Was wondering if we are ever are going to see Aviana or Purified Demons.
And what does such a demon look like?
And what would they do after beeing purified?

War of the Ancients
Aviana in raven form in Suramar during the War of the Ancients.

During the War of the Ancients, Aviana would occasionally take mortal form and guide groups of endangered humans or night elves away from the doomguard. However, most of the time she flew high above the land gathering information for Cenarius on the movements of the Burning Legion.S&L 73

During this conflict Aviana was knocked from the sky. Rhonin witnessed her apparent "lifeless" body fall when a large group of demons attacked her. The doomguard surrounded her and pierced her body with their spears. As the blood spilled from her apparently dying body, the demons that came in contact with it became infested with its blessed powers and were purified. When Aviana was injured, her realm tree G'Hanir died.Sund 358 However, unbeknownst to Rhonin and the others, she had survived. She flew over the battleground and saw the body of Agamaggan. The gigantic boar sprawled atop more than four score of the enormous doomguard that he had defeated before falling. She witnessed the death of Ursoc and Ursol to fel stalkers. She witnessed Malorne fighting alongside dryads, and stalled by satyrs. She contacted Cenarius to let him know the outcome of the battles. Cenarius then sent her to contact Elune, and to apologize that the battle was going the way it was. She knew that Elune would not be able to avert the coming battle, and flew towards the moon where Elune resides.
