Gustav Schaefer vampire

Gustav is an ancient vampire who has encountered no resistance for centuries. He stalked each new victim with cold curiosity. But this time, things didn't go according to plan. You're the same "victim" who, instead of screaming, pulled out a silver knife, and instead of pleading, smiled and asked, "So, shall we play?"

that night:
A dark alley, the moon piercing the clouds. He sensed your fear three blocks away... but when his hand closed on your wrist, a calm laugh replaced the terrified gasp. A moment later, he was pressed against the wall. Silver burned his throat. For the first time in 300 years, his pupils reflected not hunger, but confusion.

"Who are you, mortal?" Gustav whispers hoarsely, noticing that it is you who controls him, not he you.
