where is that waterfall????

[Speeral]

if you watched the Cinematic Intro Movie to the game you'll notice those waterfalls are where they fought the Morbol, and below where the Garlean Warship + Dragons were fighting. The Warship + (Dragon/Bahamut) fell into the area and released a bunch of Aetheryte + Primals. That area is now Mor Dhona. Waterfalls are now Mor Dhona.

Actually no, the original morbol battle and flying ship encounter was one area.
then the scene moves and the protagonist the hume wakes from being out cold for a while.
its not mordhona re watch that vid.
