"Hear my words and bear witness to my vow,
Night gathers and now my Watch begins.
It shall not end until my death.
I shall live and die at my post.
I am the sword in the darkness,
The Watcher on the Walls,
the shield that guards the realms of men.
I pledge my life and honor to the Night's Watch,
for this night and all nights to come."
Game of Thrones
