At last, Quel'Delar is restored for the glory of the Sunreavers and the sin'dorei! All of Silvermoon will proclaim you a hero, as will all of the Horde.
Archmage Aethas Sunreaver, the leader of the Sunreavers, asked to see you after you returned from the Sunwell. Travel to the Violet Citadel in Dalaran as soon as you can, <name> and bring Quel'Delar with you. The archmage wishes to congratulate you personally!
Quel'Delar rises again, as the sin'dorei have risen from the ashes of defeat and betrayal. Yet, somehow, the weapon of Thalorien Dawnseeker has chosen to serve an outsider.
Be at ease, <name>. I do not mean to diminish your accomplishment, for you have done what none of my brothers could, although I do not know why. You are clearly meant to be its bearer; the blade is already adapting itself to your abilities. Wield Quel'Delar proudly against our common foes.
