man, that was a wild cliffhanger for just the first part - really well polished too. It did admittedly feel a little rushed plot-wise - but since that's kind of necessary to establish everything that's hardly an issue.
It is also interesting to guess the powerscaling. Even lesser vampires are clearly quite a bit stronger than humans, and even all sealed up the MC beats them handily. It's unclear how strong Purebloods are other than "current MC doesn't stand a chance".
