Where are lalafells from again?

[Frederick22]

The truth is that the races have come on gone, rose and declined, for 10,000 years. Just because the Elezen were basically the "sole inhabitants" of Eorzea in the early Sixth Astral doesn't mean there couldn't have possibly barely been any in Second Astral Era times.

But Anonymoose, not that most of Mhachi's habitants were lalafells. Arent they the ancestors or Uldah? Doesnt surprise me if there were hyurs too, specially hyghanders ( hyghander statue on the void ark )
So by the time of the 5th astral era, there were already hyurs, elezen, lalafells and miqotes too ( miqotes came on the ice age or even before )

Why you are saing that elezens were the only inhabitants of eorzea on the early 6th astral era? o_o
