Third Imperium

(0 to Present): The Third Imperium itself is a far-flung empire of 281 subsectors and over 11,000 worlds.

• The Imperium is also called the Third Imperium.
• It was founded in 0 by Cleon Zhunastu from the Sylean Federation in what is now Core Sector.
• The Imperium grew swiftly during the pacification campaigns and more slowly thereafter until stability was reached in the 600’s, by which time the Imperium had absorbed much of the territory of the First and Second Imperiums.
• It is also known as the Ziru Sirkaa. Please note the Vilani double -aa ending to contrast it from the First Imperium, which was known as the Ziru Sirka with a single -a ending.
• Please see Emperors of the Third Imperium, Imperial Cultural Region, Imperial Moot and Imperial Nobility for related information:

Astronavigational Codes

A wide variety of astronavigational codes have been used within and without the Imperium over its history. At least two major surveys by the IISS, the First Survey and Second Survey have helped to evolve this system.

Cultural Region Codes

Some parts of the Third Imperium have divergent cultures from the mainstream sensibilities of the Imperium and it has become expedient to develop a federalized system of Imperial Cultural Regions to better meet the needs of these divergent regions. Some of these regions hold official imprimatur from the Emperor while others hold a less official status:

Description (Specifications)

The Imperium is the focal point of history within Charted Space.

• As it rises and falls, so does interstellar civilization... for better or worse.
• It is a powerful aggregate super-polity, supra-polity, a hyperpower, and as it goes, so does the greater state of war and peace amongst the Major Races.
• Some conjecture that the Imperium itself is the results of Ancients social engineering, a venerated Hiver manipulation, or something else. Noone really knows if the Imperium arose on its own bootstraps or as the result of mysterious outside powers.
• Whatever it may be, the Imperium is the 800-pound gorilla in the room and interstellar diplomacy is largely focused around the foibles and tribulations of this single supra-polity. All others rank behind it.

Imperial Overview

The Imperium is a series of consecutive galactic empires reaching back into recorded interstellar history.

A. Goals: 1105

The preamble of the Warrant of Restoration of the Imperium reads:

The worlds of the universe lie separated by the vastness of space, each alone, and dependent upon its own resources. In the past, a greater community of worlds has existed, promoting a greater good for all its members, and for all those who have interacted with it. The time has now come to reestablish that greater community.

On the foundations of the past, in order to promote:

Safe travel among the stars, the exploration of worlds circling those stars, the pursuit of knowledge, mutually profitable trade and commerce, the active exchange of information and tech the individual pursuit of personal betterment, and the collective pursuit of community good, we hereby reestablish the Grand Empire of the Stars.

Significant populations of the following sophont races reside within this polity:

Imperial Sophont Demographics (Populations 10+ billion)

