Looking for a suitable system

Daddicus

I need some help finding some location. I've looked over http://travellermap.com/, but can't figure out how to find out if such a place exists.

First, the system needs one of:

  • 2 habitable worlds, or
  • 1 habitable world, but any other planets are undefined.

Second, each world also needs to either

  • have an occupied moon, or
  • that the moons for that system have not been defined.

Finally, the system should have another system 1 or 2 hexes away that greatly desires the goods of the original world. In other words, players with goods from the original system are almost certain to profit selling them at the nearby system.

I can generate my own easily enough, but it would be really nice if I could use an existing system somewhere in human-owned space.

Background: I'm developing a mini-campaign designed to help brand new players acclimate themselves to Traveller.

The campaign starts on a world that's enslaved by a small population on one of its moons. Eventually, the players break free of the shackles of slavery by defeating their overlords on the moon.

Then they discover that their world and moon aren't the real world in that system. They were merely on a copy of the real slave world and another moon populated by overlords, who had previously expanded their operation to the planet the players called home.

The first time they broke the yoke, it was for their own freedom. The second time will be as liberating heroes freeing the downtrodden.

Once they've deal with the villians, they gobble up a cargo bay full of trade goods, which their newly-freed friends are more than happy to give them for all they've done.

Naturally, whatever loot they are given has to sell somewhere, so they must therefore become star-farers. Travellers, if you will. And, to whet their appetite, this first foray to the stars should be profitable.

So, I need a system with two populated worlds and two populated moons, near another system that buys their stuff. (But, I'll accept a system that hasn't been fleshed-out officially -- MOARNed, if you will.) And, I would prefer to set it inside the Imperium or other human-dominated area. But, I can't seem to get the map's search to find one for me.

Any ideas?
 
Traveller's model has typically been to show the one dominant world and assume that any other occupied worlds are subservient to the "Main" world, or at least cannot challenge it in terms of population or technology.

The situation you describe could still fit into that set of assumptions, but the two worlds would probably be quite different since they wouldn't have the same orbit. You can put them in the same orbit, but you almost have to acknowledge that the "Ancients Were Here" to do so.

In different orbits within a wide habitable zone, one world will be warm, the other cold. At least relative to each other.

Both having moons is no big deal. Both having habitable moons is certainly unusual, but not impossible.

Keeping the "main world" assumption can be done and still keep the worlds close in details. The Main can be at the bottom of Pop 8, while the Alt is at the top of Pop 7, for example. The two can be one TL apart or more, but not the same, and the Main has to be the higher. The Alt has few Government code options, but 6 (colony) works even if the inhabitants don't realize it.

With that in mind, pick a system in which the listed world matches your vision for the primary world, has a nice warm sun (to get a wider habitable zone), and a Rich or High Pop neighbor within a few hexes.
 
Or you can just ignore the rule about no two mainworlds in a system, since there is no reason why two worlds in the same system can't both have the same (highest in the system) population level. It's purely a simplification for the sake of easier random generation. If you need two evenly matched worlds in the same system, just go for it.

By fiddling with albedo and greenhouse effect it's fairly easy to fit two habitable worlds (inadjacent orbits) into a life zone. (Getting three is difficult (but doable)).

What about having the "mainworlds/moons" all be satellites in orbit about a Gas Giant or Brown Dwarf that is in the habitable zone? Or for that matter, a binary star system, with each star having its own independent habitable zone?

This sounds like a far simpler solution to the problem. If Regina is a moon orbiting a gas giant, then two in the same orbit could fit the bill quite neatly.

First, I think the gas-giant idea is a good one, if you can live with it.

Regardless, I'd say create what you need and plunk it down somewhere in the Spinward Marches.

On the Gripping Hand, I did a similar "Traveller-and-Traveller5 Acclimation" adventure in the Deneb sector, in the Rhinom system. There are two habitable worlds in the system: the outer world is the mainworld, and is cold, with mild equatorial zones. A noble is basically being a dictator to the secondary world, which is a warm farming world. Jungle territory is being used for farming and refining various export crops: exotics and high-value rares, some of which is narcotic. Some of the work areas are essentially slave camps run by thugs.

And the Evil Baron oversees the whole thing via a planetoid he's put in orbit around the farming world. And yes, that adventure eventually wrapped up with an infiltration and assault on the planetoid base.
 
Balkanized world could be understood as many countries on one continent, countries on different continents, and why not different world?.

Nobody chalenge that Norway and Quatar could exist on the same planet, so what is the big deal with different weathers on a cold and a hot worlds... Narvik is just the equatorial heaven of the cold one and Quatar, the most septentrional and coldest major town of the hot one?

Have fun,

That will work too. Only, be careful not to put the worlds too close to the gas giant. A couple of the supposedly inhabited moons in orbit around Assiniboia would actually be molten from the tidal stresses.

Great ideas! Thanks!

The history is that there was originally one main world. The indigenous people eventually colonized one of its moons. But, then sometime later a chemical mixture is found on the main planet that renders people essentially mindless drones. The guys on the moon exploit this, and create a whole planet of slaves to service them. They have to keep maintaining the chemical mix, but that's a small price to pay for most of a whole world's planetary income.

Eventually, they need breathing room, so they expand to another habitable, but then-unoccupied world, which just happens to have a moon that can be made into a base of operations. This second moon is a semi-terraformed city, run by the mafia from the other planet. I envision it being a domed city, from which you can guess at the event that changes the status quo.

Our heroes come from that second world. An event occurs that makes their overlords be not quite so ... well, living. So the chemical mixture doesn't get maintained, and eventually wears off. The players have to figure out who they are, how they got there, and how to get off the dismal rock they find themselves on.

Anyhow, all that gives a backdrop for why 2 worlds and 2 moons. The second world and moon pair isn't as developed as the first (probably due to being colder, as some mentioned above -- great idea!)

Putting it near a rich planet makes a lot of sense (thanks).

Cool! Thanks!!!
 
A domed city style also means the second moon does not need to be T-Prime, which makes the arrangement a bit more common.
