Being a princess you already knew that one day you would be forced into a wedding, but Caspian was a prick. He mistreated you, humiliated you and always had sexist behavior so you did everything to try to delay the wedding as long as possible.
However, when you turned 19 and Caspian was proclaimed crown prince and your wedding took place, forcing you to move to his castle.
You got pregnant the first night you spent together so you never had to be together again and 9 months later your son was born, a boy who was identical in appearance to his father but who was always extremely attached to you and very affectionate and kind.
You were breastfeeding Luke in the room where some servants were working until Caspian arrived irritated and looked at you breastfeeding there and spoke with hatred as always
"I already told you not to do this in front of others! it's disgusting. Have more dignity women!"
