Unversed: Empty Hearts

[Horizon's Knight]

This could work, although I don't think all Heart come from Light, seeing as most Hearts have Darkness in them. Other than that, this is a very great theory.

Basically what the theory says is this:

Unversed are made out of empty hearts.

Hearts born from Kingdom Hearts are granted light, and as established throughout the series, the light in hearts can never be extinguish. However, Master Xehanort finds a way to create hearts from nothing that start out with nothing. These hearts never had any light to begin with, so they are able to exist in a state void light, darkness, and memories. A state of complete emptiness.

Nothing can enter these hearts, so they will always remain empty. However, these hearts are able to wrap themselves in the power that radiates from hearts of others. Those whose hearts hold negative emotions might emit some sort of aura these empty hearts are attracted to. These empty hearts feed off these negative emotions in order to materialize a physical form and augment its power.

Since the Unversed are a product of Master Xehanort’s own power and influence, if Master Xehanort disappears from the picture, then there wouldn’t be an individual commanding empty hearts to come into existence and producing the Unversed. Therefore, the production of the Unversed would come to a halt. And as for all Unversed already produced, if Master Xehanort’s power is thwarted, then the hearts born of nothing may just unravel and become nothing.

Or maybe the empty hearts will simply no longer be able to function as active creatures without the power of their creator sustaining their existence, and thus all fade into Kingdom Hearts, due to the nature of the great heart to absorb all matter into its depths.

There's also some other details in this theory about the symbol, possible relations to the Heartless, other things about the Unversed. I tried my best to keep it as short as I could, so I think it would be best to read it to get the full idea of what the theory is about.

Well the idea is that the true essence of all hearts born from Kingdom Hearts is that of light. These hearts are born of light, and always contain light. However, most all hearts allow things to obstruct their light within, thus allowing traces of darkness to exist in these hearts.
