The Central Kingdoms were an unofficial union between the six kingdoms founded by the crusaders Freya, Baldur, Hod, Sigurd, Skadi, and Andvari. They were founded in Y498, following the crusaders’ victory over the Du’un Empire. The kingdoms were plagued by Du’un remnant forces that struggled to rebuild the Empire.
The Remnant War was a large-scale conflict launched by the allied Central Kingdoms to wipe out the Du’un threat once and for all. At the height of the conflict, Freya proposed that the kingdoms be united under one banner to ensure a lasting peace on Norn. The horrors of the Imperial Age and the ongoing Remnant War were fresh in the minds of the Kingdoms’ peasants and politicians and the decision to unify was all but unanimous. In Y506, the Central Kingdoms were rearranged into the Kingdom of Grandévere.
