The Game of Death (Soul Eater Fan Fiction)

Raven and Dove come to Death City, bringing trouble in their wake. Both turn out to be weapons, but can wield almost any weapon so they also can be called Meisters. Both are instantly powerful, smart, and physically and mentally fit. Or so it seems. One has a issue with a incurable illness, that the other, for all her healing power, cannot heal. They hide so many secrets and will those secrets, if not reveled in time, cause mass death? No one knows their family, what their childhood was like, or if they even had a last name. Soon, a ancient game is activated, one from so long ago that even Lord Death has forgotten, but these girls know way to much. What's worse, the games dark nature rouses Raven's madness, turning her into what she truly is. Can the sisters, with their new friends backing them up, stop the game in time to not only save their lives, but the lives of everyone at Death City. And who is behind this? What will the sister, or sisters, depending on how the game turns out, do to get revenge? This will include characters and stuff from the anime, not the manga. I don't own Soul Eater, just the storyline and my OCs.
