A group of mystical creatures known through the East as "The Black Swans", come across a young girl in The Black Forest. She has secrets, and so do they. As the Swans encounter her more and more, it's clear she's special, so they take her in. When she reveals some of her secrets, it becomes clear that she's got a part to play in the Swans' plans. Will she be able to help them? Or will she stab them in the back?

she finally got the courage to go to the attic and clean up the place. she found an old chess board that looks like its not been touched since ages. being the playful person she was, she put up the chess pieces in their places, on the board, and moved a piece from one of the sides. her phone rang and she went to the hall to talk. she got distracted and forgot that she had to clean up the attic. the next day, she remembered about cleaning up and went back there to finish her job. and when she entered the attic, she noticed one of the pieces from the other side had been moved.
