The Nihility — IX

"You may gaze deep into the vast grandeur of the stars, but do not glance at the abyss of the void... for it holds nothing except for the ability to make mortals lose all reason and thought."
— Murong, Doctor of Chaos

The existence of Nihility is a mystery itself, enshrouded by layers of mist.
IX doesn't interact with the other Aeons. They believe that the ultimate fate of the multiverse is nothingness, and therefore, worthless.
