Proposed Revisions to Staihaia'yo Sector

The high-population, industrial world of Qyarn (DARK 1420 D5219BB-8), homeworld of the extrahierate Tyesourla clan. The Tyesourla were expulsed from Hierate space during the Cultural Purge for having adopted too many Human practices.

I’ll pause briefly from my deep dive into the Aslan Hierate to report that many of my suggested revisions to Dark Nebula and Magyar sectors have been reviewed and incorporated into the Traveller Map. Many thanks to all the folks who have emailed or commented on my proposals, and to Geir Lanesskog, Thomas Jones-Low, and Joshua Bell from the T5 Second Survey team. It’s been nice to see these tweaks go live.

Since I’m looking at Traveller Map data this week, I might as well circle back to Staihaia’yo, the Aslan Hierate region located two sectors spinward of Dark Nebula. As mentioned a few weeks ago, I discovered a serious problem in the Staihaia’yo data currently up on Traveller Map.

Staihaia’yo was designed by Marc Miller and partially detailed in Atlas of the Imperium (1984). The History of the Imperium Working Group (HIWG) subsequently generated additional sector details, which are hosted at Ocean of Storms. The T5SS project later reviewed and updated the HIWG data to Traveller⁵ standards.

However, when I was analyzing Hierate data I discovered that the HIWG data contained a serious flaw: the sector data only uses two different Aslan government codes: G (small facility) and L (major clan control). The T5SS conversion partially masked this problem, but the resulting allegiance data are badly skewed, resulting in an inordinately high number of Tlaukhu bloc worlds—among other anomalies.

Before making any recommendations, I went back to see what had been previously written about Staihaia’yo. As it turns out, very little canonical data exists beyond AotI. MT Solomani and Aslan (1991) groups this sector as part of the Hierate’s “Central Region,” noting that “Syoisuis clan silently dominates Staihaia’yo, the Yelsafeih Main in particular” and adding that “Staihaia’yo sector, adjacent to the Ancestral Worlds, has always been one of the most politically stable areas in Aslan space.” (48). In MgT Pirates of Drinax (2017), Eafoarei (1821) is the headquarters of the Iyalil corporation (45).

As an aside, the “Yelsafeih Main” is most likely the 105-world main that sprawls across the heart of the sector, and includes the important, high-population worlds of Eatlaihiyia (1638), Aokhalisi (1734), Styehkiloa (1820), Eafoarei (1821), and Alaoa (2228).

I regenerated the government and allegiance codes for the entire sector, making sure that the allegiances matched the base codes from AotI. I then massaged the allegiance data to make sure that the Syoisuis bloc (AsT2) and Tlaukhu Vassal (AsTv) codes were well represented. I revised the ownership data for all worlds with the government code 6.

Staihaia’yo, like the other Hierate sectors detailed in AotI, has a low number of Tlaukhu and clan bases. I retained all of the AotI bases and regenerated data for the “empty” systems, resulting in a base distribution more in line with CT Aslan worldgen. This occasionally required adjustments to Importance and the Economic and Cultural extensions.

I found one additional problem with the Staihaia’yo data: Iylei (0133). Atlas of the Imperium names this world, meaning it has a population of 9 or A. AoI also notes the presence of a class C starport, that the mainworld is a terrestrial planet with water, and that the system contains a gas giant. For whatever reason, the data entry in the original file gives a UWP of “C,” just C, nothing else. This was not caught during the T5SS review, which rendered the world as “C000000-0,” which ended up getting converted to “E000000-0,” and Allegiance “AsXX.” I regenerated the UWP from scratch to result in a new UWP of C657A7A-B and Allegiance “AsSc.” Importance of { 2 }, Economic Extension of (C99+1), Cultural Extension of [AC5B], and a PBG of 114.

For this pass I did not review the stellar data, although Staihaia’yo appears to have an inordinate number of giant and larger stars as well as white dwarfs. I also did not add Traveller⁵ climate or orbital details. Perhaps some day… In the meantime, here are my proposed revisions: Staihaia‘yo sector. Shaded cells indicate changes from the current Traveller Map data.
