The guess is, it's located in Osgiliath Basin in northern Erebonia.

Firstly, Giliath Osborne is from northern Erebonia and Ymir outskirts. (Sen 3)

Secondly, the name of the basin is pretty self-explanatory.

Thirdly, in Cold Steel 2's map it is originally located in south of Nord Highlands.

In Sen 3's map it "changed" to west of Ymir. It makes it more likely to think Osborne left Rean behind in Ymir after transplanting his heart to him in Black Workshop.
