The King of the Wild Hunt and his specters appear to Geralt over the course of The Witcher, taunting and twisting his memories.
The first glimpse of the King and its minions occur near Kaer Morhen in the Prologue. In Chapter I it appears again in the Outskirts along with the ghost of Leo. In Chapter IV, Geralt must avoid summoning him while completing a quest for the Hermit. These encounters culminate at the end of the game where Geralt must face another major dilemma.
