Firstly I would like to clarify Vjun's population. I would like it to stand at around 9-11,000 across the whole world, mostly living in isolated farmsteads, causing the difficulty of holding a census, very little of the Vjun population would be urbanized, most living out on the wide holdings of the Vjunite nobles.

The population would be divided as follows:

The Nobility, making up around 5% of the population this group hold the hereditary power vested in them since time immemorial. Their power has been somewhat abraded by the massive wave of deaths from the Vjunite Plague, leaving many of their tenancies vacant, their children dead and their number ageing. Many of the remainder of this group have consolidated their position by leaving Vjun and marrying the heads of rich (but often not aristocratic) families in order to preserve their genetic stock from extinction. In recent years they have done what all aristocrats do in modern times, trimmed sails and survived.

The Serfs, the serfs are unfree tenants of the nobility (around 85% of the populace). These individuals vary considerably in wealth and status, some holding wide and fertile lands (for Vjun) and having wealth equivalent to the nobles, some have been able to rent the feudal rights for whole estates from absentee nobles, and been able to lord it over the lords tenants as if they were the lord himself. Most, however, are considerably less lucky, eking out a meagre existence from the hard soil of the Vjunite upcountries, or fishing for the horrific creatures which live in Vjun's poison seas. While their existence is often poor, they have benefitted from rents dropping after the plague, leading to more farming. Vjunite serfs may not leave their lord's land for more than a day without permission. Traditionally they may acquire their freedom by living in a town for a year and a day, however, this means forfeiture of all their land, property and family. Thus it is that few serfs leave their lands and become freemen.

Freemen make up the third group in Vjun Society, freemen are not bound to land or lords by feudal ties and often work in trades such as weaving or metallurgy. Freemen as a group vary considerably in wealth also, with some holding wide lands or large companies, however, most are small craftsmen and in some cases labourers. The poorest freemen may find themselves worse off then if they were serfs and in some cases accept feudal tenancies in order to not starve to death. The freemen were the worst hit group in the Vjunite plague due to almost exclusively living in densely populated communities. Freemen, despite a lack of de jure power hold much de facto power, as they run much of what remains of the Vjun state on a day to day basis thanks to the apathy or absenteeism common in the populace.

Vjun is ruled by the nobles, but legislated for by the Parliament of Vjun, composed of 49 members, around 30 representing the nobles and 29 representing the freemen.

Major population centres on Vjun
Bitter End - population 800
The Vale of Horrors - population 540
Drudgetown - population 300
Bast Castle - a small Vjunite shanty community is nearby, featuring a bar and also the living place for menial cleaning personnel, catering etc for Bast Castle's Barracks.

Largely Abandoned population centres
Berrocs Hill, population 1
Sludge - abandoned
Grim Keep - populated by the Count Zahlung's Household FIII droids which fiercely guard the forbidding fortified manor. Count Zahlung passed away during the plague and no heir has claimed his manor.

This fleet would represent a hang over from the old Vjunite Armada, having been around for decades and having been financed by the long dead much larger Vjunite population. A dozen more assorted vessels of similar size would be landed outside of Bitter End, having been landed due to the Inability of the Vjun population to crew them after the plague. These landed vessels would be inoperative due to being landed for a pair of decades in the acidic Vjun environment, however, They would still be a useful source for parts..

The ships would be crewed largely by freemen from families in Bitter End, it being their hereditary right to crew the fleet after the Concord of Darkness, which held that the serfs of a noble may not crew capital ships (after the infamous orbital bombardment of Contwaraberg by the Viscount Malreux's cruiser). Nobles may however hold the captaincy of these ships, but these are usually just feudal titles and in practice their freemen captains actually crew them, while the noble who holds the hereditary captaincy pays for the vessels upkeep.

For example, Bernard Oriel is hereditary captain of the "Misery", a CR70 corvette which has been mothballed for the last three decades due to the cost of keeping her space worthy not being worth the prestige.

1 Consular-class (Militarised clone wars variant)
1 Corellian Star Shuttle - Outfitted with two ion cannon turrets and four quad laser turrets.
2x Gozanti-class Cruisers
12x Cloakshape Fighters
6x Z95 Headhunters
1 Type I Light Duty Space Defense Platform - since armourment isn't stated I'd like it to be armed with 4 turbo laser turrets and 8 quad lasers.
200x Space Mines (scattered around in high orbit and hyperspace jump points), these would be divided into the following
50x Defender ion mine, 50x Mine Type A, 50x Mine Type B, 50x Mine Type C. Only 4 would ever be able to target a single vessel.

For ground forces, there is no organised Vjun Army, militias exist for population centres and outlying communities, while the nobles all have their own retinues of household troopers and droids. All Vjun noble residences are equipped to be defended in a siege, thanks to the rough and tumble small wars common on Vjun a century ago.

These forces specifically do not include Imperial Forces (at Bast Castle, Vjun Rehabilitation Centre, &c).
