The White Walkers, or Others, are a tall race of humanoid creatures with glowing blue eyes, enormous strength, and the ability to freeze anything into solid ice. They are led by the Night King, a once-human man who was turned into the first White Walker by the Children of the Forest.
White Walkers reside in the frozen lands north of the Wall and have not been seen in the Seven Kingdoms for over 8,000 years. As a result, they are considered extinct, although a few people, like Jon Snow and Samwell Tarly, know otherwise. It is thought that they will invade the Seven Kingdoms when the Long Night falls.
White Walkers are only vulnerable to fire, dragonglass, and Valyrian Steel, and can create armies of undead wights to do their bidding.
