The Primordial Age was the era when the Demonic Clan ruled the world, and the Humans were weak. Since the First Emperor, the Humans have been slowly growing through constant work and effort.
During the rise of the Humans, generations of leaders and masters have put themselves on the frontlines of the effort selflessly. From the first of the Emperors of Man, the First Emperor, to the last Emperor of Man of the Primordial Age, Emperor Tai, every single generation of the Emperors of Man have fallen to the Demons. However, there was no lack of great masters deserving of a place in the history books amongst them.
