Prophecies sometimes turn out true. [Though he's not been hearing much of the Prince That Was Promised prophecy, not since Melisandre was sent away. His mind had been too focused on the reality, the absolute fact that this war was coming and it was largely possible they would lose.] People don't tell stories about the monsters of your world?

[He couldn't help but smirk, well aware of how this sounded. He dismissed it too, until he was forced to confront it at the Wall. He had to wonder if it was a relief to face simple monsters, not something like...whatever the Others were. They weren't snarks or grumperkins, but more dangerous. Like death walking.]

They're the final battle between life and death. [Again, an insane notion, but one that he knows is true and won't be shaken from that.] I saw their full force at Hardhome, a Freefolk village. Thousands of dead threw themselves from a cliff and got to their feet and charged at the men, women and children. Those killed were raised effortlessly, doubling the Night King's army. Nothing could stop them, nothing slowed them. They are death and bring death.
