Dominions roster

Named Dominions and peer polities of the Centauri Cluster in Exodus: The Archimedes Engine — Celestial multi-system powers, nomad threats, annexation targets, and ancient engineers whose works still move planets. Each living or major historical Dominion has a dedicated page. Full spoilers.

What is a Dominion?

In Cluster politics a Dominion is a Celestial-scale polity: not a single planet, but a civilization with fleets, archons, and Great Game interests across multiple stars. Celestials are the people/clades; Dominions are the states they form. Today’s great Dominions (including the Crown) are shadows of older empires; Gates of Heaven, helium economies, and Archimedes Engines are the board they fight over.

Major living Dominions (novel stage)

  • Crown Dominion — Imperial Accord of Now and Forever Queens; Kelowan capital; HeSea monopoly; main setting
  • Heresy Dominion — Hexapod Celestials; Olomo; Wynid ally; Dolod discovery & science
  • Talloch-Te Dominion — Nomad traders / shipbuilders; Sahdiah; Verak ally; Traveler tasking
  • Mara Yama — Nomad citadel Celestials; external threat & hardline pretext
  • Gomatu Dominion — Dyson-sphere builders; Dolod’s original destination vector
  • Uthara Dominion — Annexation target in Helena-Thyra’s expansion plan (with Capo Frois)
  • Ratarajan Dominion — Hoa Quinzu authority; warns Diligent of Mara Yama refuel

Ancient / legacy powers

  • Elohim — Dawn Era planetary engineers; Archimedes Engines; Eden worlds

Also named in deep past without full dominion pages: Pouli (Formation War enemies associated with strangelet weapons), Détenir (extinct rulers of Lidon in Traveler lore), and other Remnant-era civilizations. See Travelers and Celestials.

Crown Dominion member seats (not separate Dominions)

These are royal houses / systems inside the Crown Dominion under the Imperial Accord — each with a Now and Forever Queen — not independent Dominions:

The Dominion has six founding systems and, after Zuberi’s extinction, five living royal houses. Client human worlds (Gondiar, Anoosha) sit under Crown power without being queen seats. Overview: Crown Dominion systems.

Strategic places often confused with Dominions

  • Capo Frois — annexation / gate theatre; Diligent endgame vector (not a full dominion page; named in hardline plans and flight paths)
  • Tinaja / HeSea / Pillar of Zeus — Crown helium resource theatre shared with Heresy research interest
  • Hoa Quinzu / Kajval / Kingsnest — campaign systems outside everyday Crown client life
  • Malakbel / Lidon — Traveler and mercenary origin nets; Formation War / Détenir history