Race	Population	Type	Remarks
Humaniti	015 trillion	Major Race (Various) Imperial Man	Humaniti is the dominant species on the many thousands of systems and worlds within the Third Imperium and while most humans are of Solomani, Vilani, or mixed ancestry, literally dozens of other races and sub-species of humans exist: Minor Human Races, Human Chimerae, Variant Races, ethnic groups, and nearly every other possibility imaginable. Humans are a prolific species and can be found in large numbers throughout vast tracts of both the Third Imperium and Charted Space.
Suerrat	359 billion	Minor Human Race	The Suerrat are a prolific race of hairy humans with atavistic (ape-like) features and a powerful, well-developed space empire prior to being conquered by the Vilani. Their great numbers, wealth, and prosperity still make them a powerful force within the Imperium.
Lancians	235 billion	Minor Human Race	The Lancia or Lancians are a minor human race conquered by the Vilani whose culture has long been repressed. Other than their background and culture, they physically resemble baseline genetic humans in almost every way.
Vegans	155 billion	Non-Human Race	The Vegans are a strange human-like race of arid, low-gravity, near-vacuum desert-dwellers. Their communal culture with its distinctive tuhuirs has long baffled human observers. Their society and space empire has long been a crossroads and pawn between larger major races.
Syleans	119 billion	Minor Human Race	The Syleans are genetic humans with a powerful spirit and ambition. Their cultural achievements form a solid cornerstone of the Imperium and one of their own was reputed to be the founder of the Third Imperium. Cleon I has been reported of Solomani-Vilani ancestry, while others record his heritage as pure Sylean. The religion, philosophy, and trade instincts of the Syleans are widely considered second to none, while maintaining a mysterious spiritual aspect that few non-Syleans ever seem to fully grasp.
Luriani/Roryniar	104 billion	Minor Human Race	The Luriani are an enigmatic race of humans, adapted to a semi-aquatic life. Their flexible culture has allowed them to prosper, even while under foreign yokes. Some attribute it to luck or serendipity, but the Luriani know better.
Kaggushus	092 billion	Minor Human Race	The Kaggushus are powerful, genetically-engineered humans, with a long record of ground combat prowess. Their homeworld has long played an important role in Imperial history and their culture has long been repressed.
Sigka	090 billion	Non-Human Race	The Sigka are an aquatic minor race known for their wide-ranging trade missions and advanced technological prowess. As an aquatic proto-species, they were known for great piscinoid aggregates that shoaled and schooled together and their society cooperates and collaborates with each other in ways that other species can only marvel at...
Darmine	076 billion	Minor Human Race	The Darmine are a minor human race, which has little variance from the human genetic baseline including interbreeding capability. Their culture has long been rebellious and has ever since been tracked by the Imperial authorities.
Aslan	073 billion	Major Race Imperial Aslan	The Aslan are a young and powerful race of felinoid-like sophonts, united in spirit, but not in temporal power. Their often quarreling empire, the Aslan Hierate lies rimward and many Aslan have settled into the Imperium as refugees and exiles with a long and proud record of dedicated and loyal service.
Lurent	070 billion	Non-Human Race	The Lurent are a mysterious, nomadic species with a unique planetoid starship design, a penchant for trading, and a wanderlust second to none. Few know much about the Lurent and they like it that way.
Geonee	065 billion	Minor Human Race	Shorter dwarf-like humans who developed on a heavy gravity, geologically unstable world, which gave them incredible strength and a powerful penchant for taking risks. Their space empire was developing when the Vilani conquered them. Geonee society has always had a rebellious streak as well as a number of well-kept secrets.
Bruhre	060 billion	Non-Human Race	The Bruhre are massive hexapods accustomed to a sulfur-tainted atmosphere and an exotic biochemistry, largely incompatible with mainstream Humaniti and sophontdom. Their culture is extremely complex, and intolerant of outside ways. However, they have keen scientific and philosophical insights that still motivate researchers to overcome their intolerance to learn their insights despite being isolated from mainstream Imperial culture...
Selenites	060 billion	Variant Human Race	The Selenites are human beings, geneered to survive in the microgravities of space habitats. They have experienced explosive population growth and their numbers now make them a force to contend with.
Llyrnians	050 billion	Non-Human Race	The Llyrians or "Devils" are a strange, trisymmetrical, digging species adopted by and allied to the Geonee. Their zero-G combat aptitude make them some of the most capable ship-to-ship fighters ever known.
Vargr	042 billion	Major Race Imperial Vargr	The Vargr are an enormously adaptive race, capable of fitting in anywhere. As a variant race, they have some racial insecurities, but one of their biggest concerns is whether the Third Imperium will ever fully integrate them into their society.
Answerin	040 billion	Minor Human Race	The Answerin are baseline humans with little genetic variation, while their culture sets them greatly aside. Their powerful psychological sciences help them conquer fear in unparalleled ways. They are fatalistic in one aspect and supremely self-confident in others. Their service as mental health specialists and, oddly enough, fearless mercenaries is in high demand throughout Charted Space.
S'mrii	028 billion	Non-Human Race	The S'mrii are an enigmatic alien race of insectile centauroids with a long history of loyal and dedicated service to the Imperium. The history of their ancient culture is studded with great tragedies and even greater technological achievements.
Nenlat	024 billion	Non-Human Race	The Nenlat are a strange trisymmetrical race of amphibianoids known for their strong tastes for adventure and exploration. Their technological aptitude makes them commonplace on tramp freighters, interface starships, and exploration teams throughout Charted Space.
Dolphins	020 billion	Non-Human Race	Dolphins, an aquatic species and variant race from Terra, were brought by the Solomani to interstellar space. They have prospered ever since and their keen astrogational skills are in high demand.
Ziadd	017 billion	Minor Human Race	The Ziadd are a minor human race with atavistic Neanderthal-like characteristics. Their dynamic culture and keen mercantile instincts have made them famous throughout the Imperium.
Llellewyloly	015 billion	Non-Human Race	The "Dandies" are a finicky bunch of non-humanoid sophonts with a near-unique biology, full of complex social rules that make it hard for outsiders to join their society. Their unique outlook allows them to see many problems "outside of the box", which has led to some remarkable technological innovations. Much of their society is still blanketed in mystery despite centuries of interaction with Humaniti.
Chirpers	015 billion	Non-Human Race	Chirpers are a simple apolitical race of pet-like sophonts that some suspect are proto-sophonts, primitive versions of the Droyne, or possibly even related to the Ancients. They might be simple babes in the woods or they could be a species far more devious...
Bwaps	010 billion	Non-Human Race	The Bwaps are an amphibious, newt-like species dependent on moist air humidity, who are an ubiquitous part of nearly every institution, bureaucracy, and paperwork processing organization throughout the greater Third Imperium. Their regenerative automy ability is well-known (...they can regenerate entire limbs), but their secret experiments into Psychohistory are only rumored at. The mild unassuming image of a Bwap functionary is portrayed throughout the popular media, but what other secrets do these master bookkeepers hold?
Kirissukyoya	010 billion	Non-Human Race	The Kirissukyoya a strange trisymmetrical race of starfaring merchants. Their race was known for high quality merchandise throughout Deneb Sector until internal differences led to a global war which devastated Kiri civilization. They are still re-learning and re-gaining their former glories after a devastating conflict in which the Droyne mysteriously intervened. Observers still ponder why the normally reclusive Droyne intervened...
Tahavi	010 billion	Non-Human Race	The Tahavi were the first non-human race encountered by the Vilani and their early exposure to a sophisticated technological race has greatly benefited them. They have developed into a powerful race of starfaring merchants despite being an aquatic race greatly hampered in trade with terrestrial walkers...

