Long ago in the kingdom of Tavensis, two twins were born, respresenting the peace of Tavensis. But when war broke out, the king and queen were killed. The angel queen adopted the black haired twin, while the demon queen adopted the white haired twin. And the twins' name were Yin and Yang. In their kingdoms, they were said to be the most beautiful twins ever seen.

But, it was very gloomy living in the castles' because both of the queens' had daughters. The demon queen had a daughter named Anastasia, and the angel queen had a daughter named Fiona. They were not very welcoming to the twins either. (yang is white and yin is black) They were snobby and spoiled. But atleast they would have their step mothers.
