In this film, Yves chooses a Solar System as the setting because of its parallels with the human body—both are beautiful, interconnected systems that we rely on, but that we don't fully understand. He then includes an orrery—a mechanical model of the Solar System—so that the viewer can see exactly how the system works. From here, there's a wide-sweeping tapestry of characters, each with carefully considered shapes and textures and design-oriented origin stories: there are the giant ethereal creatures inspired by the aureola boreales who spin the globes; the fiery sun keepers in the mould of tiny sparks of fire that form the sun when all together; the pointy-headed star keepers in the shape of stars who are responsible for lighting the path before the moon-carrier.
