Aldebaran Revisited

I’ve developed regenerated sector data for Aldebaran, which Joshua Bell has been kind enough to host on Traveller Map. The old dataset was from Jo Grant's CORE data and unattributed. That dataset did several things right – it got the canonical names of subsectors A-D, and the stellar positions largely match up with the canonical dotmap, but otherwise I felt that the sector data didn’t reflect the few pieces of canonical data that were available on Aldebaran. And of course, it didn't have the many new T5 data fields.

Jon Zeigler evidently worked up an alternative dataset for an abandoned GURPS Traveller: Grand Frontiers supplement, which was to have covered Aldebaran. I contacted Jon a few weeks ago to see if he was interested in reviving that work, but it appears that his draft materials have all been lost. So I decided to roll up my sleeves and take a shot myself.

My goals for regenerating the Aldebaran sector data were to (1) reconcile the available canonical and semi-canonical sources about the sector, and (2) produce “new” sector data in the T5SS format using the T5 system generation rules.

Background

Classic Traveller Alien Module 6 - Solomani named subsectors A-D and detailed Home, the capital of the Solomani Confederation. Home’s exact location is not specified, only described as “in Aldebaran sector approximately thirty parsecs from Terra” and is shown in subsector B on a map of the Solomani Confederation circa 1111. Note that although the star Aldebaran (Alpha Tauri) was originally placed in the Cicero system (Solomani Rim 0938), this appears to have been retconned.

The descriptions of the rimward subsectors of the Solomani Rim make it clear that Jardin and Kukulkan subsectors were largely undeveloped until after the formation of the Solomani Autonomous Region (704), and the Near Boötes Cluster in Castor and Gemini subsectors was not discovered until “early in the history of the Rule of Man,” which begins in -2204.

The module also has a map of the Terran Confederation circa -2204 that shows the Confederation border as encompassing most of subsector A, all of subsectors B, C, and D, and small portions of E, F, G, and H. These borders are hard to explain, if Terran exploration hadn't advanced to the the rimward portion of the Solomani Rim by -2204. The map also shows four Terran settlements outside the Confederation in subsectors J and K. Sublight expeditions could have established outposts or colonies in those locations, but don't really explain the mystery of the border.

The MegaTraveller Referee’s Manual has a map of the Rule of Man (-2204 to -1776) that shows the border of the Terran Confederation as significantly smaller than the -2204 map in Alien Module 6. In this map, the Confederation only barely touches the rimward sections of subsectors A, B, C, and D. These borders are a lot easier to reconcile with the rimward history of exploration and settlement described in Alien Module 6.

DGP’s Solomani and Aslan explicitly located the Solomani capital at hex 1009, which matches the location shown on the CT Alien Module Map. But then Solomani and Aslan goes on to produce a dotmap of Aldebaran Sector that infamously excluded Home. That said, the dotmap alone has several interesting implications: the sector has relatively low stellar density, and Jump-3 is necessary to reach many, if not most of the worlds in Aldebaran—reinforcing the idea that the Terrans couldn’t have explored much of the sector until they developed J-3 late in the Interstellar Wars.

The dotmap also shows the borders of a couple of interstellar, presumably human, polities not otherwise detailed: the Malorn Union and the Winston Democracy.

Solomani and Aslan included write-ups of two large Solomani member-states located in Aldebaran -- the Grand United States of Quesada and the Third Reformed French Confederate Republic -- as well as a third member-state with influence on the region, the Boötean Federation, a socially liberal and economically powerful force in the Confederation. All three member-states get name checked in the d20 supplement Fighting Ships of the Solomani Confederation.

Quesada is a large member-state, a lively republic active in both the lives of the people and the political arena. The Quesadans speak fluent Spanish, with Anglic as a second language, and have a proud Hispanic heritage.

The French Republic is also described as a large member state, a union of three French member states and a number of independent worlds. Both the Quesada States and the Republic developed starship designs used by the Confederation Navy in the Rim War, which indicates these polities were in existence at least as early as 990 and probably much earlier.

Solomani and Aslan also names the world Inerria/Aldebaran, birthplace of the Solomani historian Albirto Majuan.

