"It turns out that this pony was a commander in the army of the Storm King, whoever that is, and her distraction while we stole the mirror was to attack the city with her forces and ransack it. I wasn't very happy about that, but I felt I had no choice as we needed that mirror. She promised nopony would be killed if possible, and to her credit, almost nopony was. Instead... they were taken as slaves. I didn't learn that until after though."
