Nexus is one of seven cities established by some Archmages which led the 7th Legion of Veil. Some time after the Lord of Ruin's forces were defeated, Ataraxis founded Nexus, which lies near a convergence of magical leylines. For a time, Ataraxis ruled Nexus and it's human inhabitants, but he eventually passed his rule of the city to capable mortals. The Kings of Nexus are elected by considering their political acumen, sorcery talents, and social benevolence. Therefore, a new king can only be elected when; upon death of the current king or retirement, and the worthiness of the new candidates or inadequacies of the current king.
