Thrall finds Alexstrasza in an even more shattered state. He shares with her the vision he was granted, and in solemn silence, the two witness Krasus' heroic sacrifice to protect the Wyrmrests' unhatched children from being born as chromatic beasts. Reinvigorated and regaining her confidence, the Life-Binder travels to the Nexus to join forces with the new Aspect of Magic. Before long, the red, blue, and green dragonflights are reunited with their respective Aspects. With their might combined, they leave to do battle with the murderous Chromatus and his ilk. After a vicious battle, Chromatus reaches his full potential - and overpowers all three of the mighty Aspects. The downhill fight is relieved by the arrival of Nozdormu and his bronze flight, and the Aspect of Time puts forward the notion that they will need to work together, in the most fundamental sense of the word, to defeat this creature that embodies all of their traits and powers. However, Chromatus has a head for each dragonflight, and there are no black dragons present to assist in this task - though Thrall, as a shaman, offers to take on that role. In their humanoid forms, the aspects open themselves along with Thrall to truly gain a sense of unity; and while he struggles to hold the ceremony together, Thrall succeeds in his role in Neltharion‘s stead. Knowing that he could never become as Aspect, he remains content with the notion that he could assist his allies in their hour of need.
The four Aspects launch a volley of powerful abilities at the stunned Chromatus, who cannot bring himself to counter the volatile new powers at their disposal. The chromatic dragon is blasted downwards; the Twilight Father in tow. Chromatus' lifeless body is stored in a specifically-made arcane prison by the blue dragonflight, as it seems impossible to completely eradicate him.
