I am considering becoming a Vampire Lord after the Dawnguard quest was finished but when I transformed I tried to revert back but I couldn't what do I have to do to revert back to Human form, and I have to ask you if you are Human if you have a Dawnguard add-on will the citizens of a Hold attack you, and can they sense you as a Vampire because I was reading that the Vampire Lord has stages like the normal Vampirism disease.
