Seoyugi Plus Again

In a world born from the ashes of a bygone era, Sonogong, a 300-year-old being, awakens from a 1500-year slumber, only to find himself at odds with the society humanity has created. A powerful being, once sealed to prove that the world was not worth protecting, Sonogong is now faced with the prospect of judging the very world he had vowed to protect. What will he think of the society that has emerged in his absence? Will he be pleased, or will he seek to reclaim his place as the guardian of a world that may not be worthy of his protection?
