New races naming convention

[Daralii]

if au ra is anything to go off i really doubt we will see many NPC hrothgar or Viera in ShB and we wont know much about them till a expansion later

We've known since Paris that Rak'tika Greatwood is the home of the First's Viera(Viis).

Well it's implied it's home to the Viera, but we don't know it's on the First yet.

It's also home to the Nu Mou and they're mentioned in the Return to Ivalice lore, which would indicate they're on the Source.
We've seen Rak'tika with a day/night cycle.
And the scene with Uriangier and Y'shtola/Matoya seems to imply it's on the Source.

All of the zones are on the First. I think Yoshida actually confirmed that in an interview, but if he didn't all of the zones shown so far have the same new unique aetheryte crystals, including Rak'Tika. We haven't actually seen a day/night cycle in the Rak'Tika trailer, it could just be the canopy blocking the sky.
