Once upon a time, there was a princess named Little Snowdrop, who had six brothers and four sisters. Her brothers were ravens, and her sisters were swans. Whenever they wished, they would fly around the castle on their black or white wings, but Snowdrop, not having any wings of her own, could not join them. She could only wave at them from the window of a high tower as they flew by. Her father was the King, and he loved her very much.
