Historical Record
In 10219 regency and ecology collide. The hopes of a generation meet the stubbornness of deserts, canals, and weather that answers to forces older than the Imperium. Nobles rally factions; sietches debate; priesthoods and planetary ecologists argue over timelines measured in lifetimes versus centuries. Public squares fill with pageantry and protest in the same week, and diplomats discover that the most consequential meetings often happen in kitchens and caves, not palaces.
Historically, the year teaches scale. Everyone wants swift outcomes; the planet insists on patience. Reports from Arrakis detail water discipline, seed stock, and the ethics of altering a place to suit human comfort. The record also tracks the education of heirs under pressure—how a polity trains young leaders to hear counsel, hold their nerve, and distinguish between vision and vanity.
