Konachna Fortress was built as the border between the Eternal Empire and the Duchy of Exemplia became ever more militarised, before the Duchy was formally annexed some time in the early 17th century. It is home to the IV. Grenadier Corps of the Imperial Army, under the command of G.C.A. Callisto Merola.
The Konachna Fortress trains Grenadiers. Training takes 1d6 weeks and 10 doubloons per soldier.
