The Silver Principality has been accumulated for three generations, and its salt and iron benefits are unparalleled in all directions.
The northwest empire collapsed, the price of salt soared, and the principality became rich overnight. But wealth attracts not surrender, but covetousness - thieves, warlords, and enemy countries, coming like a tide.
