Key to the World
A hymn of destruction. A song of invasion. Carol was the calamity that the former Princesses had once driven away, and which the Red and White Queens feared would return. A natural phenomenon devoid of any human intent or malice, destined merely to obliterate all that exists. As a result, the worlds of Alicepia and Minamo's have merged, and Jammerwocks are appearing endlessly throughout the city.
