Population Migration / Travel
The massive pilgrimages/dislocation of the people that changed the country immediately following the signing of the peace treaty. This divided history into Before Fracture and After Fracture. Year 0 being when the peace treaty was signed, permitting travel to desired locations with no fear of violence or restriction. This reunited families and gave power to the people to choose how they wished to live. The original Citadel in the center of the country was left in ruins from the crusades and abandoned to find a new place to call home, leading to the three major cities being rapidly urbanized (Steadfast Hold, Thornmere, and Harvestall).
