You run to the nearest open door and slam it shut. After 3 pounds from the other side, there is silence. You keep the door locked and observe the room. There is a black canvas with tiny etches hanging on the wall.

「 The Winding Maze (c. xx45) 」
「 After reaching the end, the ??? got the ??? a loud snap and a shriek was heard.」

You don't know some of these words.
Hint:

Completing the maze reveals a second art piece.
