Chapter 414: The highest degree of heresy.
Noble Vampires.
Unlike Vampire Slaves who, in the literal sense of the words, were dead,
Vampires Nobles are different.
They are alive, they can reproduce, and they are essentially immortal as long as they aren't destroyed by targeting any of their weaknesses.
These being the destruction of the heart and the head, Hunter's magic, fire, and sunlight.
Another of their most notable weaknesses would be that they cannot enter a person's 'domicile' unless invited, a weakness that is easily resolved by destroying the house.
Or they feel emotions more intensely than all beings.
If they love something or someone, they will love it/them very much.
If they feel they have been betrayed, the hatred for that betrayal will be felt much more strongly than usual.
They are quite problematic because of this nature of theirs.
