Clair is a Pegasus Knight of Zofia and the younger sister of Clive and childhood friend of Fernand. Despite resistance, Clair joined the Deliverance, she was accepted as a knight after she asked her father permission to fight alongside her brother. However, she was captured by Desaix's men and was held captive until Alm and Lukas rescued her. Clair rejoined the Deliverance and fought alongside her brother and the group to overthrow Desaix.
She is shown to have a small crush on Alm in Gaiden, joking that Alm was the one she really wanted when Gray won her over. In Shadows of Valentia, Clair and Alm's relationship is expanded and generally portrayed as platonic on Alm's end. She backs off once she witnesses how close Alm and Celica are. The two become very close friends as the game progresses.
Throughout the game, Clair is courted by both Gray and Tobin, causing some rifts between the two friends. Ultimately, Clair chooses to wed Gray after the events of the war.
