The League Principality is a vassal or tributary state of the Empire located to the east of the Kingdom of Alguna and the west of the Kingdom of Elbe and Toumaren, on the large peninsula south of Falmart (the same one as Elbe, Sadera, and, Alnus are all located on). The mountain range of the Tuba Mountains runs south to the borders of the Principality.
Not much is known about the League Principality military, however, it can be seen that much like the Kingdom of Elbe, the people of League has modeled its military after the one of the Empire. Some of the major differences is that the military is dressed in green with yellow trim, as well as the Emblem of the League Principality on the tops of their helmets.
The armies of the League Principality were present at the Battle of Alnus Hill, where they, along with Mudwan and Alguna were the first to advance on the JSDF positions. The troops of League, along with the armies of Mudwan and Alguna, were destroyed in the first artillery barrage, resulting in the death of over ten thousand soldiers, including the Duke of League himself.
