Demons and Destinies: A Story About Fate, and Freedom

Two Princesses. One lives in a golden castle, one lives in one of dark stone. Both are trapped. One is told her heart must be locked away; one is told her heart should be filled with light. When a ball brings them together, and things go horribly wrong, they collide, each of their ideals of what they should be clashing. Both prisoners in spirit, and then fugitives as they're hunted down across kingdoms. Lines blur and alliances are forged and broken, and bonds break and friendships fracture. They're always been told they have a fate; they were born into this role, and they will fit that role. But as they witness the world outside of the palace, it becomes harder and harder to fit that role, and they must choose between fate or freedom. Obidence or wildness. Discipline or feralness. Enemies... or friends?
