Hydaelyn, and Zodiark's interactions with the other shards. [Theories]

[DamianFatale]

I have three theories on Hydaelyn, and Zodiark on other shards.

Theory one:

When Zodiark, and Hydaelyn split, they split into fourteen different versions of themselves. Is each worlds name Hydaelyn? We still don't know if Norvbrandt is the mirrored planet, or just mirrored Eorzea itself. If the citizens of the first shard do indeed call their planet Hydaelyn, then I assume Hydaelyn and Zodiark can interact with all of them as if there is no split. Perhaps each "shard" of themselves can be used as an aetherite, and the crystal tower is an antenna to the center of each reflection, so that they and all who unlock the stream of aether can "connect" to each world in this way. It might be possible that the Allagans merely added onto the tower. The tower could predate the Allagan Empire. It might also explain why it would exist on the first.

Theory two:

Each shard became its own crystal god of each planet, and has independent influence of each other.

Theory three:

That Zodiark, or split versions or him are in control of at least one or more of the shards. Just because Hydaelyn won the battle for the time being, may not prevent Zodiark's dark influence from freeing himself on another. Perhaps that is also why some fall to dark, and some fall to light.
