When the Burning Legion returned to Azeroth, Grand Magistrix Elisande formed an alliance with Gul'dan and allowed the Burning Legion to occupy Suramar City. First Arcanist Thalyssra realized what a mistake this was and led a rebellion to overthrow the Grand Magistrix. The Nightfallen are the nightborne elves that allied themselves with Thalyssra. After defeating Sargeras, thereby ending the threat of the Burning Legion on Azeroth, for the moment at least, the Nightfallen allied themselves with the Horde against their ensuing war with the Alliance.
