First Cironean Civil War

The First Cironean Civil War, also called the Left-Right War, is the bloodiest civil conflict in united Cironean history, and by far the bloodiest war in Beluan history, with almost 3 billion deaths.

The war's end led to the start of the 3rd Era and the creation of the Cironean Commonwealth. It also led to the current bitter hatred of leftist ideals in all Cironeans (Yes, literally, ALL of them).
