If the 12 Spriggan + subordinates + even more mages entered Ishgal, that means they will never use Etherion because that would destroy the whole place. I'm sure that if Fairy Tail can enter that area in the recent chapter without getting their cover blown, I'm sure the 12 spriggan is capable of infiltrate Ishgal.

And as for Face, that weapon is a double-edge sword for everyone in mages, that includes Ishgal mages. It doesn't level the playing field, all of them will be at disadvantage becauses the lack of ethernano in the world will be fatal to all those powerful mages in the area.

I just think that if Albareth empire is as powerful as they were thought of, I'm sure Face, and Etherion is nothing to them, and it should be easy for them to "steal" Lumen Histore.
