Their quest is to improve their way of life. They fight battles with ferocious beasts, killing them or driving them away from the land they regard as their domain. Guided by Huyuk and his mate Catal, the people search for others, to learn from them and exchange ideas. In a very short time, their little village grows and prospers. Krot, however, is envious of his brother's success, and his cruel nature prevails over him, thus bringing to his people murder and misery.
