The Abyss, a small independent Multiverse with its own Consciousness, froze for a moment, then every world, dimension, Floor and hidden space started to shake, as if the Abyss was being shaken by a higher being.
The reason for this was a sound that reverberated multiple times all over the Abyss in an echo of pure rage, ambition and pure hate, " SCREEEEEEEEEEEEEEEEECH !!!!!! " Every being felt it, as if a banshee unleashed her cry directly into your brain.
The owner of this sound, was a being believed to be forgotten, a creature so old it predates the formation of the abyss's consciousness, one of the fist demons to ever spawn in this realm, and this demon was a she, her age unknown, her realm untouched, her existence hidden by reality itself, she was one of the Exceptions of the Abyss.
