Cairan Heartland
The Cairan Heartland, also Cerulea, is a region broadly south and west of Lake Carles in the western Sabamic Plain; today this is mostly part of Brex-Sarre, Emilia, and Saint-Calvin, but also includes smaller parts of Savam and Argevau. It is known as the birthplace of Cairony, which emerged there in the late seventh century BCE in the holy city and sanctuary of Etamps-La-Sainte; this was the first region where Cairony became the dominant religion before it spread to other areas, notably to the east in Dordanie.
The Cairan Heartland is a subset of the Old Sabāmanian Country, itself the area from which originated the Sabāmani civilisation; the latter term joins the Heartland with the Verbian Country and the Gastes. The region is rich in historical and religious sites spanning three millennia of Sabamic culture, which has supported a flourishing tourism industry in recent decades.
