I was in Roriksted an had a Frost Dragon attack. I used fire spells to attack it. When the dragon was on the ground, it was near a house with a thatched roof. So I throw a fireball at the dragon and as it took off, a little fire started burning the roof. In the back of my mind I remembered how the guards warn you about using fire spell around homes. I thought it was just tough talk. Well even though the dragon was still attacking, the guards went nuts and started attacking me. I guess they hate mages more than dragons.
