The Accordance War started in 207 NDE when a conspiracy involving the Brallic royal family, elementalists, and anarchists attempted to assassinate the Prime Minister of the Great Republic. The Republic quickly retaliated and conquered the tiny nation in 208 NDE.
The popular story says that the invasion of Bralholme only took two shots, both from the now dismantled Joule Cannon. This isn’t quite accurate: the royals of Bralholme did surrender almost immediately, but there were many small skirmishes and fights between rebellous Brallics and the armies of the Great Republic. But still, the story that it only took two shots from the awesome military machinery of the Great Republic to conquer the Brallic people is one every schoolchild in the Republic knows.
