Rise of the Shadar-kai
Mosasa. Not much is known about this aloof Dragonborn. Observed from the point of his blade or at the forefront of a Mercenary Army. What people do know is that he is a deadly swordsman, skilled with the Longsword, far surpassing any known mortal. Some attribute it to his wanderings, his insatiable desire for knowledge and technique. Or the rumors say. Others say he is a Demon, and must be exorcised from these lands. A Lone Swordsman for hire or a Demon. Either way, whoever pays the most handsomely, acquires a fearsome ally in their campaigns.
