The score complements the film’s dualities: airy, ethereal motifs for lunar sequences; bold, percussive themes for solar moments. Sound design emphasizes texture — creaking wax, wind over craters, metallic clangs — which deepens immersion. Music never overwhelms the emotional beats; instead it underlines character growth and the story’s quieter revelations.

Mune cannot lift a boulder. He cannot fly without help. But he can listen, empathize, and think laterally. His victory over Necross comes from understanding light reflection—an intellectual and creative solution, not a violent one.

When the Guardians of the Sun and Moon are chosen by a ritual, the sun’s chosen is a brash, proud warrior named Sohone; the moon’s chosen is Mune, a shy and clumsy apprentice with uncertain origins. The balance of light is shattered when a scheming wax-obsessed being, accompanied by a sinister thief, steals the sun, plunging the world into darkness. Mune, Sohone, and a resourceful teenage human girl named Glim join forces to recover the stolen luminaries. Their quest tests their strengths, reveals hidden truths, and forces each guardian to accept who they are and what they must protect.

Mune is not made of flesh or stone; he is constructed of what looks like black, spongy foam. He leaves behind little crumbles when he walks. He is squishy, bouncy, and afraid of the dark. In most myths, a Guardian of the Moon would be a creature of darkness—comfortable in shadows. Mune is terrified of them. He carries a small lantern (later replaced by the matchstick) to fight off his own phobias.
