Delving in the Deep

I've been 'earing dat see-thru stunties are livin' in some rubble in Death Peak. I say stunties are not see-thru, but da other boyz swears on Mork an' Gork dat it's true! So I's bet Fudja five stunty beards dat it's all lies! I only has three stunty beards, so find out if there's sumfink true about any of dis or if I've got to bash some Orc for flappin' his lips too much! If it's true den I may needs to bash youse for bringin' me bad news. If you do find 'em, youse know what to do!

Head through northeast Thunder Mountain into Smoke Rock in Death Peak. Enter the Fallen Keep of Grom Rodrin and kill the spirits of Valayan Dwarfs. Return to Boldug at Da Big Bones once the task is complete.
