Upon passing his her or initiation a potential brother or sister of the Guild must swear the following oath at the Bones and Feathers Inn in front of the current Prior Brother and all other able brothers currently located on the guild grounds:
Evil gathers, and now my service commences. Such service shall not end until my death or until I am relieved. I shall never attempt to defeat those who cannot be defeated. I shall not ever follow in the steps of the cursed one. I shall wear no crowns and win no glory for myself. I shall live and die at my post. I am the light in the darkness and shall honor the charter for all time. I am the hero this world needs. I am the fire that burns against the cold, the light that brings the dawn, the horn that wakes the sleepers, the shield that guards the realms against all evil. I pledge my life and honor to the Undefeated, for if I shall ever fall, then from this moment on I know I shall remain just so: undefeated. Until the gods themselves eat up this world for all time. Until time itself reaches its end, Undefeated shall I ever be.
*Totally plagiarized that from the Martin books. I copy and pasted the oath the Night’s Watch members have to take, edited it a bit, and there you go. —JMK
