The Kinslaying of Dêleondë, the closest the city got to ever being conquered.
The Unification Wars of Fedeledland (also called the Birth Wars, the Dêleondë Conquers or the Dêleondë-Neurialad Wars) were a series of wars raging from the year 9,999 BCE to the year 800 BCE, although most fighting was based in the second half of the war. They were fought between the millenary kingdoms of Dêleondë and Neurialad, their respective vassals Elmar and Relam. It ended as a clear victory for the Dêleondë Kingdom, as Neurialad, Elmar and Relam were annexed into the Dêleondë-dominated Empire of Fedeledland.
