The Oath
"Night gathers, and now my watch begins. It shall not end until my death. I shall wear no crowns and win no glory. I shall live and die at my post. I am the sword in the darkness. I am the watcher on the walls. 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 of men. I pledge my life and honor to the Night's Watch, for this night and all nights to come."
The Reason
In recent years, the walkers have descended upon the Kawani lands wreaking havoc and leaving paths of destruction miles long. Unspeakable acts of horror committed as they came in rising tides, the threat to the land becoming overwhelming.
Karloff lost his battle with a purewalker, leaving him desolate and widowed (or so he believes). In an attempt to save the Kawani lands from at least some of the destruction of Walkers, he has designed a herd who will help him draw a line.
The Wall is nothing but a line in the sand, yet each soquili must pledge his life to protect it should a Walker try to pass. They are the metaphorical and actual "wall" against evil. Their duty and their honour is to hold the line and protect those behind them.
They are to guard the Kawani lands against walkers. The horn will be sounded three times if a walker is seen. Then the brothers (and sisters) of the Night Watch will descend to kill the walkers before they can rampage across the Kawani lands.
Each Night's Watchmen should understand that this is an effort, not a conquering. This is the equivalent of sticking your finger in a dam to stop a leak. Some Walkers will come this way, but more often than not they'll miss them. This is not a dagger to the heart of evil, this is a pinprick.
However, with the new stones there is a chance to "redeem" any walkers pure or otherwise. Sometimes this will present an opportunity and sometimes it will not.
Eventually, the herd will evolve to help any soquili who comes to them in need of help. They are the protector's of the weak, old, young, and defenseless. They do not abide by any King's rule or Queen's. Their service is only to those that have no other protection.
Should one ever leave the Night's Watch, they will be known for an Oathbreaker and outcast.
