[Source] Baron Lambert Hus-Roy from Vengerberg was an Aedirnian nobleman whose wife was, sometime prior to the Second Nilfgaard War, turned into a falcon by some curse. Nobody believed him however and people were claiming he has gone mad until Triss Merigold performed a ritual and managed to reveal that the falcon was indeed baron's wife. Sadly, the curse was not reversible. Baron was thankful nevertheless and gave sorceress reward.
