for reference a quote from the book:
|“|| The tale of Night's 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 white 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.

TV series spoilers
In the fifth season of the TV series a "leader" of the Others/White Walkers was introduced, descripted as "Night's King"! How should we handle this here? --Exodianecross (talk) 07:55, 6 June 2015 (CDT)
Wasn't he actually introduced in the fourth season? When the walker brought him the baby? Anyway I suppose the thing to do would be to make a TV series section on the page. Similar to what's done here: Marillion--RumHam (talk) 09:35, 6 June 2015 (CDT)
