You must find the blue dragonflight drake champion, Scryer, and slay him. Pry his skull from his corpse and return it to Emberstrife. You know that Scryer can be found in Winterspring.
We are Deathwing's children, whelp. Our dominance over the lesser Aspects must be enforced.
If you are truly worthy of ascension, the lesser dragonflight will wilt in your presence.
Find their champions and lay waste to them in the name of our Father!
Travel to Winterspring and track down the mighty blue drake, Scryer. Crush him and any of the Blue Flight that stand in your path. Tear out his skull and return it to me.
