Vytal is the name of a whole continent. Ozpin mentioned Ironwood coming across the continent (halfway to be exact) but he said nothing of seas or any other part of the world. Atlas may be part of Mantle but there's nothing saying that Mantle isn't part of Vytal. Atlas and Vale may both be cities within larger regions. This would mean we have yet to learn the name of the region Vale is in if Mantle is indeed part of Vytal.

If Mantle is part of Vytal, it's possible Atlas and Vale have allied against other regions.
