What if the only thing you love is slowly sinking beneath you

the prompt

A little girl discovers a glowing book in a midnight library. When she opens it, a galaxy flows from the pages onto the floor, becoming a glowing path. She follows the path deep between the bookshelves, then opens a hidden door and sees a garden floating in space. 15 seconds, starting with a quiet close-up and slowly expanding into a magical wide shot, mysterious, gentle, cinematic.
A young girl of 23  image1 (shoulder-length wavy blonde hair, dirt-streaked face, wearing a tattered short-sleeved brown tunic and a silver pendant necklace) desperately tries to save her beloved white horse Artax image2 from sinking into the deadly Swamp of Sadness. The environment is a dark, fog-shrouded dead marsh filled with twisted blackened trees, murky black water, and an oppressive atmosphere of despair. Preserve the exact character designs@image1 , horse appearance@image2 , clothing, mud, fog, and lighting throughout — never redesign them.
This film is pure emotional intensity: slow, heavy camera movements, tight close-ups on faces and eyes, wet mud and water textures, and an overwhelming sense of helplessness. No text, no graphics, no modern effects — pure classic 1980s fantasy tragedy.

Atreyu desperately tries to save Artax from the Swamps of Sadness, pulling the reins, shouting, crying, and comforting his terrified horse as it slowly sinks.

Cuts 03–08: she image1  pulls desperately against the reins, shouting “Artax! Come on!”, “Please! Get up!”, and “You’re my friend!”

Cuts 09–16: Tight emotional close-ups. Tears and mud cover Atreyu’s face as she begs Artax to fight the sadness, whispers “Fight it, Artax… please,” strokes his muzzle, and says “I need you…”

Cuts 17–24: Artax sinks deeper. she image1  presses her face against the horse, openly sobbing and whispering “Artax… please…” and “I love you…” before wrapping her  arms around its neck.

Cuts 25–29: Artax’s head reaches the surface, then begins disappearing beneath the black water. she@image1  pulls with everything she has, screaming “NO!!” and “ARTAX!!!” as the horse vanishes.

Cuts 30–36: Extreme close-ups of Atreyu completely shattered, tears streaming down her face. she stares at the empty swamp as ripples slowly disappear, her reflection fades, and the frame becomes completely black.

Use slow, restrained camera movement, lingering close-ups, realistic mud and water interaction, terrified horse expressions, subtle breathing and crying, sparse mournful strings and low drones that swell only during the screams. No upbeat music, no modern effects. Maintain strict character and horse consistency throughout.
