Six months after the Free Navy fleet vanishes, Earth, Mars, and Belt figures gather at Ceres to begin a political settlement and confront the need for a new gate economy.
The conference on Ceres Station assembles the surviving powers after the collapse of the Free Navy's concentrated fleet. Resistance continues in the Jovian system, Rosenfeld faces the first major Earth-attack trial at The Hague, Anderson Dawes has been captured, and Sanjrani has surrendered at Tycho. Yet the wider political mood is exhausted enough to recognize that the war has ended even before every last armed holdout is removed.
Its immediate context is precarious. Laconia repeats a sovereignty warning through its gate while Earth contains the route with battleships, and the damaged solar system needs supplies from the colonies. Holden's proposal links that need to Naomi's discovery that gate traffic has a safe load limit and to the Belt's looming economic displacement. The initial framework suggests a limited-sovereignty independent union of ships, support stations, and services to regulate intersystem movement.
The conference's first public leadership question shifts when Avasarala seems to nominate Holden as union president and Holden nominates Michio Pa instead. That turn makes the meeting more than an inner-planet reconstruction scheme: it opens the possibility that Belters will choose and lead the work on which every system now depends.
A polished governor's-palace meeting center on Ceres with striped artificial-stone pillars, plants, formal uniforms and dress, servants with drinks, and a smaller triangular conference room crowded with officials and advisers.
The conference is the political hinge between the Free Navy war and a proposed system-wide order built around safe, Belter-led gate traffic.
