Factions

Powers and peoples of the Centauri Cluster in Exodus: The Archimedes Engine — post-human Celestial dominions, human layers under them, and the movements that push back. Full spoilers throughout.

For how a Dominion differs from a royal house, and for the Crown’s member seats, see the Dominions roster. For the individual queens, archons and court figures who hold these powers — and for Celestial naming conventions — see the Celestials roster.
