From gentle herbivore to the most ferocious carnivore, your path will bring you into contact with all kinds of species on Atys. Sooner or later however, you will have to face up with your most dangerous adversary: the kitins. Organized, powerful and devoid of pity, they ravaged Atys in 2481, massacring Fyros, Matis, Trykers and Zoraïs indiscriminately and wiping out their entire civilizations. Homins have since developed new combat techniques that allow them to keep their enemy at bay, but the fight is by no means over. Show no mercy to kitins if you wish to survive.
