These Look Familiar...

So what is the Iron Horde doing with Dark Iron technology? I know who ta ask! Thaelin Darkanvil is a genius engineer from the Dark Iron clan who's been helping us here on Draenor. You may have already met him in yer travels, eh? Word is he set up a bunker somewhere in Gorgrond, a secret workshop so-to-speak. If ye can find him, he may know somethin' about this. Er, and be cautious, eh? The Dark Iron may be our allies now, but I trust 'em about as far as I can throw 'em.
