- "I've seen how the land stretches much farther than any man knows, into the Land of Always Winter where the White Walkers came from during the Long Night."
- ―Jon Snow
The Lands of Always Winter, also called the Land of Always Winter, is a colloquial term referring to the north-most regions of the continent of Westeros. They are so-named as snow falls in these lands even in the warmest summers. The wildlings controlled some of this territory, but it also extends into subarctic wastelands that are inhospitable to human life. These lands are said to lie north of even the Haunted Forest and the Frozen Shore, beyond the Wall. The land was not always so, having once been a lush, forested land inhabited by the Children of the Forest in ancient history which they used to perform rituals and turn a captured human into the first of the White Walkers. Thereafter, the land became an icy tundra, birthplace of the Walkers and their last stronghold to which they retreated after the War for the Dawn.
Bran Stark and the Three-Eyed Raven see the lands north of the Wall in a prehistoric period of time when they were green and inhabited by the Children of the Forest. Bran later sees the lands in the present day in a subsequent vision, where a massive army of wights and the Night King are stationed.
Bran wargs into a flight of ravens that fly over the Wall into the Land of Always Winter. Through the ravens, he sees the Army of the Dead: an army of Wights led by the White Walkers and the Night King, traveling south towards Eastwatch-by-the-Sea.
After the Great War is over and the Night King and his army are destroyed, it is unknown what became of the Land of Always Winter. It is likely that it remained frozen and empty, as there are presumably no known living creatures that could survive there.
In the books
In the A Song of Ice and Fire novels, the Land of Always Winter is mostly unexplored. It lies beyond the northern-most wildling kingdom, the land of the Thenns in the northern valleys of the Frostfangs. The wildlings believe that the White Walkers hail from this icy place, but even the northernmost wildling tribes have little if any knowledge of the region - as few who have ventured so far north have ever lived to tell about it, if only due to the deathly cold temperatures.
