The name of the King of the Wild Hunt, the identity of the lord of nightmares, the being behind the frightful mask - this long remained unknown. Over time, however, scraps of information gradually coalesced into a full likeness of Our foe - but did nothing to detract from the terror he inspired.
The Wild Hunt was in truth an elite cavalry brigade from the World of the Aen Elle, the Alder Folk, and was commanded by their ambitious and ruthless king, Eredin Breacc Glas. He would travel via secret paths through the cold emptiness between his world from Ours to capture victims and take them back to his homeland as slaves.
The current object of his Hunt was Cirilla, whose power he wanted to harness for his own uses. The only obstacle in his path-Geralt of Rivia.
Ciri was able to shed a bit of light on the commander of the Wild Hunt's motivations. The threat of annihilation hung over the Aen Elle homeland. Eredin, a warrior and a conqueror by nature, decided to solve this problem in the simplest possible way - by seizing our world. The key to doing so Ciris power, which would allow him to open the gates to a full-scale invasion.
