I've actually been comparing this with the map WC-83 posted.

I propose two possibilities.

A.School Light

Beacon can either be in the center light or the north light, the east light takes place in a reddish environment, which is not very Beacon-like and the western light is in a desert.

B.City Light

For the same reason as above, Vale is in the center of Vytal, however, that region seems to mountainous for Vale. Which may put it's location on the north, in the greenish patch of land.

There's a higher chance it's the center light though, since Beacon is in a mountain of sorts.

Either way, this sorta pinpoints the location of either Vale or Beacon into four places. And that helps greatly.
