Zosa is the northernmost permanent settlement in Myaasia (with the exception of Askalon far to the east.) The inhabitants consist in equal parts of former inhabitants of Zosa, survivors from Zorim and soldiers other cities. With the Northern Empire a part of history, Zosans consider their town to be a part of the Central Kingdom. They are a hardened lot, many of them veterans of several wars, who have vowed not to let the town fall to unlife a second time.

In the late third era Zosa was a small town occupied by the forces of the Northern Empire. It was a staging point for the frequent wars and skirmishes between the Empire and the Central Kingdom. During the Unlife Wars, the inhabitants fled southwards before the armies of Clagor. After the end of the war, the survivors of Zosa along with any of those few survivors of Zorim and other cities of the north that chose to return, resettled the town, to oppose the unlife still controlling most of the north.
