Centuries ago, a sentient and autonomous evil force known as the Forbidden Arts entered Earth from the underworld, intent on destroying all of its rivals for vast magical power. It learned of a legend that the Swan Princess will bring in an age of goodness and pure evil will not survive in her presence. The sentient and autonomous evil force learns that she can be defeated by a bright green-colored magical stone. The Forbidden Arts cunningly corrupted the myth, making it appear that the Swan Princess will bring despair and destruction to all instead. A group of flying squirrels called the scullions, found the legend and over the years formed a community dedicated to finding and destroying the Swan Princess. When Odette, the Swan Princess, was finally born to King William, the Forbidden Arts tried to use the power-mad sorcerer Rothbart to defeat her but failed.
