The Sublunary Abyss territory grows and shrinks depending on how large the pack is. They will take up more territory when the alphas feel the need for more space, or during winter when the herds travel the wolves will travel with them. However, most of the time it is limited to eight or so territories. Each one is unique and different in its own way.
View the map below for a quick overview of the territories. For more information on each one, view the forum description and accompanying image.
