Era of Upheaval
Sahuagin are the natural enemies of the Hu empire and the Orca Dragonborn Pride. Sahuagin could not co-exist peacefully, and wars between them were often prolonged, bloody affairs that occasionally even interfered with shipping and trade. Sahuagin tolerated the Dragonborn much more than they did the Hu. The Sahaugin terrorized the Southern and Eastern Seas of Darastra, even venturing as far as the maelstrom
Multiple births were frequent among sahuagin, and they dealt very harshly with offspring who were not robust or aggressive enough, eliminating them through compulsory fighting to the death between young sahuagin. Sahuagin seemed fixated on all aspects of consumption, and were eager to weed out anything they saw as weak or unworthy to compete for resources.
