Below is the newest version of the introduction for the Game Maps Rules Doc. As Haegan can attest to, I created a new Stellar Coordinate System that we are going to use in BTS! The New Stellar Cartography rules will be posted in the BTS! fora.
As always, comments are requested.
[2.0] THE GAME MAPSSince the dawn of time as the species of the universe began to spread themselves to other star systems, they learned that stellar cartography was an entirely new level of mapmaking. It is easy for someone to imagine the two dimensional nature of a planet's surface and to draw boundaries across it. Space, however, is three dimensional. It does not fit well on the two dimensional maps frequently used by star nations.
Beyond the Stars! has chosen to make such representations 'top views' of the galaxy, and thus making the 'depth' of the galaxy the Z-axis. But such 2D star maps are, as one might expect, horribly inaccurate.
Just as space is 3D, so are the interstellar borders between Star Nations. A star on one XY-axis coordinate could be in the UST and another star on the exact same XY-axis coordinate, but a few light years away on the Z-axis, above or below, could be in the Numerian Commonwealth. Proper 3D political maps, usually represented in holographic fashion, were generally giant globs of irregular-shaped masses, each with salients into each others space.
Sometimes you could come upon a straight line or 'wall' where expansion treaties or peace treaties from one or two centuries before had cleanly delineated lines of control. But, for the most part, the lines were irregular and misshapen, testimony to the struggle for rich and wealthy star systems amongst the empires.
[2.1] THE MILKY WAY GALAXYThe Milky Way is classified as a Barred Spiral Galaxy, which is roughly 13 billion years old. It is estimated that it has a diameter of 100,000 light years, a core thickness of 15,000 light years and a stellar population of 500 billion stars. It is divided into four quadrants, the Orion, the Scutum-Centarus, the Norma, and finally, the Sagitarius quadrant. The Galaxy consists of four major, Perseus, Scutum-Centarus, Sagittarius, and Outer, three minor, Near 3KPC, Norma, Far 3KPC, arms, and one spur, Orion.
The Perseus Arm has it's beginning on the northeastern end of the Galactic Bar, and is the closest arm to the Orion Spur, where Sol is located, and wraps through all four quadrants. Rimward of the Perseus Arm is the Outer Arm on the southern edge of the galaxy, which stretches through the Orion and Scutum-Centarus quadrants. The Orion Spur, mentioned earlier, is located between the Perseus and Sagittarius Arms. The Orion Spur give this quadrant it's name, the Orion Quadrant and straddles the Orion and S-C quadrant border. The Scutum-Centarus arm has it's beginning at the southwestern end of the Galactic Bar and winds it's way around the galaxy to peter out before it re-enters the Orion quadrant again. The Norma arm begins near the S-C / Norma quadrant borders and peters out before stretching into the Sagittarius Quadrant. The Sagittarius arm begins near the far side of the Galactic Bar from Sol and winds itself around until it peters out just before re-entering the Sagittarius quadrant. The two 3KPC arms are minor arms that begin and end near their respective sides of the Galactic Bar, Near and Far.
The population I stars in the galaxy's spiral arms tend to be young and towards the blue end of the spectrum, while the population II stars in the galactic core tend to be older and towards the red end of the spectrum.
Our local group of galaxies includes two very large spiral galaxies, the Milky Way and the Andromeda or M33, 2.2 million LY away, galaxies, and several dozen smaller, mostly irregular, galaxies that cluster around the two giants. The Large, 179,000 LY away, and Small, 210,000 LY away, Magellanic Clouds are satellites of the Milky Way, while the SagDEG is a dwarf erratic galaxy in the process of colliding with our own. Globular star clusters populate the galaxy's halo, and are concentrated near the galactic core. There are also migrating globular clusters located between the galaxies in intergalactic space.
This was cut down for the rules from this, which is in the Stellar Cartography Doc.
INTRODUCTION
Since the dawn of time as the species of the universe began to spread themselves to other star systems, they learned that stellar cartography was an entirely new level of mapmaking. It is easy for someone to imagine the two dimensional nature of a planet's surface and to draw boundaries across it. Space, however, is three dimensional. It does not fit well on the two dimensional maps frequently used by star nations.
The Terran Galactic Mapping Department, run by NASA (National Astrographic and Space Administration), has since chosen to make such representations 'top views' of the galaxy, so as to show all four galactic quadrants, and thus making the 'depth' of the galaxy the Z-axis. But such 2D star maps are, as one might expect, horribly inaccurate.
Just as space is 3D, so are the interstellar borders between Star Nations. A star on one XY-axis coordinate could be in the UST and another star on the exact same XY-axis coordinate but a few light years away on the Z-axis, above or below, could be in the Numerian Commonwealth. Proper 3D political maps, usually represented in holographic fashion, were generally giant globs of irregular-shaped masses, each with salients into each others space.
