Castanor is the general term used to refer to the various stages of Castan's Empire.
Historical Castanors
Early Castan's Empire (639 BA - 471 BA)
The early days of the Empire was the evolution from a series of tribal kingdom confederations, led by Castanor, into the establishment of law and order under a more centralized empire as well as the continual fight between man and the wilds.
Greater Castan's Empire (471 BA - 1 AA)
The golden age of Castanor was under Castan the Great. This period saw great expansion of Castanor into the rest of Cannor, as well as the Wars of Dominion against the other two powers of antiquity.
Late Castan's Empire (1 AA - 1021 AA)
The gradual weakening of Castanor started with the Day of Ashen Skies. This is a period of strife and conflict and for a long time Castanor was no longer a united polity but fought for by powerful lords and pretenders. At the later stages all of Castanor was unified again by the foreign reaver Castan Ebonfrost, until its dissolution in the War of the Sorcerer-King.
Chivalric Escann (1021 AA - 1424 AA)
After the War of the Sorcerer-King the Trialmount which determined who would bear the title of Castan was cursed and inaccessible, leaving Escann without any clear leaderships. Escann collapsed into a land of petty kingdoms, with the largest at the time being the Kingdom of Cast and Kingdom of Anor. Eventually the two kingdoms merged into the Kingdom of Castellyr, and the kingdom remained the dominant force in the region along side other kingdoms like Adenica and the Blademarches.
Chivalric Escann is noted for the custom of the Trial of Chivalry, which allowed disputes, even wars, to be won over by a trial-of-combat or other relevant chivalric affairs, such as jousting. This spared Escann from many deadly wars, and for a time, the region flourished. Most historians agree that this weakness and ill-preparation for war was one of main factors in the success of the Greentide of 1424, which saw the land destroyed.
