Well, logically, the lands of Caligus were once nominally part of the Greater Xavaxian empire, so the new realm in Fontan should be called North Xavax.
Then if the Sirionite Xavax ever get their own realm they could call it True Xavax.
So you'd end up with 'North Xavax' being to the south of the other Xavax. Should make the map interesting (confusing) 
So like how Eponllyn is a southern realm living way up north, after the glaciers?