History-Era: Domains

Most of the domains were never totally absorbed into the Imperium. This was a recipe for disaster.

• Please see Domain for more information.

Six Imperial Domains:
During the Pacification Campaigns, Emperor Artemsus divided space into six regions, labeled them domains, and appointed an archduke over each of them.

To each archduke, he assigned the continuing pacification of the domain’s many systems and their integration into the Imperium. The domains were:

• 1. Antares (Lishun, Antares, Mendan, Amdukan)
• 2. Gateway (Ley, Glimmerdrift Reaches, Gateway, Crucis Margin)
• 3. llelish (Ilelish, Zarushagar, Reaver’s Deep, Daibei)
• 4. Sol (Dispora, Old Expanses, Solomani Rim, Alpha Crucis)
• 5. Sylea (Core, Fornast, Massilia, Delphi)
• 6. Vland (Corridor, Vland, Gushemege, Dagudashag)

Seventh Domain of Deneb:
In 589, during the First Frontier War, a seventh domain was established:

• 7. Deneb (Spinward Marches, Deneb, Trojan Reach, Reft).

The intent was to appoint an archduke to be responsible for their supervision. However, the Civil War broke out before an archduke was appointed.

• Following the civil war, the emperors expressed concern about individuals with powers equaling their own, so they moved to lessen the power of the archdukes in the Imperial government. Because of this, no archduke of Deneb was ever appointed. As a result, the domains came to have little practical significance. Each archduke did retain the power to create knights and baronets.
• In the years after the Fourth Frontier War, and after the problems it presented from lags in communication, Emperor Strephon felt a strengthened archduke position could enable the Imperium to more quickly respond in defending the realm. Against the protests and opposition of some prominent members of the Moot, Strephon reestablished the domain as a level in the bureaucracy of the Imperial Navy and returned to the Domain the ability to collect taxes. Still later, Strephon gave the archdukes the ability to legislate and enforce the desires of the emperor on the local level.
• One of Strephon’s last acts before his murder was to finally appoint an archduke of the Domain of Deneb:
  • Archduke Norris

History-Era: Rebellion

The Divided Imperium: With the assassination of emperor Strephon and all immediate heirs to the throne in 1116, the resulting turmoil has caused some confusion as to who will succeed Strephon to the throne.

• Thus, at the moment, factionalism in the Third Imperium is at an all-time high. Even with the uncertainty of the current moment, the Third Imperium still stands. The archdukes are instituting local stopgap measures until such time as a strong central government can be re-established.

1. Overview of the Third Imperium.
   

Government & Politics (Leadership)

The government of the Third Imperium is a very chaotic yet stabilizing institutional supra-polity widely considered to be a feudal confederation. It is adequately organized to unite in times of trouble yet culturally flexible enough to be tolerant of a very wide variety of sophonts with an extremely diverse spectrum of sensibilities, cultures, mindsets, trophic preferences, and folkways.

