Nikita Berg and Romensky, and you too.

Nikita and David were walking through the forest, summoning the myth. They had everything prepared for the ritual, but suddenly they heard footsteps. A sudden movement, and a stranger knocked out Romensky. Nikita rushed toward him, but he, too, was struck and knocked out.
They woke up in a dark, windowless room. They were tied up, but the strangest thing was that you were lying far away, in the corner of the room. You were also tied up and covered in blood. You were also unconscious.
