No one who needs an accurate map of the stars will find a use for the Imago Mundorum. It doesn’t tell astronomers where to point their telescopes at, in the skies of their disparate nights; astrologers can’t make any mystical sense of planets dancing around the far away suns it catalogues, and it’s far too imprecise, even in its more detailed versions, to chart the course of interstellar ships by it. The map makes no effort to represent three-dimensional space, and the indication of coordinates in the z plane is poor compensation, so it gives the reader an utterly distorted view of our universe.
Yet, ever since Archchancellor Albrecht I came up with the basic design, not long before founding our Universal Archive of Human History, it has managed to remain a popular cultural artifact. Often updated, not always truthfully, it remains a bestseller in bookstores all over. As a huge fresco painted over the main hall of the Archive’s refectory, it never fails to draw up the eyes of tourists until their necks hurt, making it the pride and joy of our order’s ancient home. Yes, the map has no use, but it kindles true awe in the heart of everyone who sees it. All other projections fail to enrapture the soul as it does, accurate as they might be.
It promises answers for those who await a ship to come into dock at the orbital caravanserai, loaded with its precious cargo of perfumes and silks, not to mention invaluable terraforming equipment, newly engineered seeds, frozen embryos, machine- animas, and colonists. However vaguely, the map gives people the means to follow the progress of the vessel carrying word of a son who went away looking for fortune. It tracks the whereabouts of the many void-sailors who once fell into the hearts of landlubbers, with charm and wild stories, and who promised to come back after the twenty, fifty or even after the hundred Sol-years that their journeys might take them. It’s impossible to conceive how long it takes for things, people, and even information to travel between stars, but the map puts it all in a more human scale, even if it makes a lie of itself in the process.
Designed to fit exactly onto a standard sheet of paper, it mainly centers on the stars of the Hub Circuit, the nine systems connecting the paradise suns, the g-class, main-sequence stars that host the worlds most hospitable to life: Virginis, Pavonis, Hydri, Böot, and those beyond, the Herculis triplet, and Arae. Even more g-class stars are within reasonable reach, like Draper and Cordoba, accessible now that Durchmusterung, the steppingstone, has been sufficiently terraformed and colonized. Hanging on the branch that goes off from Ophiuchi Distans, the mysterious λ Serpentis is rumored to host one of the most beautiful planets ever found, though the Sagittarius Company, ever putting shareholder interest above all else, keeps a shroud of silence around the star without offering any explanation for it.
By contrast, the nine worlds of the Circuit are not so lush—indeed, except for Çierúsa and Guniibuu, they are often hostile to Terran life, yet their relative closeness to one another, on average at a distance of 5.5 lightyears, makes them an ideal nexus between the more habitable systems. Without the establishment of the Circuit, humanity would be scattered across distances too vast to traverse safely. At the center of it all, the Honorable Sagittarius Colonization Company has kept its headquarters at Höfa for over ten thousand years, and Gran Glisa, host to our order’s Archive, is so strategically placed that it has become the homeport of some of the most important shipping houses, even with a tidally locked planet and a star prone to violent outbursts of radiation. Understanding the Circuit means understanding how our human worlds are woven into the fabric of an interstellar civilization.
And the idea of a coherent human civilization this side of Sol is perfectly expressed in the map. That’s why the Imago Mundorum appears in the primers of children and college students alike, there to support the claims we historians make about the distant origin of our species, though Terra-the-Cradle is in fact beyond the page’s edge, to the left. The map is found in novels about love and strife elsewhere, in encyclopedias, and in any place where there’s a need to picture our human worlds at a glance. Even the great shipping houses use it as a handy tool for explaining to prospective passengers what route they will take from here to there and back. The merchant princes trace it with scrawny fingers to show the road their cargo has traveled from lightyears away, thus justifying the exorbitant fees the houses charge for their services.
A rich socialite will dress only in gowns of Comae Berenican silk of the most vivid pink, cyan, and silver. A poor, destitute family will cling on to a cup of carved diamond from Herculis, one last heirloom they haven’t dared to sell. Shareholders of the Company, thousands of years old, will fix events in their overtaxed memories with a drop of perfume, made from flowers grown under the orange sun of Çierúsa. A respectable grandparent will get a twinkle in the eye when struck by a memory of youthful excess and the splash of Guniibuunian brandy that was its height. All will look at the map and say to themselves: “this precious thing I hold in my hands came from there, so far, so long ago.”
Many a young boy or girl has showed up at the spaceport’s gate, asking to be let through so they can go up on a rocket and then out on a ship with many roaring antimatter engines, all burning as bright as Sol does in legend. They dream of 0.5 or 0.6 lightspeed, and the more ambitious kids will want to go on a fast post-runner, at 0.8 c. A copy of the map can always be found in their pockets, the seed of their dreams.
There are, of course, versions for all tastes and purses. Basic, functional prints for quick consultation in textbooks; streamlined copies for the quarters of high-ranking officers of the Sagittarius Company, who lose their good health over the nightmare of logistics that their terraformation projects entail. Powerful businesspeople have it engraved on their desks, with rubies and yellow sapphires to show suns, the names engraved with pearl, routes inlayed in gold and the background with lapis lazuli. It can be found as a splendidly decorated illumination, hand painted for the refined collector, or sometimes with dreadfully scary monsters drawn in the spaces between stars, in books for children and games of adventure. Those made for device-screens are normally programed to show additional information when the user selects this or that feature, but most people feel that this takes away from the romance of the map; it lessens that feeling of awe that overtakes those who stare at the paper for hours and hours, resting chin on hands, maybe sipping cocoa while fantasies run wild.
Perhaps you have stared at the Imago Mundorum and wondered, maybe you have thought about visiting some of these worlds or even about completing the Grand Tour around the Circuit.
You surely have no use for such a map, but it holds a dream.

Bio:
Arturo Sierra lives in Santiago, Chile, quite happily. So far he has lead a completely uninteresting life, and, with any luck, it will stay that way.
Philosophy Note:
It seems that the first thing a fantasy author does, to get the juices flowing, is draw a map. It really is a good place to start, as one’s imagination naturally starts to run wild as it sees shores, mountains, and forests pour out from a fanciful pen. Space opera doesn’t have that luxury, not if it aims at a minimum of real-world science, instead of—as otherwise is perfectly legitimate—going full Star Wars and treating the Galaxy as if it were a flat continent with neatly drawn borders, places of interest, and regions of avoidance here and there. The closest thing to a realistic interstellar map I have seen is a rather paltry one for Alastair Reynold’s Revelation Space, which makes one squint rather than imagine new adventures. 2D maps mostly end up being too abstract, 3D ones are impossible to read, for the most part. I wanted to get around some of those issues, making the map as realistic as possible while still allowing my imagination to feel tickled.
What’s presented here is an entirely accurate map of near-Sol space, up to more-or-less 8 parsecs pointing from Earth towards Sagittarius at the center of our Milky Way. The stellar coordinates, the stellar classification, and the distances between stars are real, though some convenient rounding-up has been applied here and there. Stars with proper names, such as Guniibuu and ε Indi, have kept them, but stars with only a catalogue-number for a name have been baptized with something a bit more stimulating. Some of these stars are known to host planets in the habitable zone, but I’ve not included anything about that.
This map would not be possible without the wonderful resources made available for free by Winchell D. Chung, creator of one of the last truly awesome places on the internet, the Atomic Rockets site, as well as the data catalogued in the Internet Stellar Database, curated by Roger M. Wilcox. Not to mention the Hipparcos and Gaia missions.
