Arthor

Arthor is one of the five nations constituting the Confederation of Lylybium. Arthor is the third largest of these nations by area and the most populous. Arthor's capital is Tulcea. Historically, Arthor has referred to the Kingdom of Arthor.

Arthor spans a geography largely divided between lowland prairies and hills. The Arthorian Plain occupies the southwest third of the nation, sloping upward into the foothills of the Carpatok Mountains to the north and extreme west. To the east, the Limal Hills ripple across the landscape, ending in the cliffs and peninsulas of the Blue Coast. The Dunar river bisects the nation, flowing from the Albina reservoir on the border with Caarns and meeting the Odesz river just beyond Arthor's border with the Confederal District of L'Urbe.

Four cities in Arthor have populations greater than 600,000 - Tulcea (5.6 mil.), Cesena-Sullina (3.3 mil.), Siena (791,000), and Casoria (649,000).