Sometimes you could come upon a straight line or 'wall' where expansion treaties or peace treaties from one or two centuries before had cleanly delineated lines of control. But, for the most part, the lines were irregular and misshapen, testimony to the struggle for rich and wealthy star systems amongst the empires.
The United States of Terra, on any map, is the largest entity. Ten thousand light years across at it's widest point, albeit one that stretches across all three dimensional axes, where it encompasses millions of cubic light years. It is centric to the Orion Quadrant, while extending into the Scutum-Centarus Quadrant, Some star nations have begun regarding the UST as a 'galactic superpower' in the making.
On it's S-C Quadrant side are the hearts of the Atheri, Median, Roman, Iskarendi, Nanri, Tsak, Dardanii, Graal'thak, and Denevan space. Although the Atheri have extensive Orion Quadrant holdings, curling under and over as well as, in some areas, around Terran space respectively. The Atheri frontier finally makes contact with the Numerians, separated from the UST only by a collection of independent, hardscrabble colonies settled by the various species.
The Tsak, Graal'thak, and Nanri share common borders with the Iskarendi Confederation. The Nanri border is the smallest, only about twenty thousand cubic light years, while the Graal'thak border is nearly thirty-five thousand cubic light years. Finally, the Iskarendi-Tsak border is well over one hundred thousand cubic light years and very frequently changing due to the frequent border wars between the two powers.
Iskarendi space meets Terran territory, including Dardanian space, and encompasses the Iskarendi portion of the border. Near the other side of Iskarendi space, where it meets Median and Roman territory, are the Denevans, where the shunned but highly-advanced Felinoid species lives.
The Orion Quadrant tends to be heavily populated with many small star nations. Two hundred years ago it had been the 'Hotspot of the Milky Way', as border war after border war cropped up amongst the locals and the newer arrivals to the region, like the UST. The Penamor, the Draugir, the Mortao, the Gomesah Lords, the Ch'thpch Nest, the Halaorian Council, and at least half a dozen more interstellar powers had spent the last few hundred years warring with one another.
A mention must be made of the one galactic power that is, literally, the eight hundred pound gorilla in the galactic playground, the Numerian Commonwealth. As long as you do not bother them, they will not bother you. Non-expansionist and static, they are left alone by all sane star faring powers. But, if you rouse their ire, they will not hesitate to commit genocide. One reason why the Numerians are both feared and despised. Most of the Orion and S-C Quadrants look forward to the day when Numeria is just a word to scare their children into good behavior with.
THE MILKY WAY GALAXY
The Milky Way is classified as a Barred Spiral Galaxy which is roughly 13 billion years old. It is estimated that it has a diameter of 100,000 light years, a core thickness of 15,000 light years and a stellar population of 500 billion stars. It is divided into four quadrants, the Orion, the Scutum-Centarus, the Norma, and finally, the Sagitarius quadrant. The Galaxy consists of four major (Perseus, Scutum-Centarus, Sagittarius, Outer), three minor (Near 3KPC, Norma, Far 3KPC), arms, and one spur (Orion).
The Milky Way consists of the following arms and spurs: The Perseus Arm has it's beginning on the northeastern end of the Galactic Bar, and is the closest arm to the Orion Spur, where Sol is located, and wraps through all four quadrants. Rimward of the Perseus Arm is the Outer Arm on the southern edge of the galaxy, which stretches through the Orion and Scutum-Centarus quadrants. The Orion Spur, mentioned earlier, is located between the Perseus and Sagittarius Arms. The Orion Spur give this quadrant it's name, the Orion Quadrant and straddles the Orion and S-C quadrant border. The Scutum-Centarus arm has it's beginning at the southwestern end of the Galactic Bar and winds it's way around the galaxy to peter out before it re-enters the Orion quadrant again. The Norma arm begins near the S-C / Norma quadrant borders and peters out before stretching into the Sagittarius Quadrant. The Sagittarius arm begins near the far side of the Galactic Bar from Earth and winds itself around until it peters out just before re-entering the Sagittarius quadrant. The two 3KPC arms are minor arms that begin and end near their respective sides of the Galactic Bar, Near and Far.
The population I stars in the galaxy's spiral arms tend to be young and towards the blue end of the spectrum, while the population II stars in the galactic core tend to be older and towards the red end of the spectrum.
Our local group of galaxies includes two very large spiral galaxies, the Milky Way and the Andromeda or M33 (2.2 million LY away) galaxies, and several dozen smaller, mostly irregular, galaxies that cluster around the two giants. The Large (179,000 LY away) and Small (210,000 LY away) Magellanic Clouds are satellites of the Milky Way, while the SagDEG is a dwarf erratic galaxy in the process of colliding with our own. Globular star clusters populate the galaxy's halo, and are concentrated near the galactic core. There are also migrating globular clusters located between the galaxies in intergalactic space.
