Kingdom Hearts Zero Hour

A short roleplay I'd like to develop that centers around Kingdom Hearts, and the creation of the X-Blade. There's already plenty of lore surrounding the kingdom hearts franchise, but I was curious about what happened before the keyblade war, and how kingdom hearts came to be such a sought after entity. The roleplay would be for up to twenty people taking the roles of the original seven lights and thirteen darknesses.

Story
Back when the worlds weren't separated, the land was rules by seven sisters. Princesses in fact. Each maiden explored the land, offering gifts and spreading teachings that would bring out the most light in people's hearts. These seven beautiful maidens were powerful and kept peace in the world in their own individual way. Despite keeping light alive and well, they rarely got along and had disagreements with the quality and subjects of their teaching methods. As such, they kept to themselves and rarely interacted with each other.

This story occurs at the very beginning of the age of fairy tails, and exists before the creation of the keyblade and assemblage of the foretellers, so the land was ruled and peacefully lead by the seven maidens until the day of darkness arose. The Lord of Darkness arose from the shadows with his 12 knights to create chaos in the world. In a short time, the band of thirteen had introduced darkness into the world. Alone, the maidens were no match for the knights of darkness. As such, they vowed to unite their efforts and challenge the newcomers of darkness to a clash.
