Elmsworth and Juniper, apprentices in the North Star Projection workshop, discover that the chromatic gels are failing due to the ongoing resonance interference, resulting in a dull cyan hue instead of the required true blue. Juniper identifies the need for the Stardust Infusion, a spectral stabilizer stored in the sealed Observatory Annex. The Annex requires a lock combination based on the frequency of the silent Solstice Chime. Elmsworth discovers that friction from a non-metallic reindeer hair cloth can momentarily restore the light's true color. This sparks an idea: using a non-conductive material to mimic the chime's sound. They use a thick, crimson silk ribbon, running it rapidly across the frequency lock panel. The resulting high-pitched vibration successfully opens the Annex, revealing the Stardust Infusion, which they hope will stabilize the light projection before the ceremony.
