The Wights
The wights are the walking dead, corpses reanimated by the cold magic of the Others to serve as their foot soldiers. They are the most immediate and visible threat from beyond the Wall, a tide of undead that can overwhelm the living through sheer numbers and relentless, mindless aggression. Unlike the Others themselves, who are sentient and commanding, wights are puppets, animated by a malevolent will that drives them to kill all living things. Their existence is a violation of the natural order, and their appearance heralds the return of the Long Night.
Nature and Animation
Wights are created when the Others raise the dead, whether human, animal, or giant. The process is not fully understood, but it is tied to the extreme cold and the Others' magic. A corpse that has been touched by their power will rise again, its flesh pale and cold, its eyes glowing with a bright blue light. The wights retain a semblance of their former shape but are utterly devoid of will or memory, driven only by the command of their masters. They feel no pain, fear, or fatigue, making them relentless foes. They can be created from any dead creature, as seen when an Other rode a dead horse, and accounts speak of giant ice spiders as well. The wights are not truly alive; they are animated corpses, and their only purpose is to serve the Others' agenda of extinguishing all warmth and life.
Vulnerabilities and Weaknesses
Wights are notoriously difficult to destroy by conventional means. Ordinary steel blades are largely ineffective, often passing through their rotting flesh without stopping them. They can be hacked apart and still continue to move, as individual limbs may continue to crawl and grasp even after being severed. Fire is their primary weakness; it burns them utterly, reducing them to ash and preventing any further reanimation. Obsidian, or dragonglass, is also effective, as Samwell Tarly discovered when he used an obsidian dagger to kill an Other, and it is implied that the same material can destroy wights. The wights are also slow and clumsy, lacking the speed and coordination of living men, which can be exploited in combat. However, their numbers and tireless nature make them a formidable enemy, especially when they rise from the snow in ambush.
Encounters and Threat
The wights are encountered throughout the narrative, primarily beyond the Wall. They attack the Night's Watch at the Fist of the First Men, where they swarm the hill in a tide of dead flesh. They are also present at Craster's Keep, where they kill the Lord Commander Jeor Mormont. The wights are a constant threat to the free folk, who are fleeing south to escape them. They are described as "dead things in the woods" and "dead things in the water," indicating their pervasive presence in the haunted forest and along the coast. The wights are not just a physical threat but a psychological one, as they represent the ultimate horror of death without peace, a fate worse than simple mortality. The Night's Watch and the free folk must learn to fight them with fire and obsidian, as conventional weapons are all but useless.
Significance and Thematic Role
The wights serve as the primary antagonist force in the series, embodying the existential threat of winter and the Long Night. They are the reason the Wall was built and the reason the Night's Watch exists. Their presence forces the living to set aside their petty squabbles and unite against a common foe. The wights also serve as a symbol of the corruption of nature and the violation of the cycle of life and death. They are a reminder that death is not the end, but a transformation into a state of eternal servitude to a malevolent power. The wights are the ultimate test of the living's courage and resolve, and their defeat is essential for the survival of humanity in Westeros.
