Apprentice Barnaby and Senior Technician Luma confront a crisis at the Great Prism Array where Conceptual Saturation threatens to shatter the light infrastructure. The accumulation of pure, undiffused belief causes the light to become dangerously certain. To prevent visual collapse, Barnaby risks deploying a forbidden artifact from the Lowest Tier of the Wonder Archive: the codified essence of A Necessary Chore, an artifact of absolute conceptual inertia. The deployment successfully grounds the light, diffusing the saturation, but the conceptual weight spreads throughout the facility, introducing an overwhelming feeling of mandatory labor and apathy, effectively stopping all spontaneous joy. Luma notes that this new systemic resistance to spontaneity is now affecting other departments, specifically referencing the now-motivated-by-tedium Pipkin Junior.
