Representing the furthest point of encroachment by the ancient Tevinter Imperium into the barbarian lands of the southeast, the fortress of Ostagar was once one of the most important defensive holdings south of the Waking Sea. It stood at the edge of the Korcari Wilds watching for any signs of invasion by the barbarians known today as the Chasind wilders. Straddling a narrow pass in the hills, the fortress needed to be by-passed to reach the fertile lowlands to the north and proved to be exceedingly difficult for the wilders to attack because of its naturally defensible position.
