Welcome to the Galactic Crucibles setting, the primary location in the Omniverse Nexus for science fiction and space operas. This guide is an overview of what Galactic Crucibles is and how to get involved with it.

Galactic Crucibles, abbreviated as GC, is the debut setting of the Omniverse Nexus. It features the Crucible Galaxy and its satellite galaxies in a self-contained universe completely distinct from our own. No location in Galactic Crucibles is present in our own universe, as with any construct be it: civilizations, technology, or individuals.

The main location, the Crucible Galaxy, is largely built upon the civilizations that came before their time. Galactic seeding and world builders long gone are largely responsible for the shape the Crucible Galaxy is currently in. In-line with its name, the Crucible Galaxy’s story is heavily reliant on the interactions, friendly or hostile, between the populace that call it home.

The infrastructure Galactic Crucibles supports is limited only to what you are willing to write. All genres and characters from any walk of life are welcome. Restrictions do apply in some circumstances: excessive profanity, heavy gore, and other adult themes are taken on a case-by-case basis. For more information, please take a moment to look over the Omniverse Nexus rules.

User:Suppy is the Loremaster for Galactic Crucibles. As with other settings in the Nexus, bear in mind that the Loremaster has the final say on creative decisions and direction of content. Additionally, the setting expert User:Krayfishkarl will be able to introduce you to the Crucible Galaxy and answer any questions you may have. The setting expert’s knowledgeability may vary, and they may direct you to another user if your question falls outside what they know.

Portal pages

(map coming soon!)

Galactic Crucibles' history is divided into multiple eras and large scale story arcs that affect the entire setting. While it is not necessary to have your creations directly involved with these grand storylines, these distinct eras can serve as backdrops to assist with your worldbuilding endeavours. It is up to you how much of these story elements you wish to incorporate so long as your story can still reasonably take place within canon. The links below lead to portal pages that contain more information on the eras of GC. The Second Galactic Senate era was the first to be written and developed, but you may freely choose whichever era you like to explore and write for.

  • Empire of Arckas - The Empire of Arckas was a Kardashev Type III civilization that created megastructures for the art. After nearly accelerating the heat death of the universe, they left to explore the multiverse.
  • Omni - The Omni Empire ruled the Crucible Galaxy for 5 million years, expanding upon many of the ygsium-based jumpgates derived from Arckasian technology. The Omni Empire was destroyed by the Buyuk Empire, servants of a malevolent Matrioshka brain known as LUCIS.
  • First Galactic Senate - The Karnasaur Meritocratic Federation challenged the Buyuk Empire’s control over the Galactic Core. After establishing a ceasefire, the KMF would collaborate with other spacefaring species to form the First Galactic Senate. However, their civilization fell when a sterility plague infected many spacefaring species across the galaxy.
  • Buyuk Wars - With the First Galactic Senate gone, the Buyuk asserted their dominance once more and prepared for the eventual return of LUCIS. Many other species waged war against them for survival.
  • Second Galactic Senate - At the Battle of Domum Regimen, an Arckasian AI named Na’zrah was discovered. With the collaborations of many species across the galaxy, an alliance was formed to defeat the Buyuk in a chain of events leading to the formation of the Second Galactic Senate. After a golden age of 100 years, the Senate unfortunately fell to galactic civil war. Not only that, LUCIS returned along with a new enemy known as the Anathema.
  • Post-Anathema - The aftermath of the Anathema invasion led to a dark period where civilization was far and few between. Once great superpowers had fallen, but new ones were sure to take their place.



  • GC takes place across a single, consistent canon with no defined present day. Articles are required to be in past tense. Stories do not have this requirement, but past tense is still encouraged.
  • The general scope of GC is a single galaxy and its satellites. Galaxies are enormous so there’s plenty of room to add content. It is best to add creations that are in close proximity to existing content unless there’s a really good reason not to.
  • Galactic Crucibles takes place in its own separate universe from the real world, so humans and planet Earth do not exist. However, there do exist humanoid species. This choice was made so as to not take away attention from all the aliens while still allowing characters relatable to the audience.
  • Astronomy terms that refer to Earth-derived terminology are allowed. This is to make articles more readable and consistent with real world astronomy.
  • The sci-fi is grounded but theoretical ideas are welcomed and encouraged. GC is meant to be scientifically plausible, but just remember that good storytelling and good suspension of disbelief come first. Be sure to consult the loremaster or setting expert before adding new theoretical technologies that could affect the storylines of other user creations.
  • The GC universe is massive and thus, not every location will have content just yet. Treat them as you would a Schrodinger’s Cat scenario. These blank areas are considered non-existent until something is written there.
  • Key to GC is the idea that any sufficiently advanced technology is indistinguishable from magic. There is no true magic in Galactic Crucibles, but there are certainly technologies and phenomenae that come very close to it.

Article creation

  • First time users should create a pitch of their ideas before writing any articles or stories. See "How to get started" for more information.
  • Star systems and planets should all get their own articles, especially the former. As a result, be mindful that as your spacefaring civilization increases in size, you’ll need to make articles about each star system. They can just be stubs for the time being, but the existence of these articles helps to convey the scope of the setting.
  • The main coordinate system in place is as follows: galactic sector -> star cluster or nebula -> star system.
  • The Battle of Domum Regimen, a major event marking the start of the Second Galactic Senate era, is used as an out of universe timekeeping system. Events are determined as either BDR/ADR (before and after the Battle of Domum Regimen). If you so choose, you may create your own calendar system as long as you specify a conversion system to BDR/ADR.
  • Don’t be afraid to make your aliens and cultures truly bizarre. Galactic Crucibles is all about challenging the limits of what is possible.

How to get started

New writers for the setting will need to create a pitch that details their immediate plans for Galactic Crucibles. This can be a storyline, article or something else. However, the best way to get started in Galactic Crucibles is to create your own species and its home star system. See if you can come up with a homeworld for your species to inhabit, then design them based on what sort of adaptations they might need to survive there.

You should also specify what form of FTL, if any, that they use. It is up to you whether you want to use the Arckasians, the Omni, the Karnasaurs or any ancient civilization in your species’ backstory. These previous civilizations facilitate the overcoming of the Fermi paradox, but you are more than welcome to make something that developed independently from them.

After you’ve created your species and star system, decide on where and when they exist. Pick an existing star cluster or create a new one, then place them in one of the galactic sectors in the map above. Once you’ve done that, choose an era to determine who might be around for them to interact with. All of the above information should be compiled into an easily accessible document. You do not need to have the article's final writing in place yet as long as you convey your idea clearly enough.

After your pitch is approved, then you’re free to create as many articles as you like. Just remember that more pitches will be required if your story or creation will have a significant impact on either another user creation or one of the larger scale story arcs

Important articles

Below are some articles worth reading before getting started in Galactic Crucibles. If you have not done so already, it is highly recommended you also read the portal pages for additional background information.
