The Wanderer stands poised over the Waste, carrying within all the memories of what has gone before, weighed down with the knowledge of “how it has been.”
The Waste is a new world filled with dangers and signs that the Wanderer must learn to see and adapt to. The old knowledge is of little use here. The Wanderer must move forward at their own risk.
The White Dog looking back is a reminder that watchfulness and loyalty to those you choose as Pack or Tribe is important for survival. This can be a signal of Big Change.
