"Charybdis, The Swirling Beauty, known by many names. To many, this tiny galaxy is the utopia of the universe, and to the unlucky few, a dystopia. Hiding in it's swirling clouds hides one of the richest and diverse populations in all the universe" - Anonymous traveler


The Charybdis Galaxy is a slightly larger than average galaxy located in an extremely close orbit around Cosmoria. Despite being Cosmoria's only satellite, Charybdis is said to be such a magnificent galaxy that it attracts a high amount of tourism in Cosmoria and of course Charybdis itself. This close orbit results in one of the most attractive views both during the day, and night on most worlds in Cosmoria.

It is theorized that many old, long-extinct civilizations in Cosmoria used the Charybdis Galaxy as beacon of navigation, both on land and in space. This, of course, has led to many explorations trips to Charybdis from Cosmoria undertaken by a few civilization. This is one of the main reasons as to why Charybdis is one of the most populated galaxies in the Local Universe, which nearly eighty five percent of all the systems having at least a single populated world. This obviously states that all of the Charybdis Galaxy has been explored and successfully mapped. Many species themselves have migrated to Chrarybdis for protection against Cosmoria turning into a quasar.

The interstellar medium of Charybdis is the reason that Charybdis can be so abundant in life, yet close to a massive and deadly quasar. The interstellar medium essentially deflects the radation back to Cosmoria. This in turn is creating an effect where Charybdis seems to be generating a high amount of radiation radiation, however, it is just radiation bouncing back.

Charybdis was once one of the most decentralized areas in the universe, before the great reformation in 94,624, a large-scale event during which all of the thousands of nations present in Charybbdis united into two even larger confederacies. After colonizing most of the galaxy, with nowhere to expand, these two confederacies have begun to enrichen their colonized systems, known as the great enrichening. This period of the galaxy is still in progress, with many megastructures being constructed each month, and hundreds of worlds populated every single week.

Charybdis has given birth to many thousands of sapient species, some which have fallen and destroyed themselves, and some have propelled themselves toward being the most influential species in the galaxy. The galaxy is so abundant in life that around ninety percent of star systems have unicellular life, and one in five systems has multicellular life, be it tiny and insignificant hidden deep in the seas, or thriving across the landscape of an unimaginably alien moon. This has led to Charybdis being the most life-filled galaxy in the entire known universe.

Humans first arrived in Charybdis in 90,426, and in less than ten thousand years, have made themselves one of the most widespread and influential species in the galaxy. As highly expansionist species, Humans started settling world after world, eventually rising as high as helping to form the United Commonwealth of Hyendera during the great reformation.

The name of Charybdis is derived from the mispronunciation of the ancient phrases of Char and Bidia, from an ancient Aquelis language called Old Aquelianese. Char is roughly translated into the word "swirly" and Bidia likely means "beauty".


The Charybdis Galaxy is made up of several different regions that have been separated into culturally and politically agreed upon sectors. A system of directions is also in place, with coreward, rimward, spinward, and antispinward being the most common.













The Charybdis Galaxy currently has 6,542 confirmed and well-documented nebulae. Most of them are concentrated in the two swirls of Hypenera and Charendia. While fairly rare, many extragalactic nebulae exist, orbiting around Charybdis acting as a kind of mini dwarf galaxies. These nebulae are all designated by the Charybdis Nebulan Realm (CNR) catalogue, based on their order of discovery by Humans.

The nebulae all vary in size, hue and amount of stars. Some diffuse nebulae can be red and have tens of life-filled worlds, while a green planetary nebula could have no planets at all. The nebulae of Charybdis are one of the most colonized areas, valued by their appearance and their interstellar gas that is regularly harvested by advanced machines. Many interstellar corporations have formed around harvesting the nebulae gasses. Sometimes in these nebulae, nature can do the impossible, and give life to large spacefaring extremophiles. A major example are the sapient and widespread Nebulon Whales in the Caerulean Cave Nebula.


While clusters are not as prevalent and widespread as the nebulae of the Charybdis Galaxy, they are still major hubs of population of economy. Many clusters actually exist in the nebulae of Charybdis, while some can happen to be thousands of light years from a nebula. Catalogued by the Charybdis Cluster Catalogue (CGG), there are 3.562 officially recognized and mapped star clusters outside of the many nebulae. These fall into two general categories, which are open clusters, made of up to a few thousand stars that were formed from the same giant molecular cloud and have roughly the same age, and globular clusters, which are star clusters very tightly bound by gravity, giving them their spherical shapes and high concentrations of stars toward their centers. Nearly two and a half star clusters are actually inside the galaxy, while the rest are found orbiting the Charybdis Galaxy itself.

