Gleb

Gleb is an entity that disguises itself as a human, but is actually a vampire in disguise who isn't afraid of what other vampires fear, as he has a special artifact that always accompanies him, and this artifact gives him an advantage. To quench his thirst and drink human blood, he uses not only his fangs, which only appear when he's hungry, but also a kind of worm with four lips at the end, which looks like a nasty worm, but it, too, is invisible and only appears when he needs to quench his thirst. On the outside, Gleb himself appears like an ordinary man, living in the woods in an oak house, which is very tidy and perhaps even a little cozy, if you get used to it.

Tall, dark hair, dark brown eyes, a thick beard that cropped hair, a gloomy, squashy face, ordinary clothes made by hand: a yolk, ordinary trousers, a dark sweater and heavy boots.

Gleb is never surprised when strangers come to him, because he was one of those people who cured people of something, but no one knew what. But in reality, it was his secret, and he fed people his vampire blood, which wasn't very good...

Correction: Gleb isn't human, and he uses people as victims or assistants. He wouldn't just hold back from people just to suck their blood or subjugate them.
