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

Artistic Map
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.

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.

Star Maps

A series of maps zooming in on the vicinity of Sol in the Orion Arm. The blue-green circles mark 100, 200, 300, 400, 500, 1000, 200, 3000, 4000, 5000 and 10,000 lightyears from SolSys.

20000 ly - the large structure of the arm and the neighboring Perseus arm (left) and Sagittarius arm (right) can be seen. Eta Carinae is near the lower middle border.
