“Another Alliance recruit, eh? I'm Marshal McBride, commander of this garrison. We don't see many of your kind here, hero, but we could sure use the help.
You've arrived just in time. The Blackrock orcs have managed to sneak into Northshire through a break in the mountain. My soldiers are doing the best that they can to push them back, but I fear they will be overwhelmed soon.
Head northwest into the forest and kill the attacking Blackrock worgs! Help my soldiers!”
