New races naming convention

[Seraphor]

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.
