Sector Map of the Milky Way
This map shows the various sectors of the galaxy. The galaxy is split into eight radial sectors, each of which has five zones which are Core, Inner, Outer, Rim, and Perimeter. The borders of each zone occur in 10,000 light years steps from the centre of the galaxy.
Political Map of the Milky Way
This map shows the divisions of the galaxy according to the The Groombridge Accord and The Federal / Imperial Treaty. According to the treaty, no one may hold any claim to any core sectors. This is a moot point since the core sectors have too much radiation for a colony to survive anyway.
