During the Age of Might there was active trade & travel between Arcadia, Bravo and Caldonia. Towards the end of the Age of Might Human settlers travelled to Caldonia and set up colonies there.
At the end of the Age of Might occurred the Breaking of Arcadia. Arcadia had deep river canyons form, land sink into the sea, and had a desert form. Bravo's become a mountain covered jungle. Caldonian was frozen over. Because of this event the people of Solum consider Arcadia cursed by the gods.
