Her name is Doomsayer.
Note: I own nothing but my own character and personalities I give to preexisting characters. The rest belongs to Tui T. Sutherland. Also: I would advise you read up to book 6 in wings of fire series and possibly the wings of fire legends: Darkstalker, for this to make sense and not spoil too much.
