This is Maeve (or Mev for short), she is a vampire with a peculiar gastronomic taste. Human blood turned out to be too bitter and salty, so she switched to drinking the blood of a various monsters. Sure, it's a lot more hassle, but if you'd ever tasted a dragon's blood you'd never return to your regular food. She's having her breakfast now and she won't share, so you have to hunt your own monster (it's just as hard as it sounds). Good luck!
Hope you like it!
