Politics & Diplomacy (Interstellar Relations)
No information yet available.
Halcyon Sector has a population in excess of of 41.198 billion sophonts. Significant populations of the following sophont species are found within its borders:
- Humaniti (Human races)
- Solomani (Major Race): 33.197 billion (80.58% of the population), descended from human refugees fleeing the Destruction of Terra. They refer to themselves as Terrans.
- Other Non-Human Races:
- Esaran: 3.748 billion (9.09% of the population), largely concentrated within the Esaran Cultural Area.
- Hoppers: a sophont species native to Fedan in Far Home Sector. An estimated 2.4 billion "Outer" Hoppers (5.82% of the population) inhabit human-controlled space within Halcyon Sector, most typically forming insular self-sufficient communities within established urban areas. A significant Hopper population, many of whom are refugees from the Unity of Sed, resides within the campus of the University of Selasia.
- Kithenka: 200 million (0.48% of the population), almost entirely concentrated on Feluchar.
- Loons: 20 million (0.05% of the population), entirely concentrated on Paradise.
- Meroquan: 70 million (0.18% of the population), largely concentrated on Fieral.
- Oquo: 63 million (0.16% of the population), entirely confined to Quarin.
- Orokath: 500 million (1.21% of the population), entirely concentrated on Feluchar.
- Temelik: up to 100,000 (0.0025% of the population)
- Treehangers: 1 billion (2.43% of the population), entirely concentrated on Sarunt.
The following languages are among the most commonly spoken within Halcyon sector:
- Fleet Anglic. The language of the First Confederation and the Last Armada. It is no longer widely spoken outside of academic circles but is the root tongue of a number of other languages:
- Anglish The language of the Bright Conclave and the Enlightened. A direct descendant of Fleet Anglic, widely spoken throughout the Distant Fringe. Most people know a few words and phrases of Anglish.
- Coran. The language of the Unity of Sed and The Last Line. The language of the Corolian Jurisdicture.
- Padori. A language of Far Home Sector. It is most common in the rimward-trailing quadrant of Halcyon Sector, particularly around the Wolfs Tail Star Lane.
- Teramil. The language of the High Senate and the Nist cluster. The language of the Scybrian Polyarchy.
- Esar. The language of the Esaran.
- Jitsathu. The language of the Yimin Jiti and a common language in the rimward half of Halcyon Sector.
The capitals of polities located within Halcyon Sector are:
- Jesel: the capital of The Last Line.
- Sedulan: the capital of the Unity of Sed.
- Entremis: the capital of the Dependent Worlds.
- Denirad: the capital of the High Senate.
- Rasand: the capital of the Esaran Cultural Area.
- Blass: the capital of the Enlightened.
- Narit: the capital of the Yimin Jiti.
- Selasia: the capital of the Bright Conclave.
At the current time (5600AD) Halcyon Sector contains six interstellar polities and four smaller territories.
- The Bright Conclave is a relatively isolated feudal technocracy descended from the Bright Expansion Development Organisation. It is a center of learning and study and is a bastion of knowledge. It is ruled by an academic elite drawn from the University of Selasia, who make decisions for the good of the state and its citizens based primarily on the technical merits and implications of the proposition. They are supported by an extensive but efficient bureaucracy. As a rule life is good within the Conclave, with its citizens enjoying the highest standards of living and broadest personal freedoms within the Distant Fringe. A small but vocal Mantlerist movement exists within the Bright Conclave.
- The Enlightened is a shadowy state, nominally a democratic confederation of worlds but with many decisions and policies being made behind closed doors and achieved through dubious arrangements and "understandings" between interested parties. Its heritage draws strongly on corsair traditions, and many of its fundamental laws and rulings draw from a formalised "pirate code" underpinned by principles of fairness, equality, and collective possession of "shares in a venture". There is some evidence to suggest that interests within the state actively support corsair and pirate activity within the Distant Fringe.
- The High Senate is a representative democracy with a system of government open to public scrutiny. It emerged from the heartlands of the Scybrian Polyarchy, an aggressive and militaristic state that was the major losing power in the Scybrian Wars. Even after more than a century, the worlds of the High Senate still bear the scars of that conflict. It harbors a huge amount of cultural shame and remorse stemming from its conduct during the wars: the population is overwhelmingly pacifistic and isolationist. The government is pragmatic, however, and understands the need to act in its own interests and in the interests of its allies. It is engaged in a number of covert campaigns against the continued expansion of the Unity of Sed. The High Senate is a major commercial center and lies on the Runners Edge and Scybrian Run Star Lane.
