Wanted: The Signet Ring of Prince Kael'thas

<class>, today I ask the impossible. Today, you must obtain the signet ring of Kael'thas Sunstrider, lord of the blood elves! It's true, the rumors of his death within Tempest Keep were ill-founded. He has appeared once more, this time at the Magisters' Terrace on the Isle of Quel'Danas. What he is doing there is a tale for someone else to tell you. What I know is that I have innumerable collectors interested in his princely ring, and I mean to acquire it for them. Or rather, I mean for you to do so.
