Great uncle to the current Queen Domitille and married to Onésime Voclain, Kilian was the surprise child for Sacha and Calixte. He is very conscientious and kind, and it is said he fell in love with his husband at first sight. They had some resistance to their marriage at first, considering he would not be carrying on the family name with a child, but the resistance melted away under the blazing approval of his sister Jehanne, who was Queen at the time. He met Onésime by chance at the palace when Onésime was accompanying someone else who was petitioning the Queen. He mourned his sister’s death quite heavily and is on good terms with his brother Mathys and the remaining members of his own family and that of Onésime’s. Kilian really likes cats.
