The Orion Arm and Proximity

Image from Phil B

An artistic interpretation of the Empires and other volumes within the Orion Arm and environs. Although the borders between the empires are displayed as discrete limits in this interpretation, in practice the various empires merge into one another and change over time as the various systems change allegiance. Note as well that this two-dimensional representation does not show the full extent of empires which overlay one another - the Red Star M'Pire overlays the much larger Solar Dominion, for instance, and the Mutual Progress Association and the Keter Dominion are similarly stacked one above the other
