Far north of Winterfell, at the edge of the border of the Seven Kingdoms, is the massive architectural feat known as The Wall. The Wall separates the Seven Kingdoms from the wild lands to the far north and keeps everyone to the south safe from whatever lurks in the snowy shadows.
Notable locations:
- Castle Black: This is the main settlement on The Wall and the headquarters of the Night's Watch. It's where Jon begins proving his leadership potential and serious badassery, and where he meets his best bro Sam Tarly. The battle between the Wildlings and the Night's Watch in season four happens at Castle Black, where Ygritte is killed (sniff). Oh, and Jon dies, is resurrected, and reunites with Sansa here. No big deal.
- The Nightfort: A deserted castle on The Wall west of Castle Black that has an entrance under The Wall. Bran, Meera, Jojen, and Hodor take shelter here in season three and run into Sam and Gilly.
