you cannot call for love like a dog

When Geralt is drawn into a new world, he is startled to discover that his old memories have mingled with new ones - a world where he was once married to Yennefer and adopted a child named Cirilla, affectionately nicknamed Ciri. He is also surprised to find that among his new ones, not a single memory of Jaskier exists. Naturally, Geralt must get to the bottom of this - how did this new world come to be? How is it he is the only one who remembers his world as a witcher? Where exactly is Jaskier, anyway? And perhaps most importantly, what is the true purpose of creating a world in which witchers do not exist?
