Aut is a humanoid with completely white skin. He has oversized hands and feet, but unnaturally gangly, thin arms and legs. His torso is a simple cylinder. His head is perfectly spherical, overly large, and has absolutely no facial features expect for a giant toothy grin that stretches from one side of his face to the other.
He makes a habit of observing the world, and nudging it in the direction he prefers through his "friends." The recent advent of the Voidsong has somehow disrupted his ability, however, much to his chagrin. He lives somewhere within the Black and White.
