The witcher Geralt of Rivia once lived in the secluded mountain fortress Kaer Morhen, where he enjoyed a peaceful life with his beloved Yennefer and, together with his fellow witchers, trained a young girl named Ciri, the daughter of Emhyr var Emreis, Emperor of Nilfgaard. Following a prolonged memory loss and other turbulent events described in his previous adventures, Geralt eventually gets close to a reunion with Yennefer, whom he hasn't seen in a long time. Meanwhile, the Empire of Nilfgaard invades the Northern Kingdoms, and Geralt is contacted by the Emperor who asks him to find Ciri. In the midst of these events, a supernatural army known as the Wild Hunt appears in the region, threatening to obliterate everything in their path towards an unknown goal.
