Space Opera: The Terran Sector

An updated map of the Terran Sector for Space Opera, or in fact any other game using a 3D map. The map is a 200x200x200 Light Year cube, centered on the Sol System.  Ninety stars are shown. It is important to remember that this volume of space contains over 30,000 stars.  I have included a spreadsheet showing stellar distances. I would not print it out unless you have an A1 sized printer that can do floor plans.  As far as a description of each system – I will leave that up to those who feel they need one. I was going to just use standard Traveller for this task. There are some pretty cool system generators out there that can do this for you in seconds.

If you would like a copy of the actual spreadsheet (or a blank for doing your own star sectors) then please contact me and I will send you a copy.

Space Opera: Terran Quadrant Map

I am a long time fan of Fantasy Game Unlimited’s Space Opera universe. I have done an earlier post on this game giving a brief overview of the background. It was an incredibly complex game system – so much so that I think that I only ever played one game using the mechanics and in the end we switched back to Traveller. But as I said, I loved the setting.

The module Star Sector Atlas 1: The Terran Sector came with a large fold-out map of the Terran Quadrant. For someone used to Traveller subsectors a gaming map encompassing 99,840,000,000 cubic light years was pretty amazing.  I have several copies of the original Quadrant map and wanted something electronic – so I knocked one up yesterday.

I changed the format somewhat but tried to keep to the original as much as possible. I have added my own Hadrian Sector to the map – a post on the work on that Sector will be made in the next day or two.

For my new campaign I am using GURPS Space as the basis but like most things I do there will be a lot of hybridisation going on. For example, I have not decided on what system to use for planetary and system generation. For simplicity I was thinking of sticking with Traveller but I have since found some pretty cool GURPS Space generators that can knock out a million systems in no time at all.

Warning: This is a big file – the map is 4688×3632 pixels and is 1.25Mb in size.  The orange line is the approximate edge of the Orion Arm.  Galactic Centre is towards the right of the map.  The map is centred on the Terran Sector which is at location 000/000/000.

Distances are easily computed by simply applying the forumla: distance-three-coordinates

Or even more easily by going to this web site and putting in the numbers. For example, to compute the distance between the Terran Sector and the Hadrian sector (Terran 000/000/000 and Hadrian 600/000/300) plug those into the website linked to above and get 670.8LY.  Quite a haul in a cargo freighter crawling along at 10LY per day.  Over two months. Only a few weeks in a fast courier though.