GURPS Traveller: Rim of Fire doesn’t provide any new information on Aldebaran Sector, though it gives us some hints. The book largely echoes the Classic Traveller information, though it walks back from some details in Solomani and Aslan, most notably the notion of a Confederation member-state and the Boötean Federation. The GURPS timeline features a much more fractious Confederation teetering on the edge of civil war.

The Mongoose Traveller Alien Module 5 - Solomani provides several interesting details but relatively little in the way of world data, with the exception of mentioning Willeson (Aldebaran 1216), a world in “Sephi Hydra” subsector. (Both the world and subsector names were in the original CORE dataset.)

Aldebaran is described as one of the Confederation's frontier sectors, “a less populous region ripe for future Solomani expansion. Their rimward subsectors are sparsely populated with many young colonies and border a region of space not yet claimed by any other major powers. The population is 90% pure Solomani; the rest are mainly primitive indigenous races and genetic uplifts such as dolphins.”

The Mongoose alien module makes Aldebaran sound like a great place for adventure, a recently wild area experiencing a dramatic expansion: “A few worlds have been settled for thousands of years but only the coreward sectors of Aldebaran were heavily populated prior to the Solomani Rim War. This changed once Home/Aldebaran was selected as the new capital of the Confederation. Development of the sector has became [sic] a prime engine of new economic growth. The worlds around Home are benefiting from their proximity to the Confederation’s new centre of gravity while settlement of the undeveloped rimward subsectors has been accelerated.”

For semi-canonical data, Steven Eric Schwartz detailed Darsei (Aldebaran 1401) in the article "Bootean Federation," in Imperial Lines 2. Darsei belongs to the titular Confederation member state and is notable as one of the few Confederation worlds that reached TL 15 by 1120.

For Jon Zeigler’s lost Aldebaran project he evidently ignored the dotmap from Solomani and Aslan and redid the whole sector. He referenced several undetailed Aldebaran worlds in various GURPS Traveller New Service bulletins from 1120-1130:

  • Covenant (Aldebaran 0000), a world with a planetary parliament,
  • Daedalus (Aldebaran 0000), home to the pleasant island resort of White Kyros, known to cater to Solomani Party leaders,
  • Europa (Aldebaran 0000), a world struggling with an ongoing civil rebellion in 1121,
  • Euxene (Aldebaran 0000), presumably located in subsector A,
  • Heimdall (Aldebaran 0000), a balkanized world with the breakaway nation-state of Bremagne,
  • Marava (Aldebaran 0000), a hereditary monarchy ruled by a deposed noble family that claims title to the Iridium Throne. Emperor John III ascended in 1119,
  • Monterey (Aldebaran 0000), a system with multiple gas giants near Home,
  • Teilhard (Aldebaran 0000), a "relatively isolated world,” and
  • Twilight (Aldebaran 0912), the homeworld of Marc Chissano, who served as Secretary-General of the Solomani Confederation in the GURPS timeline from 1120 until he was deposed in 1122. The hex location would put this world in Subsector F. The 132-1121 TNS bulletin references a "Star Bridge" subsector, which may refer to F. Twilight was an authoritarian dictatorship ruled by the Chissano family until overthrown by a junta in 1121.
Finally, Paul Drye and Zeigler collaborated on a great little article, "Shuanyun," which appeared in JTAS Online (April 1st, 2003). It details the Shuanyun (Aldebaran 0334) and Taurea (Aldebaran 0532) systems, Taurea Subsector (M), and the nifty Taurean minor race.

Process

For my regenerated Aldebaran, I went through the following steps:

