Bronik was the son of a miller. Together with other children he appears in a future scene of Chrzest Ognia (Baptism of Fire). The children live in a small village somewhere in the Northern Kingdoms. They gather round and listen to old Pogwizd. He tells them adventures from the past. He tells them in particular about a fairy-tale of the witcher Geralt and his beloved Yennefer who were looking for Ciri and he tells them of the female archer Milva.
