The Esonar Confederacy is a somewhat loose alliance of planets centered around the capital world of Esonar Prime. It includes many highly industrialized worlds, including the smoggy, toxic planet Mirond, Alher, a world that is almost entirely dedicated to technological research and development, and the capital itself, a dark, cold world almost entirely covered by a planet-wide city.

While The Confederacy is technically a representative democracy (at least partially), it has arguably degenerated into a fully corporate-ruled system where the representative government governs in name only.

The Esonar Confederacy has been in a constant state of intermittent conflict with the Aethi Imperium since its establishment. Before this, the Esonar planetary military attempted several forceful colonization efforts on Aethis, the first indirectly resulting in the Imperium's founding.
