"Night assembles, and now my watch starts. It will not end until my demise. I will take no spouse, hold no terrains, father no youngsters. I will wear no crowns and win no greatness. I will live beyond words my post. I am the sword in the dimness. I am the watcher on the dividers. I am the shield that monitors the domains of men. I promise my life and respect to the Night's Watch, during the current night and every one of the evenings to come." Night's Watch Banner.
―The Night's Watch oath[src]
The Night's Watch is a military request which holds and protects the Wall to keep the wildlings and White Walkers from intersection into the Seven Kingdoms. The request is a sorry excuse for its previous quality and its pitiful powers have been crushed by ongoing assaults from both wildlings and White Walkers. For the recent hundreds of years, the request has been driven from Castle Black.
The Night's Watch is composed in three offices: the Rangers, who battle, guard the Wall and watch the Haunted Forest; the Builders, who keep up the Wall and the palaces; and the Stewards, who backing and feed the individuals from the Watch. Night's Watch Banner.
Following the Breaching of the Wall, Jon Snow required the rest of the individuals from the Night's Watch to come to Winterfell to help shield against the Night King and the military of the dead since the Wall never again serves any cautious purpose. With the annihilation of the White Walkers in the Battle of Winterfell, the Watch's motivation has been satisfied, yet keeps on filling in as an isolate for the expelled, poor and unfortunate.
