In the 'Swan Lake' short story, Odette is a key character. She is a princess cursed into a swan form. Prince Siegfried is another main character.

His actions drive the conflict in the story as he tries to prevent the prince and Odette from being together.
The main characters are Leda and Zeus. Leda is a mortal woman, while Zeus is the king of the gods. Zeus disguises himself as a swan to approach Leda.
The main character is most likely the dark swan. But there could be other important characters as well. Maybe there's an older, wiser swan that acts as a mentor to the dark swan. Or there could be a group of swans that initially reject the dark swan but later come to accept it. And who knows, there might be a human observer in the story who plays a role in the dark swan's journey, either by helping it or causing more difficulties for it.
