It was the first two pictures who resemble the Galbadia continent.
But I donīt know the location of the land of the last picture.
I played FF8 many times and never saw that land.It has a crater-like lake and part of some kind of star shaped lake.
Is this one you say that is Galbadia,Skyblade?

To The Pheonix:
Estharīs sea?No,the river is not so long(considering that you can call that little channel of water a river).Also,I compared it with the map.And itīs nothing like the sea.