- The Last Line is a fragment of the former Corolian Jurisdicture: it is austere, militaristic and intensely paranoid and is run by an overloaded and inefficient civil service bureaucracy. Many commodities are in short supply and there is a burgeoning black market. It is governed by the Interim Assembly, made up of former high ranking officials of the Jurisdicture. A relatively large proportion of the population are refugees fleeing the Unity of Sed. The state is also home to "refugee corporations", businesses who have fled the violent mayhem with much of their machinery and equipment. Psionic shielding is routinely emplaced in buildings and vehicles and worn as personal protection. Conditions throughout the Last Line are uniformly poor, with many lacking access to even the most basic infrastructure. The military are everywhere.
- The Unity of Sed occupies the heartland of the former Corolian Jurisdicture. It is in the grip of a cabal of Arvanite fanatics and zealots bent on spreading their bizarre philosophy and views across the Distant Fringe. They are able to interpret the teachings of Sed Arvan and use them to motivate and command the population and steer the polity towards their own goals. While the denizens of the Unity seem enthralled by the bizarre New Order, their state has become a place of focused anarchy, routine brutality and social decay. Norms vary from day to day and proclamations and declarations may change the status quo in moments: it is unclear how it maintains any form of internal cohesion or strategic direction. The Unity is capable of converting otherwise reasonable and rational individuals to its beliefs, vastly swelling its numbers. More rapid expansion has been hampered by internal bickering and by resistance from the worlds it has occupied. Local strongmen and Arvanite militias hold considerable power.
- The Unity of Sed persecutes non-human sophonts.
- The Unity of Sed routinely utilises psionic abilities.
- The Dependent Worlds are controlled by the Unity of Sed. They are an isolated group of systems and a former autonomous region of the Corolian Jurisdicture. A huge percentage of the domestic population have become Arvanites, despite having formerly expressed intense hostility to its tenets and beliefs. As it descended into a state of anarchy the Dependent Worlds voluntarily declared their allegiance to the Unity of Sed. The fragile domestic situation continues to devolve and civil norms and routine processes are breaking down. Local strongmen backed by fanatical Arvanite militias have emerged and maintain their particular versions of law and order.
- The Liberated Stars are formerly neutral systems lying along the strategically important Jubb-Duseb Corridor and Runners Edge Star Lane. The worlds have been absorbed by the Unity of Sed and are gradually descending into chaos. Radical Arvanite movements backed by heavily armed militias are emerging, enforcing their own version of law and order.
- The Yimin Jiti are a withdrawn, passive, and outwardly maintain an appearance of a low TL.
- The Yimin Jiti routinely utilise psionic abilities.
- The Esaran Cultural Area is a broad region dominated by the Esaran, a technologically advanced sophont species: Esaran are the dominant species on its worlds. Oquo, relatively primitive sophonts native to Quarin, make up around 1.65% of the population, while resident humans make up around 0.013%. The worlds of the Cultural Area are overseen and administered by the Esaran. They are efficient and rather humorless and can come across as aloof and arrogant. The Cultural Area adopts a stance of strict armed neutrality, though the overt hostility displayed towards them by the Unity of Sed has caused alarm. The Rasand Link Star Lane, a major trade route, runs through the heart of the Cultural Area.
- The Retreat is a multi-faith religious community that has been a haven of peace and tranquility for almost a millennia. Different regions of its member worlds are given over to different faiths. Each of the faiths sends representatives to the Pantheon, an extensive complex of architecturally significant buildings considered to be neutral ground, to consider issues and set policies. The communities are supported by extensive bureaucracies and defended by hand-picked and specially trained Guards. The worlds of The Retreat have the largest burial grounds within the Distant Fringe.
The spinward-coreward region has a long and complex history but is in turmoil. The old Corolian Jurisdicture has fallen to the malignant Arvanite movement and become the Unity of Sed.
