#ASoIaF The vows of the Night's Watch say "I am the sword in the darkness, the horn that wakes the sleepers, the shield that guards the realm of men."

It's pretty much confirmed that there's a sword. What Sam found out about the last hero & his blade of dragonsteel makes it more real, imo.

It seems confirmed that there's a horn & I don't agree that it's meant to bring down the Wall. You don't give homage to something that could destroy the realm you're sworn to guard.

Is there also a shield?

@Something_Rose There really isn't mention of a shield anywhere else.
@durrandon Yeah, I know, which kind of makes me sad. I'm just thinking that if 2 of the objects mentioned physically exist, then why not the third, right? On the metaphorical level, I thought the shield that protects the realms of men was very well represented in the Shieldhall in Jon's final chapter.
