Solution 9 - Unfounded Speculation!

[Alleluia]

The massive chasm could be a recent development.

One of those 'not sure what to make of it' signs around Dawntrail for me is that the chasm doesn't have a name on the map. That thing's so big that it's very prominent on a world map, and yet it's not actually labelled.

I don't even know if that's actually a sign of something or just a bit of a quirk, though.

That reminds me. Do we know the exact location of the Ridorana Lighthouse? Cus if its situated on that chasm that crosses the new world (probably the western tip of it, closest to Hingashi.) that would not make the chasm a recent development, since the Lighthouse was supposed to be pretty old, I think? (though I suppose it depends on what you mean by "recent".) Also, it might mean the origin for the Garleans might be somewhere in the New World.

Also it means DT could tie in to Altima/auricite somehow, if it brushes against the Ivalice stuff; which we know is a bit of a dangling thread after Pandemonium.

Also, I really just want to know how that chasm can exist in the ocean and not be filled. If I had to venture a guess on the secret zone in DT, the bottom of that chasm would be one of my top contenders. Explain it, game. Explain it.
