In the final battle against the Wild Hunt, Harry is thrown back to when he was eleven years old, arriving at the beginning of his story in the wizarding world. Now, as memories of his Witcher training resurface, he realizes the source of his unique power—the strange magic that wizards call spells and Witchers call something else entirely. A Witcher? A wizard? Fine…if he can wield a silver sword, adding a wand should be no trouble at all.
