Niuso (pronounced nigh-OO-so) of the Salonius dynasty was the king of Viridia from Y9422* until he was deposed in Y9425*. Niuso took the throne in the midst of continued upheaval in Viridia, as the senatorial nobility of the Dominion continued to reckon with the loss of territory conquered by his grandfather, King Avus IV.
Unlike his mother, Queen Vita, Niuso lacked the diplomatic skills to keep the senate in check. After a brief reign marked by an inability to pursue his own efforts, in Y9425* Niuso was given an ultimatum by a group of almost thirty senatorial families - step down, or face a civil war. Rather than tear the realm apart further, Niuso agreed and quietly retired to his estate outside Alatra. Though the family remained entitled to a membership in the senate, Niuso did not take part himself as is traditional for the head of house, but instead left the role to his niece.
Today, Niuso is mostly remembered as an ineffective leader who lacked the skills or charisma necessary to maintain the his rule over the Dominion in a trying time. Though widely disliked during his life, contemporary views have softened, and he is now primarily viewed as someone forced into a situation in which they could not win.
