For a game in the not too distant future or maybe for the 2300AD. The Baltic Loop is a vactrain that can travel at supersonic speeds.
The distance between the stations are only 2-3 minutes. The train runs in both directions. 4 trains runs in each direction. This means that a new train arrives at the station every 9 minutes.
The Island Games is held on Gotland, Åland and Saaremaa. The participants from many other island arrive by air in Helsinki or Stockholm. Now the PCs must help one confused team to go to the correct island using the Baltic loop.
The Baltic Loop is closed down one day to try to set a speed record (and beat the Californian HyperLoop). Agents from the Californian HyperLoop tries to sabotage the record attempt. The PCs must help with the record attempt and stop the Californian agents.
Courland has just become an independent nation. The Latvian flag has to be replaced on every sign at the loop. Latvian agents are trying to sabotage this. Polish agents turn the Courland flags upside down to make them look like the Polish flag. The PCs must stop the Latvian and Polish agents.
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.
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.
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.
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.

This post is about trigonometry in the hex-maps used for Traveller subsectors. The summary for those who hate maths is that a jump-4 is actually only 3.46 parsecs if you take the shortest route.
As you can see in the image above is that if you want to go from point X (0503) to point Y (0101) it is a jump-4. The distance is 4 parsecs.
But if you wants to go from point X (0503) to point Z (0103) it is also a jump-4, but the distance is actually shorter since you are zigzagging when you are counting the hexes following the dotted orange line.
How much shorter is it? If we use Pythagoras, then:
a2 + b2 = c2
b2 = c2 – a2
b2 = 16 – 4 = 12
b = 3.46
If we use trigonometry, b = 4 * cos(30) = 3.46.
In the Adventures of the Starship Notorious the crew meets a very talented jump-drive scientist that helps the crew improve and calibrate their J-3 drive so that it can do 3.46. This will only work if the ship is unloaded and if a special jump-program is run.
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. Continue reading Subsector from a Map→
