The Supreme Duchy (of Mozgovia)
Although the smallest of the Tungusk Sector’s sub-sectors, the Supreme Duchy represents the fulcrum upon which the entire sector balances. Sitting at the nexus point of numerous intra- and inter-sector Warp routes, its planets are centres of heavy industry and mass trade, manufacturing everything from cogitators to super-heavy vehicles and shipping them not only across the sector, but to far-flung battlefronts throughout the Galaxy. Its evolution from Great Crusade-era naval logistics outpost to centre of sector governance is owed almost entirely to House Ivanova, who carved the Duchy from the surrounding fractious sub-sectors, exploiting their resultant position as the most unified and militaristic of noble families to cement their de jure status as Sector Governor into a military and political fact. Under their singular (some might say megalomaniacal) rulership, the Duchy has come to represent not only a trade hub, but the nerve centre for the entire sector, containing the regional seats of power for the Ecclesiarchy and Administratum.
The Hanzar League
Established largely by the Mechanicus and their supporters, whose Combined Explorator Fleet (Designate: Hanzar) covered the flanks of the Great Crusade’s main thrust into the sector, the Hanzar League has earned a notorious (albeit not entirely undeserved) reputation as a hotbed of discontent and even outright heresy. During the Horus Heresy, many of its nobles, ambitious to establish their dominance over the fledging sector, joined forces with the traitor Legions to overthrow the sector’s White Scars guardians. As a result, the League was subjected to some of the greatest purges during the Grand Pogrom, but doubts still remain as to the true loyalties of its surviving potentates, as do resentments over the damage inflicted to the sub-sector’s industry and infrastructure by loyalist forces. However, the long millennia have afforded the League an opportunity to rebuild, especially with the continued support of the sub-sector’s heavy Mechanicus presence.
The Republik de Novogyr
During the early years of the Tungusk Sector’s settlement, those Humans dispatched to colonise the initial planets found themselves facing an uphill struggle. While the White Scars were far from the worst Legion to work alongside, they were altogether more concerned with the hunt offered by the sector’s xenos raiders, while their Mechanicus attaches were not even second-rate, as the Hanzar Explorator Fleet boasted the priesthood’s finest. As a result, the Novogyr colonies were forced to cooperate to a far greater degree than even common Imperial planets must, its various potentates joining together into a so-called ‘Republik’ (admittedly, one where power determined representation) to ensure the sub-sector was governed according to a utilitarian necessity: the greatest good for the greatest number. However, this collaborated turned to chaos when the Horus Heresy erupted and the Republik found itself fracturing amongst loyalists and traitors, with billions of citizens dying as the complex network of trade in foodstuffs, materials, protection and raw energy collapsed. To this day the Republik is much diminished, with territories lost to the Duchy and Boyarchy, its utilitarian collective reduced to a region council, and its influence across the sector little more than parochial.
Originally a frontier province of the Tungusk Sector before the Groznost Crusade established the vast Voivodates, the sub-sector of Tvir-Kosmostra was a curious mixture of self-reliance and dependence upon the Imperium (embodied, respectively, by its two greatest settlements from which it derives its name). Both elements, however, declared themselves overwhelmingly loyalist during the Horus Heresy, and were exacting (some may argue too exacting) in their prosecution of perceived treacheries and heresies during the subsequent Grand Pogrom. Unsurprisingly, the Ecclesiarchy found fertile ground for their faith in both the righteously self-reliant and those who looked to the Imperium for their continued survival, and the sub-sector rapidly became a bastion of zealotry against the darkness of uncolonised space beyond. However, after the establishment of the Voivodates, Tvir-Kosmostra found itself in the highly favourable position of acting as an intermediary between the old wealth of the established sector and the new riches of the Voivodates, and with prudent politicking its potentates found themselves acting as the gatekeepers between both sides of the sector, and enjoying the riches that sprung forth from that position.
The Boyarchy of Lith
The oldest sub-sector of the Tungusk Sector, the Boyarchy of Lith was the first area of space seized from xenos forces – primarily the Yagai – by the Great Crusade. Its settlers were considered some of Humanity’s finest, and paragons of the Emperor’s idealised vision for their future: strong, resourceful, self-reliant and sceptical. The Boyarchs, established under the Great Khan himself as trusted Human guardians of the newly seized worlds, were fiercely militaristic, proud to a fault and ready to defend the Imperium’s holdings to the last man. While some resentful Boyarchs turned against the Imperium during the Horus Heresy, many remained loyal and were quick to strike down their traitor brethren; but it was during the Grand Pogrom, and later religious upheavals, that the Boyarchy truly suffered, for its roots remained within the Emperor’s secular aspirations for Humanity, admittedly marred by an overgrowth, dark mythology surrounding the Yagai and their multifarious spectral horrors. Nevertheless, the Boyarchy has remained a major power-player: its planets retain great, albeit slowly dwindling, mineral wealth, and it boasts some of the most ferocious military units in a sector already notorious for the zeal of its warriors.
Established by the Groznost Crusade that expanded the sector’s influence, the Voivodates are a vast and disparate sub-sector only truly united by a sense of exclusion from the ‘old sector’. While many of the Voivodes can still trace their lineages back to the ‘old sector’, they are nevertheless viewed as a lower order of nobility – martial governors and garrison-lords of wild, frontier space, rather than truly elevated rulers of civilised, sophisticated planets. The distinction is not entirely false, for the Voivodates are largely a squabbling pit of neighbourly disputes, ancient rivalries and perceived slights, held together only by the occasional inter-marriage, shared enmities, and a common grudge against those who think themselves the Voivodes’ betters. As a result, the sub-sector is not as heavily developed as its Great Crusade-era counterparts: while individual planets, and some of the more established systems, can be as sophisticated and productive as those in the Supreme Duchy or League, overall the sub-sector is characterised by a sense of ‘untapped potential’ – not helped by the Voivodes’ insistence on maintaining the fiercely unpopular and inefficient system of serfdom.
The Tartorsky Hinterlands
A series of Warp storms and spatial anomalies at the far edge of the Tungusk Sector, the Hinterlands represent the edge of Imperial rule, and are home to various displaced Xenos empires, heretical organisations driven from the Imperium, and worse creatures besides.
