Listener

Listener was one of three known thralls of the Afterkind, serving second-in-command to Thraez during the Third Emergence. He was, as his name suggests, the ears of the Afterkind, and was gifted the ability to hear anything he wished no matter the distance or volume.

Physical Appearance
"...on the leader's left flank hovered something like a man, gleaming white where Thraez burned black, blinding in radiant majesty. It should be an angel, some might've thought, but the Listener had come to no-one's aid. Sat upon the shoulders of a star-bright suit of armour was the shape of a miniature castle tower, neckless and without pivot like a frozen chess piece. Its body did not move, breath nor twitch; it was a floating cage, but what being it encaged could not be seen nor heard. It only listened."
