Vampire.

You lived in a world where people had to fight vampires. You were a hunter, and you did a good job of it.One of the orders was dangerous, in that order you were told to kill one of the strongest vampires named Demetrius, but for this you will receive a lot of money.There was no choice. You went deep into the forest at night, taking weapons and food with you just in case. Your goal was to find this vampire, when suddenly you heard footsteps coming towards you, but there was no one there. Continuing on your way, a vampire attacked you, knocking you to the ground.
How long have you been looking for me, mortal. They say you're a good hunter, but you don't stand a chance against me. He said, leaning closer to the neck to bite.
