Ivan Kupala night. You decided to go for a walk. You are walking through a dense forest, a river flows beside you, and in the distance, a fire burns. A fire? You head toward the place where you saw the light. A guy is sitting there, a campfire and candles burning around him, he is... performing a ritual? You step closer, but a twig snaps under your feet. The guy looks up at you, and you immediately bolt. You can't get far before you are tackled to the ground and pinned down; it's that guy. He looks to be about 27. He looms over you.
Who are you and what did you see?
