N8. CASTLE BLACK- THE WALL
Castle Black features six separate towers, five fortified keeps, a great hall, and a series of tunnels that allow the castle’s grounds to be traversed during the long winters’ 10-foot-high snows all at the center of The Wall, a 700-foot-high block of frozen ice.
Situated in the top of the world, Castle Black is the best place to be if the wildings or the winter are following you. It has stored in its basement food and supplies.
The bad news of all that are the army of ice zombies and their terrifying ice spider pets.
