Overview
The Kingdom of Keoland, located between the Javan and Sheldomar Rivers, is the oldest surviving nation in the Flanaess. Since the Twin Cataclysms forced the Great Migrations of prehistory, Keoland has had the most impact upon the history of the Flanaess of any nation outside the Great Kingdom. As the entire Sheldomar Valley has at various times been under the influence of the kingdom, much of this detail has relevance to neighboring states such as the Gran March, Geoff, Sterich, the Yeomanry, and the Ulek States (the County, Duchy, and Principality respectively).
Note: When calculating Common Years prior to the Declaration of Universal Peace in 1 CY, remember that Common Year reckoning has no "year zero." Thus, the time elapsed between 5 CY and -5 CY is only nine years, not ten.
