There is no way to escape the doing of our world, so what a warrior does is to turn his world into his hunting ground. As a hunter, a warrior knows that the world is made to be used. So he uses every bit of it. A warrior is like a pirate that has no qualms in taking and using anything he wants, except that a warrior doesn't mind or he doesn't feel insulted when he is used and taken himself
