|Acheron (star system)||Not only one of the Seven Systems, but the first of the systems to be colonized by humanity some 4,500 standard years ago. In a sense, it is the core of the core systems.||Acheron Prime, Core Systems, Wessex|
|Acheron Prime (planet)||The throneworld of the Imperium and official residence of the Imperial Court (although the emperor often conducts business from the fortified moon of Litochoro). "Standard Imperial Time" for both the length of a day and the year is based on that of Acheron Prime. In fact, all official calendars and chronographs throughout the Imperium are required to display this "standard time" whether or not it relates to local planetary rotations or orbits. Naturally, local timekeeping abounds for both practical and cultural reasons, but standard Imperial time is what is used aboard most ships. |
Acheron Prime is also the location of the island continent of Wessex.
|Aerobraking||A spacecraft maneuver where a ship enters the atmosphere of a planet in order to create drag and change its orbital position without the direct use of rocket engines.|
Learn more about the actual science behind aerobraking on Wikipedia.
|Batori||A moon in the Shantung system and the site of Batori Integrated Shipyards, the legendary spacecraft design and manufacturing conglomerate which now covers almost the entire surface of the natural satellite. Nearly every spacer wishes his or her ship was "Batori-built" and often pays handsomely for custom parts and fittings to give their own spacecraft that extra edge.|
The Shipyards are now a public-private partnership administered by House Xinwei-Moore through a lucrative long-term contract with the Emperor. Almost all imperial warships are Batori-built and one of the Imperium's fleets is always on station in the system (a circumstance House Xinwei-Moore would resent were it not for the monits involved).
|Bearce||An omnipresent brand of spacecraft parts known, used, and generally liked throughout the Imperium.|
|Chaff||Also referred to as 'sensor chaff.' Any of a number of ship-launched counter-measures meant to make the ship harder for enemy ships or missiles to target.|
|Commerce Raider||"Commerce Raiders" are the official Imperial term for pirates. Piracy has existed in one form or another since ancient times, but--according to the Imperium--piracy no longer exists. However, while it is next to non-existent in the core systems, it still occurs with depressing regularity in the outer worlds. Because it is usually difficult to predict jump points between star systems and those predictable jump points are usually guarded, pirates attack ships in-system, hoping to capture prey that stray off established trade lanes and therefore may be further away from help. Official reports and documents term these attackers "commerce raiders" which, for some reason, are completely different from pirates.|
|Core Systems||Usually a synonym for the Seven Systems, though Vendawundjo (the "Eighth System") is often implicitly included when people refer to the Core Systems.|
In addition, people on Outer Worlds sometimes refer to the 20 systems closest to Acheron as the Core Systems.
|Corvallis (star system)||One of the Seven Systems and the seventh and last colonized by humans in ancient times.|
Although the star system is just as developed as the rest of the core, it retains a reputation for being more "unspoiled." To be fair, it features some of the most well-regarded nature preserves in the Imperium.
|Courier (spacecraft type)||A small ship built for speed (both in system and via FTL). Couriers are used commercially for important deliveries and militarily as packet ships.|
|Coutharian||A sentient species that has an uneasy alliance with the human-dominated Imperium.|
|Earth||A mythical setting occasionally used in fairy tales and bedtime stories.|
Scholars and astronomers (and scholarly astronomers) understand that Earth did and probably still does exist. However, several millenia of cultural prejudice combined with the destruction of most records prior to the System Wars mean that no one is inclined to find out the fate of humanity's ancestral home.
|Flatrock||Flatrock is a massive spaceport bordering, but not part of, the territories of several great houses. Its name comes from the fact that the majority of its surface area is on an artificially constructed shelf, lying upon, but far outreaching an ancient asteroid. Based on its convenient location along the trade routes to different houses and its proximity to the Frontier, Flatrock is among the busiest spaceports in the Imperium. |

|FTL||An acronym for "faster than light." All interstellar spacecraft have an FTL drive or "jump drive" that enables the ship to briefly fold space-time in order to travel faster than the speed of light and bridge the vast gulf of space.||FTL drive, Jump|
|FTL Drive||An essential piece of machinery on any interstellar spacecraft, FTL drives vary greatly in size and power. Variables include the distance traveled with each jump (the longer the better for interstellar freighters) and the time required between jumps (the shorter the better for military vessels). The performance of an FTL drive is greatly influenced by the skill of a given ship's pilot. Most career pilots know their ship's drive limitations intimately and are able to coax the maximum performance out of them without drives overheating or other damage.|
FTL Drives are separate from a ship's standard propulsion, though the two systems may be used in tandem, especially for in-system travel and/or military situations.
