The Cathedral Galaxy: so named to evoke an awe-inspiring structure; something built over generations. Eons before the advent of starflight, the Ancients – Progenitors, Precursors, Archaics, Elders – constructed a galaxy-spanning civilization. They learned to harness energies, manipulate matter, and gather information on a vast scale, ultimately building a network of wormhole passages across the galaxy. At the height of their power, they encountered a malevolence from outside the galaxy: some think an evil intent, some say a natural phenomenon. Nobody yet knows what happened to the Old Ones. Perhaps they died. Perhaps they absconded. Perhaps their essence remains embedded in the constructs they left scattered through the galaxy – some still functioning at mysterious purposes, some long torn down by the forces of gravity and radiation. Perhaps the Elders even remain alive. After all, ages after empires have risen and fell and risen again, no one has penetrated the dense, irradiated Cathedral at the galaxy’s heart.

Thousands of years ago, the first modern peoples discovered the principles of spatial trajection. With this starflight capability, a ship could disappear from normal space and, a fixed time interval later, reappear some light-years away. They soon found ruins of the Prior civilization. Eventually they located the Founders’ great Anchors, entry points to the wormhole network, providing instant transit – much better than time-consuming and energy-intensive trajector jumps. Many other peoples followed suit, and the wormhole passages thus became channels of commerce and information allowing galactic civilizations to be built again. Through their history, the peoples of the galaxy have always been keenly aware of those who came before – and all that has been lost, exemplified by the nonfunctional wormhole gates drifting near many of the active Anchors. Now, the galaxy has reached a relatively stable state. Decadent empires, considered republics, brave adventurers, learned researchers, inventive scavengers, and noble warriors make their home in this galaxy, from the populous core nations to the empty frontier fringes. 

It is a galaxy of both promise and stillness at this moment in time. After eons, what is an extra nova in the uninhabited core? What is a rumor of new Anchors opening, or existing Anchors closing, but a rumor? And what is an archaic megastructure activating instruments, seeming to seek for something outside the confines of the galaxy, but a relic running an obsolete program…?

I have been mulling an improved map of the Cathedral Galaxy for some time, and finally bit the bullet. (Here’s the original.) For this improved and expanded version, my method was to draw the line art in black pen on white paper, then invert a photograph and color/manipulate it in Photoshop. I’m pleased with the result.

This galaxy is full of places to explore, including the settings for my short stories “Between Wrecks,” “In the Arena,” and “Conference.”

Amseile, a proud young realm nestled in two star-forming nebula regions. After uniting from several independent systems in 18k450, Amseile fought a devastating war with Shobah with lasting effects on galactic politics to this day.

The Axiom Republic, a large, baroque state of learning and cultural achievement. The Republic’s central location in the galaxy means that it contains many Precursor artifacts such as the Spire and Taron’s Throne, as well as celestial phenomena like the emission nebula Twin Idols, dust clouds of Onyx Space and Silver Run, the active Sapphire cluster, and the end-of-life star Khalkeus that sheds heavy elements.

Harrow’s Core, home of two enigmatic peoples who believe, among other strange ideas, that the galaxy itself is a living organism. There are rumors that a secret and powerful Archaic weapon prevented other polities from absorbing the Core during their expansionary phases.

The realms of what the core nations call the Exiles, nearly cut off from the rest of the galactic network by a quirk of the arrangement of wormhole passages: Babylon, a decadent theocratic empire; the Free Worlds, a xenophobic and militant confederation; and the Underworlds, domain of a people stereotyped by the rest of the galaxy as the Dead Ones – according to one legend, the last of the Ancients, but robbed of their faculties. The Panther Nebula, a dust cloud with an obviously recognizable shape from throughout the Burial Grounds, signals adventurers away from this region.

The Far Reaches, a spiral arm of the galaxy with a sparse population but many lesser Elder relics.

The Imperium of the Triumvirate, once a vast empire, now reduced to three closely allied provinces each under its own despot: technologically advanced, aggressive, and lacking restraint. The Imperium’s skirmishes are not always with other nations. Aoreu is known for the exotic star-forming Menagerie, but the true symbol of the Imperium is the Coliseum, a Progenitor-built sphere surrounding a white dwarf, where biomechanically modified beings battle for citizens’ amusement.

The Mariner Worlds, a loose affiliation of wanderers, not all native to this sparse region or even to the galaxy itself.  Among these worlds are Harbor, a focusing construct partially surrounding an unusual dwarf star that appears on the verge of collapse to a neutron star; Haven, a resource-rich protoplanetary disk; and the Lighthouse, an array of transmitters and instruments aimed into the extragalactic medium.

Shobah, a nation of rigid structures and protocols, home to a sect of Librarians who believe that the Ancients discovered all knowledge it is possible to find, and therefore focus all research on the ruins scattered throughout the galaxy. Knowledge gleaned from the Ancient wrecks helped Shobah fight off Amseile’s incursions in the war.

The Traders’ Rim, where the layout and performance of the Channel Anchors make the region vital for speeding commerce and communication among the central galactic states from the Imperium to Shobah. Traders are some of the few people grudgingly accepted into the Free Worlds, making them a tenuous link between that region and the inner galaxy. Prominent landmarks in the Rim include the blue giant Azure, the black hole Point of No Return, and the planetary nebula Mokid’s Eye.

The Ramparts, filled not only with ancient artifacts from the First Ones, but also with the remains of several civilizations that died out before contact with others.

The Sea of Relics, a span with a high proportion of Elder artifacts – many of them still functioning, such as the cryptic information repository at Bastion. Radiation from the active jets of The Pillar keep this region relatively uninhabited. The Burial Grounds, on the other hand, collects fragmented wrecks of Archaic constructs after gravitational tides and cosmic radiation have weathered and broken them down.

The Well of Ghosts, a devastated region scattered with burned worlds and detritus from the Amseile-Shobah wars. It stands as a monument to the terrible power of starflyers’ weapons.

Not all peoples of the galaxy are rooted to a location. The Waygehn had the misfortune of evolving close to the end of their star’s life, and are now spread throughout the Axiom Republic, Traders’ Rim, Imperium of the Triumvirate, and Amseile to form their own political super-entity. Many Waygehn located functional-but-inert relics and retrofitted their own systems onto the ancient hardware to form great arkships and wandering space stations.
