Khthon is a world where all species are intelligent--but with intelligence comes conflict. Here, the four Civilizations, the Avians, the Feline, the Canine, and the Equine, who previously lived in peace, are faced with both internal and external conflict. Religious differences between the Felines and Canines cause a constant rivalry between the two, save for the few peace-loving citizens of both who are forward-thinking enough to forget their differences. The Avians find themselves feeling superior to the other races, including those Mythics who live in the Olde Woods. Meanwhile, the Gods become more and more angry at the impending situation, and severe weather patterns start to erupt in the harsh and craggy environment of the Mountains. But worst of all, there is tyranny within the Equine race. Xathiador has recently inherited the throne from his twisted father, after the pure and benevolent blood of the Equine Line fell to the carnivorous and greedy Diomedean Line several hundred years ago. Now, he rules with greed and corruption. But like his father and grandfather, Xathiador fears for the end of his reign. Now, he seeks to solidify it in any means possible--his ultimate goal: to rule all, forever.
