Sularia

Sularia is an extensive, mostly hilly and mountainous region in far southern Orithea. Together with Vastemar to its west, it forms a huge belt of rugged, elevated terrain running all the way across the continent’s southern edge from sea to sea. Major geographical features of Sularia include the Aghai Massif, the Zanobian Mountains, the XXXXXX, the XXXXXX, and the XXXXXX. It’s southernmost margin, where the rugged highlands give way to vast subtropical savannah, is typically understood to form part of the dividing line between Orithea and Ulthark. To the east, Sularia slopes down to a mostly narrow coastal plain on the shore of the Emerald Ocean. In the west, its own mountain ranges join those of Vastemar; there is little clear geographical divide between the two regions, and the distinction between them is mostly cultural and historical. Along its northern edge lie the Dranurian highlands (also mostly contiguous with Sularian ranges), the Sornele, and the Jade River basin.
As in Vastemar, the human and dwarven kingdoms of Sularia had formed Orithea’s buffer against the menace of orcdom since ancient days; and as in Vastemar, they were finally overrun and destroyed by Gol Garga’s terrible horde. Those of their inhabitants who weren’t slaughtered outright fled north and east as refugees, or fell into orcish hands as slaves. The former Sularian bulwark states included Chaleban, Thorondul, Kuzul-Khabrak, Batur, Darzalik, and Zanbalik. All are now gone. 
The so-called Free Margraves of the Aghai are the last unconquered remnant of Zanbalik (and thus the only remnant of human civilization in Sularia), now reduced to collection of independent statelets since the dynasty to whom their lords swore allegiance has been snuffed out.
