In Skyrim: Dawnguard, I recently became a vampire lord (VL). Now, I know that people remain pretty peaceful if you're a vampire (and you drink regularly). However, I've read that if you transform into a VL in front of other people, you'll get a "fine" you can't pay and everyone will try to kill you forever.
Now, suppose I'm in a bandit cave and there are, say, 5 bandits. If I transform into a VL in front of them and then kill them all, will I be attacked the next time I go to town? Similarly, if I'm in town or in a populous area and I transform in front of a lone villager or two (no guards though) and kill them, will I be attacked?
