So here is my question. Why would the ruins of lesalia be underneath rabanastre when the state of Dalmasca (and the rest of FF12) occured many millienia before lesalia was in existance? See the general Ivalice timeline here: http://finalfantasy.wikia.com/wiki/Ivalice

This to me (if this isn't just another messed up dimension or reflection but actually us traveling to ivalice) is a pretty big lore flaw.
