The Moon Cracks Open is one real Moonfall match, recorded from the first turn to the last. Kitsu, The Ninefold Spark, a nine-tailed fox, plays Einar Skjoldr, The Horizon Reaver, on the cliffs of Sky-High Aerie. The song over it is made from lines the game's AI storyteller wrote during that match. The film ends on the manga storybook the game made of it.

The title still of The Moon Cracks Open, a warrior pulling the moon down on a chain. — The Moon Cracks Open (1:08). Music and one shot made with AI; the game footage is the real game, recorded. Pressing play loads the film from YouTube.

A match, as it was played

Neither player knows how a card will land until the storyteller rules on it, and the film keeps those rulings as they came:

The fog. “Lose your way in the mist,” Mist Weaver whispers, wrapping thick fog around Einar Skjoldr. Blinded by the clouds, his footing slips on the aerie's edge.
The wyvern. “Swoop and burn,” Einar roars. Thunder Wyvern plunges through the fog, raking talons straight across Kitsu.
The turn. “Look up,” Kitsu purrs. The Moon Is Kitsu swells, bleeding silver fire across the sky, and Einar's warband turns its blades toward its own summoner.
The moon. “Pull it down,” Einar roars. Pull Down the Moon drags the glowing sphere out of the heavens and crashes it into the aerie.
The answer. “You opened the sky — now bleed for it,” Kitsu purrs. Return the Wound tears the lunar scar open across Einar's armor, and Kitsu wins.

The words became a song

Every line sung in the film is one the storyteller wrote in this match; the music was made with AI around them. That is the idea at the heart of Moonfall: you choose what your card does, and an AI storyteller decides what happens and writes it down. How Moonfall's AI Game Master works explains the rulings. The Serpent Lets Go looks at how the words of a single card set the stakes.
