The Nights king;
He had been the thirteenth man to lead the Night's Watch, she said; a warrior who knew no fear. "And that was the fault in him," she would add, "for all men must know fear." A woman was his downfall; a woman glimpsed from atop the Wall, with skin as the moon and eyes like blue stars. Fearing nothing, he chased her and caught her and loved her, though her skin was cold as ice, and when he gave his seed to her he gave his soul as well.

He brought her back to the Nightfort and proclaimed her a queen and himself her king, and with strange sorceries he bound his Sworn Brothers to his will. For thirteen years they had ruled, Night's King and his corpse queen, till finally the Stark of Winterfell and Joramun of the wildlings had joined to free the Watch from bondage. After his fall, when it was found he had been sacrificing to the Others, all records of Night's King had been destroyed, his very name forbidden.

"Some say he was a Bolton," Old Nan would always end. "Some say a Magnar out of Skagos, some say Umber, Flint, or Norrey. Some would have you think he was a Woodfoot, from them who ruled Bear Island before the ironmen came. He never was. He was a Stark, the brother of the man who brought him down." She always pinched Bran on the nose then, he would never forget it. "He was a Stark of Winterfell, and who can say? Mayhaps his name was Brandon. Mayhaps he slept in this very bed in this very room."
