, it is what drives forward the primal instinct of survival, through any means necessary. The Abyss grants free-will and adaptation, as well as imperfection, emotion and chaos.
