The coreward side belongs to the Pennsylvaani Confederation and on rimward side belongs to the Free State of Maryland. There is an ongoing cold war between these two pocket empires and there are various trade embargoes in effect. (In the spinward rimward corner are two worlds that belong to the Spinward Virginia Cluster.)

The total population of the subsector is just 30 million (Most of them live on Frederick). The highest tech-level is 11 at Frederick. This makes Chambersburg Subsector a backwater area of space.

Short Write-Ups:

Burnt Bases X200000-0 Red Zone

Not a lot is known about the red-zoned system called Burnt Bases. There is a rumor that something terrible has happened here, but this is not confirmed in regular history books. No reasons are given for why this is a red zone. The interdiction is controlled by the Pennsylvaani Navy.

Chambersburg B767687-A

Chambersburg is the Subsector capital on the Pennsylvaani  side. It is a nice planet to live on. There are no (known) flora and fauna that is very dangerous to humans. The atmosphere smells nice. If the system wasn’t in such a poor location it would have attracted a lot more sophonts.

At Chambersburg there is a university that is known for the study of history. Here you can find the experts on the big space battle at Gettysburg, a system 3 parsecs away that Chambersburg controls.

Carlisle C533589-8

Carlisle is an uninteresting stop between Harrisburg and Chambersburg, The atmosphere is so thin that compressor masks are needed outside. The world is poor and non-industrial, so it may be difficult to find a cargo.

Some farmers makes a very good brandy. This is a small-scale production and the Carlislesian brandy cannot be found at the starport. It is only available a few months each year and can only be bought directly from the farmers that make the brandy.

Gettysburg C000469-A

The asteroid system of Gettysburg is known for a major space battle that took place here about 150 years ago after the “Rimmies” declares war on the Pennsylvaani Confederation, the Free State of Maryland, and a number of other pocket empires.

Tourist tours are now available from the starport. The tours take you through the battle field and also to the space ship graveyard and to the eternal plasma monument. The tours use standard shuttles but with a transparent top.
