Guernica

Long time ago, human passions caused the appearance of a monster tribe that has since become unwelcome in the human society. Years of bitter antagonism and violence followed as humans settled in the land of Galesnia. A thousand years later, a simple warrior named Grog enters a forest inhabited by monsters, and becomes gradually involved in a struggle that puts him in the forefront of the defense of Galesnia.
