Vanhemar (d. June 1271) was a Nilfgaardian fire mage, Cynthia's master and personal sorcerer to Ambassador Shilard Fitz-Oesterlen, whom he accompanied as part of the Empire's delegation. He died in a fight with Geralt when Ambassador unwisely left him to "finish off" the witcher while the delegation fled to Loc Muinne to attend the summit.
