With the help of Captain Alpert and his men (at least one of whom is a woman), you INVADE THE DEADMINES! Eventually, you are assisted by Thoralius the orc detector, and he helps with your INVASION!, even though there aren't any orcs. You reach the juggernaught at the back of the Deadmines and defeat the murloc cook who lords it over the place, getting phat lewtz and bringing glory to the Alliance.
Sweet.
