The Concordat of the Closed Sky

The Concordat began as an emergency committee during the Ashfall, when poisonous clouds, surface fires, and magical storms destroyed the old kingdom. Its founders organized the last functioning shelters, but they also selected which communities would receive admission. The first decades were marked by brutal necessity. Food was rationed, births were regulated, and entire families were moved away from unstable tunnels. These policies prevented several settlements from starving, which created the Concordat's enduring reputation as the institution that saved civilization. After the Ashfall storms subsided, the founders refused to dissolve. They argued that the surface was still dangerous and that only centralized control could prevent a second Collapse. The Concordat absorbed local councils, standardized dialects and calendars, and imposed a single legal identity system. It also rewrote the history of the disaster, presenting itself as a neutral rescue authority rather than a selective survival regime. Its first great triumph was the reopening of the Deep Aqueducts, which connected six major settlements and ended a century of isolated famine. Its greatest setback came during the Saltwater Revolt, when miners discovered that their district had been denied clean water so that the capital could maintain ornamental reservoirs. The revolt nearly toppled the government. The Concordat survived by granting limited local assemblies, then placing its own observers inside every one of them. The defining watershed moment was the Green Door Incident, 61 years ago. A survey team opened a sealed surface passage and returned with living plants, clean rainwater, and proof that at least one valley had recovered. The ruling council ordered the team imprisoned and publicly declared the expedition a mass hallucination caused by toxic exposure. Three council members objected and disappeared. Since then, preserving the underground order has become more important than the original mission of survival.
