Maps of the Terragen Sphere
A selection of maps of the Milky Way Galaxy showing the location of the Terragen Sphere and various polities within that region
The Orion Arm and Proximity
|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
The Milky Way Galaxy and the location of Known High Energy Emitting Civilisations
This map shows the various arms of the Milky way galaxy, the extent of the Orion Arm Civilisation and some of the alien High Energy Emission Civilisations which have been detected outside the reach of current exploratory spacecraft.
Please note that the grid is centred on Sol and each square represents ten thousand light years.

Locations in the Inner Sphere, viewed from above the Galactic Plane from Galactic North. Note; the grid has a scale of 10 light years per square
This view shows the Inner Sphere from a viewpoint above the Galactic plane and to rimward and counterspinwards of Sol. The location of Sol is marked by a red diamond.

Please note- in this map, galactic North is to the bottom- as is the convention in the Communion of Worlds and elsewhere

- Galactic Directions - Text by Anders Sandberg, amended by Steve Bowers
Planetary terms like north, south, east, west, are insufficient for referring to directions within the galaxy. Instead, the a different set of conventions have achieved widespread acceptance when referring to direction.
