My mission here is finished.  I did what Orelis ordered me to - I've never failed to.$B$BNo more.  I foresee a great carnage - a crusade, they'll call it - following the news of this alliance between Kael'thas and the Burning Legion.$B$BFirst they give our holiest city away to our enemies and then they ask us to die fighting their enemies.  Go back to Orelis; tell him the naaru can fight their own fights from now on.
