The Capitol Coup happened sometime in 507 ANI, when an unknown group of Luminals assassinated Dread Emperor Karsen. Imperial Princess Nima was unable to take her father's throne and Civil War erupted between rival factions among the Luminals.
The Civil WarEdit
Many of the Luminals mustered their local orcs into Legions and moved the capitol to fight for the throne. At least some of the Luminals in Zerniless, Menkgu, and Gandabria stayed behind to continue the war against the Dwarfen Safeholds.