Overview: 1105

Overview: 1105:

• Feudal Confederation: The Imperium can be best thought of as a form of feudal confederation. Member worlds of the Imperium agree to pay taxes and obey a few fundamental laws which the Imperium promulgates, known as the High Laws.
• Third Imperium Duties: In return, the Imperium agrees to patrol the space between the worlds, to protect interstellar trade, to encourage travel and commerce, and to arbitrate diplomatic relations between worlds. Beyond this, individual worlds are left to their own devices so long as they acknowledge the power of the Imperium to rule the stars.

Internal Politics: 1105

Any polity or supra-polity as large as the Third Imperium is bound to have a number of competing internal constituents and the Imperium is no exception.

Government Structure: 1105

The Third Imperium holds to classical divisions of governance including an executive, legislative, and judicial branches supported by a large bureaucracy and a powerful military.

• Both the bureaucracy and the military are split into numerous subdivisions.
• The division of power between the three branches is not equal and the executive, through the person of the Emperor, holds supreme power.
• Both the legislative, the Moot, and the judicial are subordinate to the executive.
• Both the bureaucracy and the military answer to the Emperor although the nature of the feudal confederation creates the following status quo:
  • The bureaucracy is largely subordinate to the Emperor with local parts of its subject to various members of the Imperial Nobility.
  • The core of the military, the Imperial Navy and Imperial Marines, is subordinate to the Emperor while many other parts of the military answer to Sector Dukes and local powers.

A. Executive Branch: 1105

Executive power for the Third Imperium is vested in the Emperor.

• The Emperor's power is supreme within the Grand Empire of the Stars.
• Imperial Sanction and Imperial Decree
• Please see Emperors of the Third Imperium for more information.

B. Legislative Branch: 1105

Legislative power, or deliberative power, for the Third Imperium is largely vested in the Imperial Moot, whose members are composed of the Imperial Nobility.

• Some claim the the Emperor has subverted the power of the Imperial Moot, and that the Moot is no longer a representative or deliberative body.
• Please see Imperial Moot for more information.
• Please see Imperial Law for more information.

C. Judicial Branch: 1105

Judicial power for the Third Imperium is vested in the Ministry of Justice.

• The Imperial Ministry of Justice exercises authority over violations of Imperial law, especially when those violations occur on Imperial territory, including within the extrality boundary of starports. Judges, justices, and the other personnel of the Imperial justice system are part of the Ministry of Justice.
• The Ministry of Justice possesses a number of duties including:
  • Imperial Courts: High nobles, acting as the Minister of Justice, operate the Imperial Courts.
  • Imperial Prison System: The Ministry of Justice also maintains the Imperial Prison System to house convicted criminals.
  • Special Agents: Lastly, the Ministry of Justice appoints Special Agents to travel throughout the Imperium to investigate specific cases, and to ensure fair and impartial administration of justice. Most of these agents act with the direct authority of the Minister, and a few have limited Imperial Warrants, making them personal representatives of the Emperor. It is rumored that there are special "super" agents with vastly greater authority granted to them.
• Please see Ministry of Justice for more information.

D. Bureaucracy: 1105

• Institutions: Imperial power is present on member worlds in the form of consulates, bureaucratic offices, bases, and sometimes, larger enclaves of Imperial power are located where they can enforce the Emperor’s will.
• Please see Imperial Bureaucracy for more information.

E. Military: 1105

The military of this polity is subordinate to the supreme executive (civil governor) of this supra-polity, the Emperor.

• Please see Military & Intelligence (Force Projection) tab for more information.

Military & Intelligence (Force Projection)

The Third Imperium is widely regarded as retaining the largest and most powerful military in Charted Space.

• While the centralized Third Imperium maintains an Imperial military, the Imperium, is by nature, a feudal government, and nearly every power-holder under the Emperor maintains additional private militaries if they can. These forces can be called upon and even pressed into the service of the Imperial military.

A. Ground Forces: 1105

This military, the ground forces of the Third Imperium or the Imperial Army, includes:

• Imperial Army
  • Close Orbit and Airspace Control Command
  • Ground Force Command
  • Nautical Force Command, a Wet Navy

The Imperium also regulates and even sometimes hires:

• Mercenaries

B. Naval Forces: 1105

The Imperial naval forces are the largest branch of the military of the Third Imperium. The IN patrols the interstellar highways and maintains the stability of the interstellar trade order while maintaining enough distance and cultural tolerance for some very diverse cultures to prosper. The Navy primarily consist of the following divisions:

• Imperial Navy
  • Imperial Marines

Naval Technology: Vast resources beyond the Quadrant. The bulk of the Navy is built to Tech Level 15 standards with some newer models incorporating Tech Level 16 breakthroughs. The fleets of the Quadrant have not yet completed the transition from Tech Level 14 standards.

