Rivalry!!

So, as the title says Luna is gonna need a rival somewhere down the road to challage her ideals, her morals etc.... its likely, as of now that she'll end up trying to prevent the keyholes from being sealed in an attempt to prevent places, such as her home world from being sealed off from the rest of the worlds, something she'll think makes them vulnerable (she knows a bit about the heartless, but figures she can protect them from the creatures on her own, or sacrifice to do so, whatever works)

So! Any takers?