  • Identified all of the systems that correspond to the Solomani and Aslan dotmap, and added the missing Home to hex 1009. The CORE dataset was pretty close, but shifted some stellar positions around in subsector B and missed a world in subsector N.
  • Placed the three lone worlds with canonical positions and UWP data: Home (1009), Darsei (1401), and Willeson (1216).
  • Followed the borders in Solomani and Aslan, which include the Solomani Confederation, the Malorn Union, and the Winston Democracy.
  • Identified the likely position of a few real world stars that are in approximately the right position and distance from Terra, such as Aldebaran.
  • Generated raw planetary data for remaining worlds using GURPS Traveller: Interstellar Wars in order to get a grittier, more frontier feel that still fell within the expected Traveller distribution of habitable worlds. Converted this data to T5.
  • Generated political data using T5, with modifications to starport, population, and tech level as described in Solomani and Aslan. Capped Solomani worlds at TL 14, with the exception of Darsei, which is at TL 15 as described in Imperial Lines 2. Capped non-Confederation worlds at TL 13.
  • Generated the rest of the UWP data using T5 rules, including trade classifications and remarks, Importance, Economic and Cultural Extensions, number of worlds, bases, and traveller zones.
  • Generated stellar data and mainworld placement in the system, climate data, and disposition as satellite or planet based on T5 rules.
  • Placed the 11 semi-canonical GURPS Traveller worlds, finding the next closest world in those situations where the specified position didn’t line up with the Solomani and Aslan dotmap.
  • Established worlds belonging to the Quesada and French Republic member-states. Placed Inerria.
  • Swapped a few of the higher population and tech Confederation mainworlds in the rimward subsectors with lower population and lower tech mainworlds in the coreward subsectors, to better reflect Mongoose Traveller’s depiction of the sector as a wild frontier area undergoing rapid development since the end of the Rim War.
  • Established subsector capitals and world ownership based on T5 guidelines using Importance.
  • Placed the homeworld for the extinct Neozinga minor race, explicitly described in Mongoose Solomani as being in Aldebaran. Placed the homeworld of the Kwaz (also spelled Kvaz), which is unspecified in Mongoose Solomani but assumed to be in Aldebaran because of its connection to the "Red Zone Affair." Left a couple of placeholder homeworlds for unspecified minor races, as the Mongoose book refers to multiple primitive indigenous races in Aldebaran.
  • Seeded a few minor races described or suggested by Mongoose Traveller Solomani, including small populations of uplifted dolphins, selenites, and uplifted apes.
  • Deliberately located military bases, red zones, and military rule on a cluster of low-population Confederation worlds on the frontier border with Neworld Sector. I wonder what is going on there?
  • Named the subsectors without official or semi-official names.

Results

This Google Sheet details the results. The data on the Traveller map differs slightly from this file.

The Traveller Map only supports official 4 digit alliance codes, but I used the following codes in order to identify the worlds belonging to Solomani Confederation member states:

  • MaUn - Malorn Union
  • NaHu - Non-Aligned, Human-dominated
  • SoCo - Solomani Confederation
  • WiDe - Winston Democracy
  • SoBo - Bootean Federation
  • SoQu - Grand United States of Quesada
  • SoFr - Third Reformed French Confederate Republic
The Traveller Map also only accepts standard stellar details, but the attached file has the information in Dalthor notation, which captures considerably more detail. An asterisk indicates the star orbited by the mainworld. Stars within parentheses are in Close Orbit in the Inner System; stars within curly braces are in Near Orbit in the Outer System; stars within square brackets are in Far Orbit. Two stars next to each other without punctuation are a star and a companion in very close orbit.

The subsector names I came up with:
  • A - Euxene
  • B - Aldebaran
  • C - Wovoka
  • D - Firdausi
  • E - Star Bridge
  • F - Sephi Hydra
  • G - Quesada
  • H - Kursa
  • I - The Barrens
  • J - Epsilon Tauri
  • K - Elnath
  • L - République
  • M - Taurea
  • N - Theta Aurigae
  • O - Narmada
  • P – Hesperia

Took a look at you work and looks it good but I was wondering if you had any plans of putting borders for the three members states in addition to the alliance codes. Wonder since I have been think of printing up some maps for the entire Confederation.

That's a good question. Right now Magyar is the only T5SS sector with member-state data. I would like to see the borders myself, but it's not at all clear whether the member states are still canon.
 
Ahem, is this thing on?

As far as I'm concerned, they are... subject to what is known about the member-states.

I've got information on Solomani Rim, Magyar and Alpha Crucis; I've just got to incorporate the data back into the T5SS.

We originally added them in with Magyar intending to see it released, but it wasn't, and the matching data for the other two wasn't added back in after those were released.
 
I just suggest making sure that TLs 9+ are more common among the lower-tech worlds. Low-pop and low-starport places are fine.

