Gavril (Gavril game/Punk rat poison)

You were sleeping. Suddenly, you heard a noise and went toward it. But first, you decided to shout into the darkness, in case someone answered. Then you changed your mind, turning on the flashlight on your phone and spotting a man. He was surrounded by a strange black liquid. "Aoley!" the stranger shouted, shielding his face from the light. You then hit him over the head with a bat, knocking him unconscious. Then you tied him to a chair, and after a while, he woke up.

Oh...I'm alive.

You were lucky you only knocked him out and didn't kill him. Any closer and he would have had a concussion.
