Clayvale Rebellion

The Clayvale Rebellion was a prolonged period of open warfare between the Coalition of Ordered Governments and the secessionist city-state of Clayvale and, later, the breakaway Confederation of Ordered Governments. What began as a conflict over the sudden secession of Clayvale from the COG over the increasingly authoritarian policies of First Ministers Dyer and Jinn soon escalated into a full-blown civil war between those settlements loyal to the COG and those aligned with Clayvale and its leaders, most prominently, Generals Donald Berkeley and Colin Davis. The war, the largest on Sera since the end of the Locust War nearly two decades previously, and the largest instance of warring nations since the end of the Pendulum Wars, lasted nearly four years before simmering into a series of violent border skirmishes between the two powers. Though the war did not technically end until the signing of the Treaty of New Illima in 42 A.E., it is generally considered to have ended following the Battle of St Diacre, where the Coalition Army was soundly defeated and the current borders mostly solidified around.
