Finding a Witness

You have rescued two of our allies from Torghast, but Anduin and Thrall have yet to be found. That tower's corridors are vast... seemingly endless. You could spend an eternity wandering those unholy halls. In your expeditions, you have encountered many unfortunate prisoners. Perhaps one of them has seen or heard something that could guide our search. Seek out any captives that might have the information we need, ‹name›.
