Theralind was the beloved of Corduin of L'Anguille, first Duke and Grail Companion. Legend has it she was transformed into a hideous sea-monster by a jealous hag, but her natural virtue triumphed and she now guards the port. The fierce, unpredictable storms that lash the coast are said to be the result of her grief, and it is true they almost never strike L'Anguille itself nor the shipping channel leading to the port.
