So it's apparent we'll at least see Mithra and Galka (look at the screenshots from the stills of the cinematic on the teaser site if you haven't seen already).
Here's my thing, so it's not Vana'diel, right? It's a different Land. That means it's all part of the same planet? What other lands encompass this place?
Forgive me for not being lore-savvy. I have hardly even been through most of the game missions.
