In the fantastic land of Markovy east of Europe, in the Iron Wood filled with werewolves and other unpleasant creatures, in the house of the dreaded Bone Witch, lives a young orphan girl named Aria. Her life is changed forever when a foreign knight, Sir Roye de Roye, enters the forest pursued by enemies, carrying with him the most precious artifact of the kingdom, the egg of the Firebird. Aria saves him and falls in love with him, and it becomes her mission in life to restore the egg to the firebird's nest. And so she and her knight set out on a wonderful quest, filled with spectacle, romance, and hair's-breadth escapes, to save the land and find a life together.
