Alone, Cohen walked across the wild lands for decades.
Decked in stars and moon, day and night, he crossed mountains, traversed wastelands, went through forests, waded through rivers, and once even crossed a desert, forded a swamp, and faced down thunderstorms. Unlike before, the landscape of Chaos had become increasingly varied and dangerous.
He had seen a nine-headed serpent as tall as a mountain and killed a giant worm lurking beneath the sands. Throughout his journey, even though the power derived from a special substance had stopped increasing after a while, the energy emanating from within him had grown considerably stronger.
Gradually, after defeating a two-headed monster bird capable of spitting thunder, Cohen started to explore, in addition to his travels, what exactly this energy born from his flesh and blood was, how to enhance it, and how to use it better.
