“White Council… rebellions… always making a mess of the universe.” The figure said darkly. “A mess that I’ve got to clean up. Your greatest fear… you truly believe that you are the center of the universe? That you alone may throw this universe out of balance? Do you believe that so many should fall at your command?”
Voltex’s head hit the ground hard as he collapsed, weak and out of breath.
“As if they had never existed.” The figure said, pointing the rust cannon right at him. “Your punishment, then, is to no longer exist.”
