I have a theory of what's in the box that the Master of Masters was dragging. I think it might be the 13 pieces of darkness of the shattered χ-blade. The χ-blade shattered into 20 pieces: 13 of darkness and 7 of light. We know that it broke into 7 pieces of light in order to protect the hearts of the Seven Princesses of Heart, but we don't know exactly what that means. Especially considering the Seven Princesses of Heart weren't alive way back then. But maybe it means that the χ-blade shattered into 7 pieces of light which would then become the Seven Princess of Heart's hearts in the future? Also, we were never told what happened to the 13 pieces of darkness. If a heart of pure darkness and a heart of pure light clash, then the χ-blade is recreated, but it is unstable. In DDD, it is revealed that Xehanort plans on capturing the Seven Princesses again so that they can clash with the 13 Seekers of Darkness to recreate the χ-blade. But, how can this be? The 13 Seekers of Darkness don't have hearts of pure darkness, so how would them clashing with the pure-hearted princesses recreate the χ-blade? I think I might know the answer. I believe that Xehanort wants to find that case that the Master of Masters has or maybe he already has it. If the 13 pieces of darkness from the shattered χ-blade are in that case, then Xehanort can take them and put them into each of the 13 Seekers of Darkness' hearts to turn them into hearts of pure darkness. Then, he can clash with the Princesses of Heart to recreate the χ-blade, but this time, a much more stable one. It'd actually pretty much be the original χ-blade because it'd be created from the original shattered pieces. So yeah, what do you think of this theory? Anything I could add to it?

Chirithy says they were given new names by the Master of Masters which are the names they use now. Do you think we will ever find out their true names? What would be the point of adding a story detail like this without having us eventually find out their true names?
