Lanvin De Loughery is the illegitimate son of the king of Lantis. Years ago, the king had an affair with Lanvin’s mother, resulting in his birth. His mother had tried to reach out to the king, but he had denied her any attention, pushing her away. This caused Lanvin to resent his biological father to an immense degree, his hatred growing further when his mother fell ill. Just after Lanvin was born, Amadeo was also brought into the world- except he was the legitimate son and the inheritor.
