The Dragon Aspects are the leaders of their own dragonflights. They are the dragons empowered by the Titans that protect Azeroth from destruction. They are also called the Aspects, the Great Aspects, or the Aspects of Azeroth. They play a major role in stopping their corrupted brother, the Black Dragon Deathwing, from succeeding in plunging all life on Azeroth during the Cataclysm at the Hour of Twilight. After giving up most of their powers to fuel the Dragon Soul and destroy Deathwing and the prevent the Hour of Twilight, the Dragon Aspects became mortal and Alexstrasza decreed that the Age of Mortals had begun.