|Giustra Reverse||A spacecraft maneuver using only a ship's momentum and minimal thrusters to turn the ship 180 degrees in a short amount of time (usually within 5 seconds). This allows the ship to quickly apply thrust in the opposite direction -- an especially useful tactic in combat situations.|
Although such a maneuver has been independently discovered before and since, it frequently credited to Dr. Josiah Giustra, a spacecraft designer and avid racer, who introduced the reverse as well as improved ergonomic pilot controls in the Venusia 5 Million Space Race.
The Giustra Reverse has since been a common maneuver taught to combat pilots and can even be employed by skilled freighter pilots (provided they have a good knowledge of their ship).
|Grand Armada||A massive fleet of the Imperial Navy said to be able to lay waste to an entire star system. The last known Grand Armada was formed during, and aided in the conclusion of, the Border Wars, but the possibility of the formation of a new Grand Armada keeps the Houses in line--or at least from threatening the Emperor directly.||Imperium|
|Gravity well||Any pull of gravity a large body, such as a star, planet, or moon, exerts on its surroundings. Understanding the strength of various gravity wells is crucial to spacecraft navigation, especially when calculating jumps as most FTL Drives cannot make jumps inside strong gravity wells.|
Learn more about the real science of gravity wells on Wikipedia.
|FTL drive, Jump|
|Haapsalu 3||The most densely populated planet in the Haapsalu system, which isn't saying much. Haapsalu 3 is largely given over to agriculture and--in recent decades--aquaculture. It has a few active spaceports which enable it to export its foodstuffs to the territories of House Kalmar and the rest of the Imperium.||Haapsalu, Haapsalu 6|
|Haapsalu 6||A gas giant in the Haapsalu system with several moons and large asteroid fields at some of its L-points.|
Haapsalu 6 has historically been a mining location due to rich mineral deposits found in many of its asteroids. However, no mining company has kept a permanent operation since the Border Wars, after which the Saluvian economy switched primarily to the agricultural exports of Haapsalu 3.
|Haapsalu, Haapsalu 3, L-Point|
|Haapsalu (star system)||Originally part of the territory of House Malde, it was taken over by House Kalmar during the Second Unification War.||Haapsalu 3, Haapsalu 6|
|House (Imperium)||Usually referred to as "Great Houses," these hereditary families of nobles constitute the main form of government in the Imperium. Indeed, apart from the Imperial Literacy Programs and other universal mandates, a citizen's Great House is the only government they ever know. Houses usually hold sway over 5 or more star systems, and constantly compete with one another for more Imperial contracts, corporate interests, or other ways to grow their influence. It is said the the Emperor will often play one house against another to avoid the consolidation of too much power by any one house.||Imperium|
|Hraggedor (star system)||One of the Seven Systems and the third colonized by humans in ancient times. In the fifth century of the Imperium (current times), it does not have permanent settlements, but is a commonly used route through the core.||Seven Systems|
|Imperium||An interstellar empire spanning close to 100 star systems, the Imperium maintains control of its realm through a neofeudal form of government where Great Houses administer much of a region's affairs, but all are linked and are pledged to serve the empire. The Imperial Navy helps reminds both the nobility and common citizenry of this pledge and the threat of a Grand Armada ensures no House will defy the Emperor's will.|
|Interloper (spacecraft model)||The last of the Wessex Patrol Service's Acheron-built survey cruisers. The Interloper is one of the longest-lasting and most beloved starship designs due in great part to the degree a captain could customize the ship to his or her needs.|
|Jump (space travel)||A folding of space and time used by spacecraft equipped with an FTL Drive (sometimes called a "jump drive"). Jump technology is crucial to the functioning and administration of the modern Imperium, although less advanced jump drives date back to ancient times.|
The distance and frequency of a spacecraft's jumps are limited by the quality of its FTL drive, the skill of its pilot, and the proximity of gravity wells.
