Aslan Border Clans

The Battle of Taiwaeaa (1056), one of the final engagements of the Chacimu campaign waged by the Solomani Confederation against the border clan Hlawya.

Traditionally, the outer fringes of the Hierate have been populated by wilder small clans. Proud, fiercely independent, and highly aggressive, these border clans (htaraikhau huihaia) occupy a place in the Aslan imagination something like the Cossacks of ancient Terra. Border clans were sometimes employed by larger clans as shock troops or internal security, and fought on both sides of the Purge where they were considered ferocious, uncompromising warriors. Border clans tend to shun the carefully regulated, ritual battles (yerlik) that characterize conflicts of the interior Hierate, preferring instead to engage in total war. While the various border clans tend to be more backward and aggressive than the interior clans, they share few other traits or beliefs. There is no common “border clan” identity, and the term is sometimes applied indiscriminately for any small, combative clan.

The practice of maintaining htaraikhau huihaia on the frontiers stretches back to pre-spaceflight Kusyu, but today only major clans generally have the resources to actively cultivate these assets. Patron clans relocate—occasionally forcibly—particularly aggressive minor clans in the interior to worlds on the edge of their territories. Similarly, exceptionally large and belligerent ihatei bands might be granted frontier lands. In either case, border clans are generally not vassals to a more powerful patron clan, but instead retain an ostensible independence. In exchange for their freedom and territories, the border clans serve as a formidable buffer against encroachment by other clans and alien species.

At its worst the practice is nakedly exploitative: the patron clan provides weaponry but only just enough economic and technological support to ensure the border clan remains dependent; the patron also encourages extreme aggression, xenophobia, and the raiding of neighboring systems. Such activities are often to the ultimate detriment of the border clan. As the frontier expands many of these border clans assimilate or are destroyed, to be replaced by suitable new clans drawn from the interior.

Historically, the Yerlyaruiwo and the Khaukheairl have maintained border clans along the rimward frontier of the Hierate. The Tralyeaeawi and Tlerlearlyo formerly maintained border clans in and around the Human-Aslan Interface, the most infamous of which were certain clans made up of human Aslan, much feared for their unremitting brutality. Cultivating border clans continues apace in the Trans-Rift Colonies, but due to restrictions imposed by the Peace of Ftahalr this practice must be undertaken clandestinely. Both Hrasua and Syoisuis are suspected of covertly supporting several border clans in this region.

One interesting side effect of this tradition is that the border clans often become the face of the Hierate to neighboring alien communities. Consequently, many neighbors have a distorted view of the Hierate, believing the inhabitants to be far more aggressive and violent than they actually are. This perception is a double-edged sword, as it effectively deters both hostilities and friendly trade with the Hierate.

A border clan can be generated using the following modifications to the system in Clans of the Aslan: Holdings are generated using 1D-1, making them either Minor or Single World clans. Age is generated using 1D-3. Aggression and Tradition are generated 1D+4. Tech Level is generated using the Major Vassal column with DM-2.

Oiaous (Dark Nebula 2020, C6518J9-8)

The Hyulreilraw of Oiaous in the Dark Nebula are a representative border clan. Originally located in Reaver’s Deep, they were installed on their homeworld by the Khaukheairl shortly after the Peace of Ftahalr redrew the borders of the Hierate. The Hyulreilraw are a deeply traditionalist clan best known for their garish orange garb, severe interpretations of clan honor, and utter refusal to take prisoners. The Khaukheairl have used Hyulreilraw mercenary units in several recent actions against the Solomani, including punitive raids against Neween in 1102 and Dejeran in 1103. The latter incursion resulted in the massacre of an entire Home Guard garrison at the gates of the Dejeran capital city. When Solomani reinforcements subsequently trapped the Hyulreilraw raiders, the mercenaries refused to surrender and instead fought to the last Aslan, exacting a dear cost to the human defenders.

Clans of the Aslan: Director's Cut

In honor of the recent release of The Aslan Hierate, I thought I’d post a compilation of tweaks to the Clan Generation system featured in Clans of the Aslan. In the course of writing Hierate I put this system through its paces and did find some room for improvement with at least a few elements.

I don’t consider these changes as errata, exactly: the system as published should serve Referees just fine for generating a handful of clans for a subsector, but for sector-wide development the following suggestions should work even better. In general, these tweaks add a little more variability to the various tables without changing the average result too much.

Clan Holdings

Replace the Random Clan Holdings table on page 79 with the following:

Random Clan Holdings
2DMajorMultiworldSingle
World
Minor Major
Vassal
Vassal Minor
Vassal
28650550
38650550
48650550
59750650
69751651

8A752762
9A852762
10A853763
11B954763
12BA54773

These changes are discussed further in Holdings and the Multiworld Clan.

Vassals

Replace the table on page 82 with the following:

Number of Vassals
2DClan Holdings
0–12–456789AB
2000D3-2D3-2D3-12D+12D+42D+4

12D3-1D3D3D3+1D3+22D+12D+84D+176D+15

DM-1 if a minor vassal, vassal, or major vassal clan.

Roll to determine the total number of Vassal clans; divide by 3 and round up to determine number of direct vassals. The remainder will be indirect vassals that owe fealty to one or more of the direct vassals.

These changes are discussed further in Vassal Clans Revisited.

Clan Status

Under the “Clan Status” table of modifiers of page 85, change the modifier for Major Vassal Clan from +2 to +3, and for Vassal Clan from +1 to +2.

All major clans have Status F+, with the top eight clans in the Hierate having Status G, determined by Referee fiat.

Replace the Clan Status table on page 83 with the following:

Clan Status
StatusDescription
0Exohierate clan
1Exohierate clan, outcast or unrecognized Hierate clans
2Unranked Hierate clan
3Unranked Hierate clan
4Unranked Hierate clan
5Unranked Hierate clan
6Hierate clans ranked 1,537–2,048
7Hierate clans ranked 1,025–1,536
8Hierate clans ranked 769–1,024
9Hierate clans ranked 513–768
AHierate clans ranked 257–512
BHierate clans ranked 129–256
CHierate clans ranked 65–128
DHierate clans ranked 49–64
EHierate clans ranked 33–48
FHierate clans ranked 9–32
GTlaukhu clans ranked 1–8

These changes are described in further detail in Clan Status across One Thousand Hierates.

The Aslan Hierate Available on PDF

An artistic depiction of the “Fall of the Oldhalls.” During the Yerlyaruiwo-Tralyeaeawi War, the upstart Hwaiuira clan maneuvered the much more powerful Uawairlew (Oldhall) clan into accepting a ritual war with terms that favored the cunning Hwaiuira. The defeated Uawairlew subsequently relinquished their seat on the Tlaukhu council to the Hwaiuira, who then became known as the Hlyueawi (Cleverman) clan.

The Aslan Hierate, my latest book for Mongoose Traveller, is now available in PDF and pre-order, with hard copies hopefully available by the end of the year. This should be a nice companion piece to Clans of the Aslan and details Hlakhoi sector, a conflict region in the heart of Aslan space.

If Clans was theory, Hierate is practice as I used many of the design systems from the earlier book in developing this latest one. In fact, I have a blog entry over on Planet Mongoose describing the writing of this book.

Hierate was probably my hardest book to write so far but I’m extremely happy with how this came out. I had a chance to work closely on this with Natalie Miller, who did a bang-up job with layout. In many, many instances she was able to transform a nebulous idea into a great-looking illustration or diagram. And amazingly, she was able to make a really sweet map of clan territories in Hlakhoi—something I believed was an Impossible (16+) task, given just the sheer number of clan alliances.
