New style for the Random Subsector Generator

The Random Subsector Generator has been updated. It now outputs an image in PNG format instead of ASCII.

Old and New Style
Old style to the left | New style to the right

The new style outputs a quite large image, 2066px × 2922px. The hexes are big enough include UWP and Trade Class. I have used a purple colour for UWP and Trade Class so that this extra information won’t stand out to much.

For the new style there are 10 types of planets. These are the same types that are used in the Traveller Universe program.

Subsector Generator Update

I have updated my Random Subsector Generator with a new “race“.

If you select Zork, you will get a subsector with planet names that are inspired by an intrepid space explorer in a very small ship (that usually crashes.)

I have used 1:st order Markov Chains to create the new names. (Higher order create too few names since we start with so few planets.)

Glortero Subsector

From the comic, I also guess that the planets should be quite small and that the tech level is high. So without creating illegal values, I have added a small bias for this.

Subsector SKA-1979

On this day (19 October 1979) , 40 years ago, the albums One Step Beyond… by Madness and the album The Specials by the Specials were released. (Read more here.) This is an ATU subsector map I made to celebrate this:

Florensa Subsector

One of the more popular pages at the Zhodani Base is the Random Subsector Generator. With the help of the generator, some text editing and the post function at Traveller Maps and some editing using Gimp, I created this subsector.

I made this subsector to try out the region xml-tag that is used at TravellerMap for nebulas. But then I liked the subsector that I have made, so I decided to make it prettier using an image of a real nebula.

Florensa Subsector
The Florensa Nebula is in the center of the subsector. This nebula is a navigational hazard. (Add +2 for misjump to/from Florensa and +1 for misjump to/from any of the six surrounding hexes.)

Three interstellar powers are present in the subsector. The Portuna Federation, the Caponiana Free State, and the Elekto Zardom.

All three interstellar powers have signed an agreement that have defined the Florensa Nebula as a space preserve. No ships are allowed to go there except for scientific missions.

Short Write-Ups:


Silestina is the local capital of the Portuna Federation. Trade in illegal gems from the Florensa system has attracted lots of settlers. The planet is ruled by Duke Ostretto who is not very popular and that have risen the law-level to C to protect himself.

Florensa X000000-0

At Florensa there is a thin asteroid belt orbiting a neutron star at 80 AU. There are a few research stations in the belt. These stations observe the neutron star and the nebula. The stations are usually unmanned.

In some areas of the Nebula, there are lots of valuable minerals. It is possible to find gems like Diamonds or Sapphires. There are also noble metals like Platinum, Gold, Iridium, and Osmium. Some radioactive  can also be found.

In a few locations in the nebula, 2000-year-old (non-human) mining equipment have been found. Due to micrometeorites and radiation, these doesn’t work anymore, but they seem to have been more advance than what any of the current interstellar powers can produce.


Paleria is the local capital of the Caponiana Free State. Trade in illegal gold from the Florensa system has attracted lots of settlers. Paleria is controlled directly from Caponiana.


Armiona is working as some kind of local capital of the Elekto Zardom. Armiona is a huge asteroid belt and each asteroid have its own government. There is no central control. Trade in illegal radioactives from the Florensa system has attracted lots of settlers.

Subsector from a Map

I have been asked how I made the maps of Lancaster and Chambersburg Subsectors. In this post I will describe how I did it.

(I have also done the same for Ireland. I work on a version of Denmark and south Sweden.)

First I find the area I want to map on Google Maps (or any other map). I zoom to the level I like. 10-20 towns (or places) in the area is about right. Make a screenshot of this.

I use a transparent subsector map that I have made using quickhex.

I use a good image editor that can handle layers. (I use GIMP, which is free.) Then I open my screenshot and place the transparent map on top of it as a layer. (I can move it a bit until I am happy where the towns are in the subsector.) This is what it could look like.
