What do the White Walkers in Game of Thrones have against the southerners or even the living that they are hell bent on killing them all? What exactly is their purpose? All they want is to conquer south of the wall, is that it? Also, is there any possibility that the leaders of the Walkers are dead important figures from the past, like Rhaegar or Rickard even?
