Many years ago the moon sang an enchanting so. The song was beautiful, however, what it unleashed wasn't... a simple kingdom was cursed. A lot of the people in it either got powers... or changed species. The unlucky people who were changed had gone through a lot of pain with the transformation, some even died. Not only that but more kingdoms had burst out of the ground, with different creatures controlling them. More wild "animals" had come to life. Finally the moon changed to red once a year... when it was out... people that were lucky to not be changed were not safe. Powers go out of control, animals start becoming incredibly aggressive, and kingdoms go to war.