I should have added a step to my list that was "adjusted TL upwards for Solomani Confederation worlds." And another pass for all the worlds in the sector might make sense.

The Solomani and Aslan guidelines for Confederation worlds included the following:

  1. Use the "Cluster" column for starports, which results in better starports
  2. +1 to population rolls for sectors adjacent to the Rim
  3. -1 on TL, capped at 15. As S&A is set in 1120-1121, the 1105 cap is 14.
The text describes the results as a lower, but more consistent TL for the Solomani Confederation. Based on this, I expected a narrower range of TL. What I found was a lower range that seemed just as wide as Imperial worlds with all sorts of low TL worlds. This result didn't line up with the backwaters of even Alpha Crucis and the Rim.

There are at least three potential justifications for maintaining some lower TL worlds in Aldebaran:

  1. Sanctaterra, as described in S&A, is a popular agrarian religion in Solomani Space. “Its adherents are fundamentalists who wish to limit the amount of technology in their lives. They typically live on readily habitable worlds with low tech levels.” This could explain low TLs in subsectors A-D
  2. MGT Solomani describes most of the rimward Confederation subsectors as having been only lightly settled until after the Rim War, when the placement of Home spurred a land rush. Presumably there are many resulting worlds that simply haven't had a chance to build up their infrastructure, and as a result have low TL. This could explain low TLs in subsectors E-L.
  3. Some of the worlds beyond the Confederation borders were possibly settled during the Rule of Man and isolated during Long Night, and have remained isolated throughout the Third Imperium period. Your typical weirdo lost worlds. This could explain low TLs in subsectors M-P.
I'll take another look at the TLs of those backwater canonical subsectors to see how Aldebaran stacks up.
 
Confederation TLs

I took a look at the T5 data for sectors with either a large Solomani presence or border areas that were comparable to Aldebaran. This Google Sheet has more information, but here's the summary:

SectorWorldsMin TLAvg TLMax TL
Aldebaran22307.8315
Alpha Crucis289210.6114
Dark Nebula10907.6814
Magyar386210.6714
Solomani Rim88011.0614
Spica14907.9515
Ustral Quadrant5028.3014
Total1,07109.8915

I see a couple of interesting things -- the core Confederation sectors of Magyar, the Solomani Rim, and Alpha Crucis have average TLs of 10.61 to 11.06, while the border sectors have lower average TLs from 7.68 to 8.3.

For me, this pretty much confirms Jame's thought that the TLs were too low. Aldebaran probably should be somewhere between the core and border sectors, with an average TL well north of 9.

One thing I want to take a look at are barren worlds in the T5 data. All my pop 0 worlds got 0 TL -- I think I have a higher proportion of these than the border sectors, and that is dragging down the TLs.
 
I'd love to run your data through the T5 Transmogifier and see how close the results are.

Drop me a message.

And I've been looking at doing the rest of the Solomani Sphere in T5SS...
 
Jon Zeigler evidently worked up an alternative dataset for an abandoned GURPS Traveller: Grand Frontiers supplement, which was to have covered Aldebaran. I contacted Jon a few weeks ago to see if he was interested in reviving that work, but it appears that his draft materials have all been lost. So I decided to roll up my sleeves and take a shot myself.

It looks like he's found some of his files:

https://forum.rpg.net/showthread.php?803007-Traveller-A-pleasant-surprise-Aldebaran-Sector&
 
I know this is an old thread. But Travellermap.com uses both two and four-character allegiance codes for worlds.

I wonder if that's a mistake, for the M1105 Milieu there's only one instance of a two character allegiance code showing up on travellermap, and that appears to be for a single world, "Cenhening", in a distant sector, when selecting for M1105 and Official, InReview or Preserve categories.

And, I just noticed, that's a Official Faraway sector. If you only use (Official || InReview || Preserve) && OTU for M1105 you only get four character allegiance codes.

In the default era for the map I been downloading sectors from, my AI found a bunch of "Zh" allegiances instead of the usual 'ZhDa" type stuff.

Do you download everything or just Official + InReview + UnReviewed OTU? And are you reading allegiances from sector metadata or from the systems directly? Can you give me an example of a 2-char Zh?

Thanks!

It should probably be Unreviewed rather than Official, since it hasn't gone through the T5SS process.