These star clusters are major centers of economy, often being a part of the most major hyperspace routes in the Charybdis Galaxy, such as the Kyanian Way or the Evera-Terra Path. Due to their high concentration of stars, the star clusters of the Charybdis Galaxy have so high populations that they rival entire sectors of the cosmos.

Stellar Objects

Stellar Remnants



Faresae are anomalous stars mostly present in Charybdis, Cosmoria and Flower galaxies, with some exceptions in other galaxies. These stars usually seem to abide by the laws of physics, however, have various notable anomalous effects.

Aroteon Stars

Aroteon Stars are a type of Faresae with wildly varying temperatures and chemical compositions in various portions of the star, creating their distinctive rainbow appearance. Aroteon Stars only form in absence of Chromastrodium, an extremely high-mass element which is very good at refracting light into very specific wavelengths, which differ for each isotope.


The Udherae are a collection of nebulae and clusters that have anomalous properties. The Udherae-type anomalies have mainly been detected in the Charybdis Galaxy, with some exceptions documented in the Cosmoria Galaxy.

Tempus Nebulae

Tempus Nebulae are a highly anomalous type of Udherae, a set of anomalous nebulae in Charybdis and Cosmoria. Their single anomalous property is that when one is inside a Tempus Nebula, the flow of time can increase, or decrease randomly. This effect only comes into existence if a sapient being enters, no other non-intelligent lifeforms can trigger this anomalous property. This effect is theorized to be tied to the mysterious realm of Aeterna Caligne.


Prehistoric Era


Charybdis started it's formation around 13 billion years ago, a period in time during which many of the most major and influential galaxies had began to from in the Local Universe, such as Via Sagittaria, Flower amongst many more, a small number of which of which do not even exist anymore, lost to the eternal flow of time. During many millions of years, Charybdis started to grow into a spiral shape, far different from the near-irregular galaxy it used to look like during it's past, completing it's formation.

It was a chaotic period for Charybdis, infinitely littered with the remains from the time of early formation. Over the course of time, the first planets started to form in the accretion disks of some of the very first stars in Charybdis itself. Naturally, process itself repeated itself all across the entire known universe, with absolutely no expectations anymore. Some planets were too small and got captured as moons around larger and more massive planets, and some would be even thrown out of their respective systems by the most massive of planets. All of these planets would suffer from the same depressing fate, as the planet's parent star started getting tinier and tinier by the day, until eventually it was one of the many tiny dots cluttering up the sky.

First Appearance of Life

Life, being a constant in the universe, and having abilities of extreme adaptation to survive on nearly every environment scattered about the universe, started evolving from simple organic compounds all across the many planets and moons. The very first life in Charybdis, and the entire universe itself was purely microbial, being tremendously small in size. Most of these lifeforms would be genetically able to replicate themselves into two individuals. Each time when replicated, the individual would have tiny changes, which caused evolution to begin all across the entire universe. Smaller lifeforms would evolve into bigger ones, which each time when reproduced started getting more complex.

This life would evolve into more and more intelligent organisms, until the mostly dead at the time Charybdis galaxy saw the rise of it's first sapient species. Dubbed the Antecedents, this species was born before any other, during a chaotic era when Charybdis was littered with supernovae, high-radiation environments and space debris crashing on many worlds. So little is known about the Antecedent bspecies, that it is theoretically impossible to determine the world the species was native to, their culture, technology, appearance and much more. Only the most basic of knowledge has been unlocked, as nearly no knowledge from that era has survived for such an infinitely long time. Only a single ruin of the Antecedents has survived, situated in interstellar space near the Lochia System of the Karasia region. What is certain, however, is that the Antecedents went extinct by their own creations. A widely accepted theory suggests that some kind of AI of Antecedent origin turned of them, thus eliminating the entire species. The Antecendets is the only species that scientists know of in the Prehistoric Era.

Charybdis as a field galaxy

Charybdis would, over time would become a field galaxy, anomalously accelerating at a quarter of the speed of light far away from other galaxies near it, the closest of which was the Rodaun Galaxy at that time. In just a hundred million years, Charybdis was so far from any other galaxies that they couldn't be seen in the night sky with naked eyes, outside of the currently defined Local Universe. It would remain so until it collided with Galaxy 74, and changed it's course toward the Local Universe, accelerating at a far slower speed than before.
