  INT. DIMLY LIT LIBRARY - NIGHT
  
  The camera pans slowly across the expansive library, revealing rows of towering bookshelves that recede into shadow. In the foreground, a flickering candle casts long shadows on a table cluttered with ancient tomes and parchment. The camera moves into DEEP FOCUS, capturing every detail from the foreground to the distant shelves.
  
  At the table sits ETHAN (30s), a weary scholar, frantically sifting through pages. In the background, a FIGURE stands silhouetted, face obscured by darkness.
  
  ETHAN
  (voice trembling)
  I know you're here. I need answers.
  
  The FIGURE steps forward, revealing a mysterious cloak. Only their eyes are visible, glinting with enigmatic wisdom.
  
  FIGURE
  (riddling)
  In a house of knowledge, what has no walls, yet holds the universe within?
  
  Ethan pauses, pondering the riddle. The camera shifts to a high angle, showing the vast library sprawling beneath them, emphasizing the smallness of Ethan in his quest.
  
  ETHAN
  (whispering to himself)
  No walls...
  
  The camera cuts to a CLOSE-UP of the FIGURE's eyes, which seem to hold a secret.
  
  FIGURE
  (softly)
  Time loops in circles, past, present, future—a story untold, yet known.
  
  The scene begins to shift, the edges of the frame blur and distort. We hear ETHAN's earlier conversation with a mentor, echoing faintly, as if from another time.
  
  MENTOR'S VOICE (V.O.)
  Seek the forgotten, where shadows dance with light.
  
  Ethan stands abruptly, knocking a book to the floor. The camera zooms in on the book's cover, revealing a symbol—a key intertwined with an hourglass.
  
  ETHAN
  (realizing)
  The map... it's in the stars.
  
  The FIGURE nods, vanishing into the shadows as if never there. Ethan races to a nearby window, gazing up at the starry sky. The camera pulls back, transitioning to an aerial view of the library, illuminated by the constellations above.
  
  FADE OUT.
