Era beginning/end
For roughly 800 years during the “recovery age” The Empire’s leaders were efficient bureaucrats and not much more was required. It was widely understood that the Kingdom of Geldheim was also in a period of growth, as it were, so there were no immediate threats. The only “incidents” of historical note were an uncharacteristic rebellion in 723 AE that was brief, if not brutal, and the worker’s revolt of 1057 AE. Both incidents were fairly speedily resolved with no long term harm done to the progress of the Empire.
