Is that—yes, I think it is! There's a Dwarven power core in that chamber! I should march right in there and grab it. Raynor will be so pleased. I can't wait to see his face when I hand this to him.

Not only is that chamber crawling with Dwarven constructs, but there's a mean-looking centurion called a Ztheng Guardian standing near the power core. I'm going to look around some more and see if I can come up with a way to sneak off with that power core.
