| The high spirited Commander of the guards of Lake Castle.
— Cecile's profile
Cecile is a brave girl, filled with boundless energy who served as the gatekeeper of Budehuc Castle. She had unofficially taken over the position after the passing of her father and previous guard commander, Brown, but was appointed as the official gatekeeper with the aid of Salome Harras shortly after Thomas took over the administration of the castle.
Thrilled at her official status, Cecile dedicated herself to protecting Thomas through the War of the Champions and aided him in rescuing his namesake from Mt. Hei-Tou. She would continue to support Thomas when Budehuc Castle became the base of operations of the Fire Bringer.
Cecile is also known to be a good cook, although Thomas fainted when he ate Cecile's food, as he wasn't used to her taste for hot and spicy foods. She formed a friendship with Emily and often trained with her. She also became friends with Alanis, who admired her strength and kindness.
Caesar Silverberg, however, wondered if it was appropriate for Cecile, and the dogs, who later served alongside her, to work in such an important position. Although Cecile liked having the companionship of the castle dogs, she acknowledged that they were useless as gatekeepers because they did not bark when anyone approached the castle grounds.
Cecile did write letters to Hugo on the dogs' behalf, however. She also wrote several letters on her own, mostly sharing how she got through the weather of the day, noting that being the guardskeeper in the rain was hard, but that she would try hard for the castle and that she didn't like cloudy days.
She got into a confrontation with Branky, Mel's foul-mouthed puppet, and almost stabbed it with her spear. Cecile also showed admiration for Chris Lightfellow, wishing she could hurry up and mature herself.
Following the war, she and her three subordinates (including young Thomas) continued to keep the peace at Budehuc Castle.
