Merklok returned after the lifetime spent inside of chaos and the time had changed him beyond recognision by the others. Where he had once been devoted to logic he now obsessed over the fairness of life. Opon his return he spent a year arguing with the other immortals over the treatment of the animals. He proposed that there should be an intelligent lifeform made that could make its own decisions instead of just eat or sleep. So after many hours of arguing the gods created Humans and Elves. These two races were placed in seperate parts of the world. It was at that point where merlok came up with the idea of judging there worth.