• Please also see Imperial Rules of War for related information.

C. Special Forces: 1105

The Imperial Marines are the most elite regular forces unit available although many kinds of special forces exist within the marines, army, and the IISS.

Some of these elite forces include:

• Imperial Guard
• Protected Forces (ProFors)
• Rapid Interface Forces (RIF)
• Sylean Rangers

D. Paramilitary Forces: 1105

Related paramilitary institutions that support the Imperial military includes:

• Imperial Interstellar Scout Service
  • Express Boat Network
• Mashkim (System or Planetary Police)
  • Ducal Security Forces
  • Mainworld Security Forces (Constabulary)
• Mercenaries
  • Irregular "For Hire" Mercenaries
  • Regular Contractual Mercenaries

E. Intelligence Agencies: 1105

A related intelligence-gathering institution that supports the Imperial military includes:

• Imperial Interstellar Scout Service (IISS)
  • Imperial Intelligence (ImpInt)

• Imperial Intelligence Command (ImpCom)
  • Imperial Naval Intelligence (INI)
    • The INI can draw on the assets of the entire Imperial Navy and is primarily concerned with military intelligence; it tracks starship and troop operations, and can mount intelligence gathering activities into all parts of the Imperium.
  • Imperial Ministry of Justice (MOJ)
    • The MOJ is primarily concerned with Imperial society; it has contacts with the court systems of the worlds of the empire, and it has an intelligence network which concentrates on criminal activity. The MOJ is especially valuable when dealing with the criminal elements of the empire and can offer great rewards (in terms of amnesty or pardon) to those who support its mission.
  • Imperial Secret Service (ISS)

Technology & Trade (Economy)

The Imperium maintains a very high level of interstellar trade and uses the Imperial Military to maintain the safety of the spaceways.

Technology Timeline: 1105

A rough timeline of technological achievement is as follows:

• (-1776): TL-10 Syleans maintain minimal interstellar trade
• (-650): TL-11 Sylean Federation established
• (-150): TL-12 Robot manufacturing reestablished
• (300): TL-13 Vargr Campaigns taking place (210-348)
• (700): TL-14 Xboat system being built (624-718)
• (1000): TL-15 Solomani Rim War taking place (998-1002)

Interstellar Commerce & Trade: 1105

Interstellar commerce and trade are the foundation of the Third Imperium and such trade is considered of vital importance to the Emperor. Great efforts are extended to provide a stable and secure environment in which to trade. While trade is regulated to a degree, the commercial environment on the interstellar scale is largely laissez faire and is often far more regulated by local duchies and world or system governments than by the Imperium itself. As long as the Imperium receives its share, the other details are left to local governments.

Corporation Listing: 1105

The following businesses operate out of or in this polity:

• Megacorporations
• Corporations
• Interface Lines

Interstellar Currency & Finance: 1105

The Imperium uses the Imperial Credit, informally known as the Crimp, as its currency. The Crimp is well-known for its stability and ability to hold value.

• Please see Imperial Currency for more information.

Research & Technology: 1105

Scientific research is of great importance to the Third Imperium and the government conducts vast experiments to refine and develop existing technology.

• Corporate Research Center
• Imperial Research Station
• Megacorporate Research Center
• Private Research Center

Calendar & Timekeeping (Chronology)

The Third Imperium maintains a standard calendar, which sets a timekeeping baseline for all parts of the Imperium.

• Please see Imperial calendar for more information.

Calendar Specifications: Imperial dates count from the year of the founding of the Third Imperium, specifying the year zero as a holiday year.

• Dates before that are negative; dates after that are positive, usually with the sign suppressed.
• Imperial dating uses a Julian system for specifying days.
• Each day in the year is consecutively numbered beginning with 001.
• Thus, in the year 1105, the first day of the year is 001-1105.
• Weeks of seven days and months of 28 days are used to refer to lengths of time, but rarely to establish dates.

Mathematics: 1105

The majority of the Third Imperium has standardized on a Base-10 system of mathematics, including:

• Mathematical logic
• Arithmetic
• Statistics
• Particle mechanics
• And other branches of mathematics.

Political Divisions: 1105

Territorial Organization:

• The Imperium’s territory is divided into sectors.
• These are, in turn, divided into subsectors and systems.
• Groups of sectors, called domains, have been created above the sector level.
• Some parts of sectors are further subdivided into duchies and counties.
• Frontier areas are sometimes designated districts and later given more formal subsector designations as development occurs.
