Go with Brann and Khadgar to Ulduar and hear Magni Bronzebeard's message.
Me brother Magni, once King o' Ironforge, got changed into a diamond statue by a titan ritual. He's stood frozen in the belly o' the city fer years.
But I just got word that he's up and around... sayin' he knows somethin' 'bout how to beat the Legion!
Look, <name>, I dunno if Magni's crazy, or if that's even really him. But if there's even a chance he kin help us...
I'm told he muttered the name Ulduar. That's where I'm headed! I'd be obliged if you an' Khadgar were ta join me.
