Caelum Kingdom was mentioned one-time during the Council's heated debate of using Etherion near neighboring nation next to Fiore in the Tower of Heaven arc but yeah Bosco was a far better country mentioned often times.

Such a shame Mashima didn't even bother expand more about Ishgar's countries. Damn the names of them are interesting to look at. It wouldn't hurt to world building everything in FT universe, not focus on a one small country alone.
