Lac Célavy is a lake in the Gorgon Foothills of western Toussaint, south of Chuchote Cave. It is the home of the Lady of the Lake in this part of the Continent.

On a small island in the middle of the lake, a hermit meditates and guards stones inscribed with the five chivalric virtues, while the Fisher King fishes along the shore. The lake is the setting of the side quest There Can Be Only One, which leads to the legendary sword Aerondight.
