"On every timeline, in every Universe, the Earth ends catastrophically, and humanity perishes, before full human potential can be achieved." -Cassandra, the Void Engineer
"I'm not okay with that." -Starry, Ancient Engineer of Interdimensional Navigation
A BRIEF PAST HISTORY OF CONVERGENCE
When most Universes were young, a problem arose. People worshiped a great many different Gods, and when they died, those souls would get tangled, lost, languish around the place of their death, or sent to the wrong deity. So a group of Gods got together to build the Pale Realm, a place where souls could rest and lose their worldly connections before returning to the deities of their choosing. Each of the Gods gave a portion of their power to create powerful beings, known as the Ancient Engineers, to build this Realm.
But, several of the Gods realized that if they took control of the Pale Realm, they could route any souls to themselves. And souls, faithful souls, are power to the Gods.
The Ancient Engineers, being parts of these Gods, but not beholden to any one of them, realized this. They didn't want the dead to fall into the hands of any particular god, so they made it so that no god could ever interfere in the Pale Realm. But, having done this, they put themselves at risk. The Ancient Engineers knew that eventually, some clever God would figure out how to either coerce them to "fix" the Pale Realm, or to fix it themselves. They were pursued across the galaxies by the denizens of the Gods. And in this chase, the Ancient Engineers came to believe the problem was even bigger. Some gods, though definitely not all, did not want what was best for their worshipers. A very large percentage of gods were unscrupulous and cruel.
However, the Ancient Engineers had a talent. They had been created to build the Pale Realm, but they could utilize these abilities to build Realms in general. And so they constructed Convergence, the original city of Convergence, floating in space.
But the Gods sent a terrible entity, a malignant, ever-growing terror to consume Convergence. It was called The Dark. And it forced Convergence to flee.
Convergence, the entire city, then came to Earth, an Earth that had been largely de-populated by the plague known as D13. This plague, which made people turn insane in a myriad of horrifying and vicious ways, had caused much of humanity to turn on itself. They were saved only by supernatural creatures, which formed a coalition known as the Consortium, and begin to work both towards a vaccine, and re-building the planet.
But eventually, the Dark found Convergence again, and the city once more fled, transporting itself to an alternate dimension Earth. New Earth, as they called it. Here, Convergence found itself at odds with the corrupted Avalonians, who wished to conquer this New Earth to glean Lumina to fuel their wars. Wars which had, unfortunately, been amped up ridiculously due to the Avalonians having caught D13 before locking themselves away in Avalon. However, with the help of creatures known as the Fomorii, who were also heirs to Avalon, the people of New Earth were able to defeat the Seelie and Unseelie. Unfortunately, as she was dying, Unseelie Queen Mab cursed the city to become a beacon once more to the Dark.
It seemed that there was no escape this time. Convergence was doomed. However, a device known as the Blink Engine was found the abandoned labs of the Ancient Engineer known as Starry. With the help of various entities in the city, and allies that Convergence had been made abroad, portals were opened all over Earth to a place Starry described as, "A Safe Haven When All Hope is Lost" and "Humanity's Hope".
Unfortunately, the Blink Engine was designed only for certain lifeforms, such as humans, to use. It took the power of the Fomorii to re-design some of the races to allow them to safely travel into the next realm.
To understand Fornax, one must understand Starry, the Ancient Engineer.
Nixxa, goddess of the Night Sky, loved the way humanity looked up to her. She saw all the terrible things done to humans in the night, saw them crying, hiding, and lost. Nixxa saw them at their most vulnerable. She had no wish to be a part of the Pale Realm project, but the Gods implored her to contribute. She would be the one most likely to appropriately create something that would help souls navigate the Cosmos and find their way through the Pale Realm and back to their Gods. She finally agreed to participate, but only if she could create her own, special, separate Ancient Engineer. The other Gods had to agree. Nixxa created Pyxis, later known to the world as Starry.
Pyxis inherited Nixxa's love of Earth....to an obsessed fangirl degree. She would visit different timelines, different versions of Earth, and soak up all the culture of each. Often, she would give them a little push, become a muse to an inventor, suggest a new type of paint to an artist, whisper a little about how best to build that pyramid. She was certain, as were many Ancient Engineers, that the creativity, the spirit, the ingenuity of humans would ultimately find a way to defeat and destroy the corrupt Gods. They would prove to be the saviors of all the Realms...someday, when true and full human potential was reached.
And that's when she was told, by the most powerful of all of the Ancient Engineers, Cassandra, that the Earth would always, in every timeline, be destroyed before this happened.
Distraught, Starry came up with a plan. The Earth would always be destroyed.... But what if she could save the humans? She and the other Ancient Engineers implemented a plan to do so with the original Convergence, but Starry was always worried. Wherever the Ancient Engineers were en masse, their enemies would follow. So, eventually, Starry began working on a secret project, alone. Fornax Station.
Fornax Station is a massive structure. Part spaceship, part satellite, Fornax Station would move through the Universe, looking for a suitable planet for humans (some of whom Starry had given refuge on Fornax Station) to live. When Fornax found a potential planet, it would land, samples would be taken, supplies gathered, and either Fornax would stay, or it would lift off and continue the journey. When the final destination was found, Fornax would transform, the outer hull unfolding to provide safe platforms for a New Convergence to be built upon. Much of the ship's structure could easily re-purposed into the initial buildings, or could be used as "feed" for industrial printers.
But, something went wrong. Although Starry would visit Fornax often, via the use of interdimensional portals, making sure the project kept on track, she eventually stopped coming. She disappeared. Then came what is known as "the Crying Times". A rash of calamities occurred. Supplies were short, and systems were failing. Plagues hit Fornax. It was found that someone dumped fuel, which was supposed to last Fornax for millions of years, into space. There was no choice, then, but to land under the knowledge that Fornax would not be able to take off again. The most suitable planet in the area was scouted. Fornax landed and unfolded. And the construction of New Convergence begun.
