40kRPG themed? I'm going to be running a sandbox-y rogue trader campaign early next year where the explorers will start off from Holy Terra and have the entire imperium to explore, but its possible they might want to hang out in the capitol sector to gain resources and political connections.

Assuming you mean the Sol Sector and not Segmentum Solar (which is a larger area that includes Sol Sector).

None of the RPG products delve into either the sector or segmentum. For the sector, there's not a lot of worlds/systems known, all I can find right now other than Holy Terra/Solar System is Cthonia.

Keeping in mind that the Imperium supposedly encompasses a million worlds, you probably don't even need it at a sector level. Just search images.google.com for "Map of Segmentum Solar" and you should find some fan maps that have enough worlds to fill a few campaigns.

I'd say you can just make up your own map, there doesn't seem to be much info that would contradict you at this point. (And waiting for someone to prove me wrong I hope).

You may want to try some of the TT dedicated fan forums, not just here at FFG.

Thanks for the info. Yes, I was referring to the sector and a lot of the wikis online refer to it as the Solar Sector, with earth's system being the Sol System.

I might just go ahead and photoshop up a map in the style of FFG's.

One way to do it might be to visit wikipedia's list of nearest stars for inspiration for the names of a lot of worlds and subsectors in the Sol Sector.

Another good source might be the list of discovered exoplanets.

The Sol Sector, as the seat of the Imperium, is going to be a very unusual Sector. If Sectors like the Gothic, Scarus or Calixis Sectors (all of which have a lot of background on them in the canon) broadly represent a "typical" class of Sector, the Sol Sector is going to be very different.

You're looking at the heartland of the Imperium, the centre of the greatest empire humanity has ever known. Think Rome at its height (or Rome just before the collapse, depending upon your viewpoint.) The place will be far richer than most Sectors, with a larger and more elite military presence. It is also likely to be relatively peaceful; the massive Imperial military is unlikely to tolerate strategic threats in the Emperor's back yard. However, to some extent it will resemble the Calixis Sector in that there is likely to be a huge amount of intrigue and backstabbing going on.

Most Sectors consist of 75-200 populated worlds in a region of space filled with tens/hundreds of thousands of empty, useless star systems. The Sol Sector, one imagines, will actually be a lot more crowded. There could be 500 or more populated worlds. A lot of worlds that in the wider Imperium would be regarded as uninhabitable rocks would have been terraformed/mined/occupied in the millenia preceding the formation of the Imperium, and then reconquered during the Great Crusade.

One also imagines that you'd be looking at a very large number of ancient, very powerful hive worlds, perhaps in subsector clusters of 25-30 at a time, with populations in the hundreds of billons or even trillions. Just for logistical reasons you'd also have a lot of agri worlds just to keep these massive populations fed!

Many of these Hive worlds would be given over wholly to some of the Imperium's larger institutions. So you might have a hive world which functions as the HQ of the Adeptus Munitorum, or the Imperial Guard General Staff, or another which controls all Administratum records for an entire Segementum.

The Imperial Navy would also presumably have a massive presence: the Battlefleet Solar is an elite formation within the Imperium, and one imagines you'd see a lot of dock worlds and military space stations of huge size.

There would probably also be a slightly higher proportion of Space Marine homeworlds, from Chapters with a history of fanatical loyalty to the Adeptus Terra hierarchy. More fractious or troublesome Chapters will have been exiled to the fringes to conduct crusades.

You probably wouldn't see a lot of frontier worlds, death worlds, or "unknown" worlds. Even the "rock" systems - those thousands of empty systems which consist of stars and uninhabitable, strategically useless planets, are likely to have a small military presence. There probably aren't a lot of penal worlds, either; if a world can support life, it'll be filled with useful administrators and scribes, not useless prisoners. Convicts are probably shipped to penal colonies outside the Sector.

From a Rogue Trader's perspective, it's going to be a place where there's a lot of red tape. Their ship will be stopped an searched on a regular basis by the Navy for security reasons. One imagines that all ship traffic is very heavily regulated. After all, if you drive your vehicle in a suspicious manner near the White House or 10 Downing Street, expect to get stopped and searched...this would be the 40k equivalent!

To some extent, it's not the ideal place for a Rogue Trader. Their warrants of trade may make them big fish on the fringes, but in the Sol Sector, they'll be minnows swimming with sharks...here there are high powered individuals who outrank them substantially, and who have centuries of experience in militarily and politically outmanoeuvring their opponents. A Rogue Trader would be regarded at best as a noveau riche middle class outsider by the powers that be in the Sector, even if their dynasty is thousands of years old.

That said, it would make for a fascinating break from "normal" Rogue Trader campaigns, with a good deal of high level intrigue and scheming. Sounds fun! And given the high quality of your Eye of Terror map, I'd love to see the Sol Sector map when you've done it!

Please do, I look forward to seeing one.

Lightbringer covers a lot of salient points. A rogue trader would have to have serious wealth, incredible deeds or truly valuable artefacts to impress the inhabitants of the Sol system and surrounding sectors. Preferably more than one of those. Terra itself is incredibly densely populated, with both people and organisations. Lots and lots of political intrigue and subterfuge is the order of the day, because anyone openly acting against their enemies becomes a target for too many others.