- The Last Line
- The anarchic Unity of Sed continues its expansion to trailing and rimward, casting its gaze over the High Senate and the Nist Cluster. Local strongmen have seized control of entire regions within the state and planetary governments are little more than puppet regimes, slavishly answering to outside forces. Arvanite militias patrol throughout settled areas, enforcing their own interpretations of Arvanite teachings. Waves of poorly equipped but fanatical raiders, often aboard captured ships and led by demented petty demagogues, pour out of Unity space and cause havoc within the worlds of the Sector. Small cadres of resistance exist but are few and far between. Outsiders are not welcome at all and those who do intrude face the weight of the Unity's considerable military and naval forces. There is no reasoning, no negotiating with the Unity of Sed, though individual leaders may be more open to approach.
- The Unity of Sed routinely utilises psionic abilities.
- The isolated Dependent Worlds are completely under the sway of the Unity of Sed. Arvanite militias have begun to form and patrol with the aim of maintaining social order and cohesion: they frequently come into conflict with one another. The Dependent Worlds appear to have begun a slow descent into anarchy and madness.
- The Liberated Stars have fallen to the Unity of Sed. Previously hostile to that state, a huge percentage of the population have come to support the new regime and converted to its Arvanite beliefs. Mass unrest is increasing and the domestic situation is chaotic: Arvanite militias have been invited to its worlds to help maintain order.
- The Nist Cluster, always considered the junior partner in the Scybrian Polyarchy and the soft underbelly of that state, has enjoyed independence for more than a century. It shares a language, culture and heritage with the High Senate but has no intention of surrendering its neutrality. The Unity of Sed has made no secret of its intentions to "convert" the populations of the cluster and bring them into its fold.
- The Jubb-Duseb Corridor, a vital bridge between the Nist Cluster and the High Senate, has been subsumed by the Liberated Stars: its formerly neutral worlds have fallen under the sway of the Unity of Sed. Transit along it has been seriously affected by the unfolding situations on its component worlds. Conditions are chaotic.
- The spinward end of the Runners Edge Star Lane is considered to be extremely dangerous and regular commercial operations along it have been suspended: a huge percentage of ships travelling into the Unity of Sed fail to return. Smugglers and commercial scouts are among the few vessels willing to take the risk. Conditions along the Star Lane are anarchic.
The coreward-trailing region of Halcyon Sector has been settled for millennia and has a rich and complex history. Laden merchant vessels turn handsome profits trading between its prosperous worlds.
- The High Senate, balancing public support and scrutiny against state necessity, conducts covert operations to support its interests and those of its allies. It is actively involved in resisting the expansion of the Unity of Sed, sending highly trained and well-equipped military units and naval forces to carry out missions and operations, generally under the flags of mercenary organisations. It actively patrols the Scybrian Run and Runners Edge Star Lanes, targeting smugglers and traffickers and preventing piracy.
- The Rissa Gateway remains a major commercial center on the Scybrian Run Star Lane. It has reputation as a hotbed of intrigue and espionage, dating back to the time of the Scybrian Wars and its key strategic position between the warring Firstworlds and Scybrian Polyarchy.
- The Scybrian Run Star Lane is the major trade artery of the Distant Fringe, seeing huge volumes of traffic between the High Senate and the Firstworlds, in Far Home Sector. It is patrolled by naval units from both the High Senate and Firstworlds. Both navies observe traditional salutes – generally involving firing "warning shots" – when they encounter one another. These traditions date from the Scybrian Wars.
- The Runners Edge Star Lane is effectively closed to trade. Conditions along its spinward end are chaotic and a significant percentage of the vessels that venture along it fail to return. Those few ships that do reappear tell tales of insurrection and mutiny among the crew, often culminating in the loyal survivors staging a daring escape. The mutineers are said to adopt radical Arvanite views and philosophies and exhibit bizarre behaviors.
The rimward-trailing regions of Halcyon Sector are a quiet and bucolic backwater.
- The Retreat lies on the Pessent Spur Star Lane. Missionaries, religious figures and envoys bearing edicts travel between its worlds and the greater Distant Fringe, and there is a stream of funerary traffic to and from its worlds. Religious holidays are scrupulously observed. Casual travel within its borders is heavily restricted and vessels are assigned a sanctioned "Spiritual Guide" for the duration of their time within its borders. Guides must be consulted on all major issues and their rulings are considered final.
