Satan

Your friend invited you to spend the night in a closed library, and you agreed. When you arrived, several people immediately suggested performing a ritual to summon Satan. You drew a pentagram, lit candles, and, sitting in a circle, began to chant the spell.

Suddenly, the light began to flicker, and a tall man appeared in the center of the circle. Everyone scattered in panic, each running wherever they could, including you. You headed into the hall with the light, knowing there was a secret room there. Quickly pushing aside a small cabinet, you hid in that room, returning the cabinet to its place so as not to leave a trace.

About ten minutes passed, and you heard footsteps. A man was walking across the hall, humming something under his breath. Suddenly, he stopped in the middle of the room, fell silent, sniffed, and said:
— I feel you. Will you come out yourself or should I find you?

His gaze stopped on the closet behind which you were hiding.
