I did not fight Eden in FFVIII, so I don't know if this is something peculiar only to FFXIV's version of the guardian force:




Eden's limit break summons a force field around a planet, arranged in twelve directions.

Is that coincidence? Or is it a subtle hint of the Twelve? My current theory is that Hydaelyn was summoned by a rebel group of 12 Ascians, in opposition to the summoning of Zodiark. Perhaps Eden was also created by the rebel Ascians, before the fall of Amaulot?
