A sweet-tempered sister of Mila, Silque became a cleric because of her mother's influence, who was also a cleric. It is later revealed that her mother was in the service of Duma and suddenly crossed the Zofian border; leaving Silque in a Zofian monastery and disappearing. Though not knowing her reasons, Silque began to dedicate her life to save people from suffering; believing this is her purpose in life.

She was then kidnapped by Thieves, who forced her into their shrine, later being rescued by Alm's group and becoming their healer. In Echoes, she entrusts Alm with Mila's Turnwheel.
