The Meridian Cluster

The year is approximately 2500. Humanity has spread across the Milky Way, built hyperlane networks between the stars, and split into three factions that cannot agree on what civilization should look like. The Solar Alliance is the largest — over a hundred worlds governed by a democratic council that answers, in practice, to six dynastic families who control the infrastructure everything runs on. The Commune of Free Systems broke away a century ago to build something based on cooperative economics and direct democracy, and has been fighting a low-intensity war with the Alliance ever since. The Valor Empire was founded by an explorer who discovered a Precursor starship of extraordinary power and used it to carve out a feudal kingdom where technology flows from the throne. Three alien species share this space. The Orions are small, four-armed, and integrated into human society in technical roles — legally equal citizens whose experience of that equality varies. The Spareen are genetically self-modifying aliens carrying inherited knowledge from an intergalactic origin they cannot fully remember. The Thrisk are enormous, communal, and fundamentally incomprehensible — they do not recognize borders, do not honor treaties, and do not regard humanity as peers. Two rare resources fuel everything: Grunstein for faster-than-light travel, Chengtou for advanced technology. Rejuvenation treatments let the wealthy live indefinitely. The Precursors who built the technology that shapes the Cluster vanished millions of years ago. Earth was evacuated three centuries back and its survivors were left behind. You can be anyone — a station mechanic, a frontier captain, a corporate heir, a Commune soldier, an Empire commoner, a Spareen wanderer, or an Orion engineer. The Cluster is vast enough for any story you want to tell.
