Artorius Vigo was a Nilfgaardian mage, master of illusions and the uncle of Fringilla Vigo. It was he who introduced her to the mysteries of magic.

Hearts of Stone expansion Edit

Although he doesn't appear, his quote is mentioned in the Ethereal bestiary entry, though the spelling is Arturius.

Blood and Wine expansion Edit

While he does not appear directly in the second expansion for The Witcher 3: Wild Hunt, it is revealed that "Uncle Artorius" had created a magical land (The Land of a Thousand Fables) for young Anna Henrietta and Sylvia Anna, which they could access by uttering an incantation while reading a magic book.
