Vadderung

The Vadderung is an archfey of the Autumn Court of the Feywild. 
He appears only when the Wild Hunt rides, and sits at the right hand of the Erlkönig. He is nearly as tall as the Erlkönig, with a scar over his right eye and a dizzying variety of axes, spears, bows, and other weapons. He rides on the back of the beastlike archfey The Void.
