2/3 times ive done this quest, i've gotten attacked by a dragon. The first time it happened upon arriving at the quest location, so I just ran inside. The second was right before taking the carriage (you have to take one). All I had was a glass dagger, sanguine rose, and a bow. Twas probably the most epic dragon fight i've had-ive got max magic resistance, but the dragon bite 1-2 shot me on master.
Anyone else have stories of dragon fights at the worst times, like during this quest?