|FTL Drive, Gravity Well|
|Kalmar (star system)||One of the Seven Systems and the sixth colonized by humans in ancient times.|
It is also the home star system of House Kalmar.
|Kaoliang||Also sometimes referred to as gao liang je, kaoliang is liquor distilled from sorghum. It has enduring popularity in both the Shantung and Nominal systems and occasionally comes back into fashion in parts of the Acheron system -- though never by the aristocracy who view it as "a farmer's drink." |
Kaoliang is not hard to find in most spaceports, though the quality can vary greatly from port to port.
|Kolkiss District||A district of Flatrock near to the main port dominated by warehouses and light manufacturing. Named for Stefan Kolkiss, one of the original shipping magnates who made his fortunes on Flatrock.||Flatrock|
|L-Point||A common term among spacers also known as libration points -- and by academics in the Imperium as Lagrange or Lagrangian Points. |
It is not uncommon to find asteroids at L-points of certain large planets, such as gas giants. Satellites and spaceports are often placed at L-points due to their relatively stationary position.
Learn more about the real science behind L-points on Wikipedia.
|Monit||The basic form of currency used throughout the Imperium.|
|Nokari||Originally the warrior caste of the otherwise peaceful Stahnkari race, the Nokari have kept themselves separate from their more academically-minded brethren for hundreds of years. They have built a reputation as resourceful and inventive mercenaries since the Unification Wars.|
|Nominal (star system)||One of the Seven Systems and the fifth colonized by humans in ancient times.|
The system serves as the headquarters for a disproportionate number of the Imperium's engineering and banking firms.
|Pirate||See 'Commerce Raider'|
|Saluvian||A native of the Haapsalu system.|
|Sensor chaff||See 'Chaff'|
|Seven Systems||The original systems settled by humanity and the extent of the "known universe" for hundreds of years.|
Many classic works of art and literature are set during the ancient times thousands of years ago, when there "were only" the Seven Systems, well before the Imperium.
The Seven Systems, in the order they were first settled are Acheron, Shantung, Hraggedor, Venusia, Nominal, Kalmar, and Corvallis.
|Shantung (star system)||One of the Seven Systems, the second system colonized and currently one of the most densely populated areas of the Imperium. Shantung is the center of several key industries including communications and increasingly spacecraft manufacture.||Seven Systems|
|Sindanese||A tonal language originating in Shantung and spoken by roughly 35% of the Imperium as either a primary or secondary language.|
|Slag||Spacer slang term for an asteroid.|
|Spacer||Anyone who makes a living crossing the oceans of space. There are many romantic archetypes of spacers in novels and tri-vids throughout the Imperium and many spacers are both rich and influential. However, in practical terms, most of the Imperium's citizens live their whole life on one planet or certainly within one system, and look on spacers with mistrust, as a necessary lower class for interstellar commerce.|
|Spice||Not much is known about the spice... except that it must flow.|
|Spranta||The common language used throughout the Imperium. 99.99% of the Imperium's citizens speak Spranta as either their primary or secondary language. Imperial literacy programs ensure this goal.|
|Venusia (star system)||One of the Seven Systems and the fourth colonized by humans in ancient times.|
Venusia competes with Shantung as one of the most densely populated and developed star systems in the core and Venusian spacers, especially the "Space Gauchos" of the Acheron Thalassocracy are a popular subject of Tri-Vid programs.
|Seven Systems, Wessex|
|Wessex||An island continent on Acheron Prime whose culture came to dominate not only the system, but the whole of the Seven Systems in ancient times through the Acheron Thalassocracy. Although its influence has waxed and waned over the millenia, Wessex still influences -- some might say disproportionately influences -- cultural trends and mores throughout the Imperium.|
|Xinwei Prime||A hub of commercial activity -- especially communications -- and the home of House Xinwei-Moore.|
|Xinwei-Moore||One of the more powerful Houses. In the past decade, it has often competed with House Clarke-Timurin for influence through the Imperium through methods both legal and very questionable. They like to get their way.|
