The beautiful and lascivious daughter of Gralon, King of Ker-Ys. She stole
the keys of the sluice gates from her father and presented them to her lover, who let in
the waters of the sea. Her father fled the flood on horseback with Ahes on the crupper
behind him, accompanied by St. Guénolé, the king's confessor. When the
water tried to engulf them, the confessor bade the king to cast off the she devil who had
caused the mischief. At these words, Ahes fell with a shriek into the waves and
disappeared. Her father reached dry land, but Ahes still haunts the seas in the form of a
lovely maiden, luring sailors to their doom.
