The Triffid Nebula (not to be confused with the nebula in the Milky Way Galaxy of the same name) is a star-forming region which was once part of the Phradox Galaxy. Around 6-7 billion years ago, a smaller galaxy fell into the gravitational well of the Phradox Galaxy and was subsequently absorbed into the galaxy's larger mass. A huge quantity of debris from this collision formed the "Great Ecliptic", a ring of gas and dust that orbits the galactic center at a steep incline above the galactic plane.

The Triffid Nebula itself is one of the countless smaller dust clouds hurled away from the galaxy by the immense tidal forces of the galaxy's mass. It began forming stars around 5 billion years ago, and due to the nebula's richness in heavy elements, gave rise to numerous planetary systems. These systems are almost unreachable to the inhabitants of the rest of the Gigaquadrant, and may only be accessed by a network of wormholes that entangle the nebula with other massive bodies, such as galaxies.

The majority of the nebula is controlled by the Ecumene, a civilization native to one of the nebula's oldest stars, Arachosia. The Ecumene has half-heartedly colonized the other planetary systems in the region, but due to the abundance of traversable wormholes connecting the nebula to other regions, the comparatively expensive method of colonizing these stars has been largely left to those who are particularly wealthy, bold, and sufficiently bored.

History Edit

True history in the Triffid Nebula began around a million years ago when the first colonists arrived from other galaxies, primarily the Phradox Galaxy, which was the nearest major galaxy. The interconnected network of wormholes that spanned this vast distance was easily exploited by Primals - an ancient galaxy-spanning empire that controlled the Phradox Galaxy. These were the first civilization in that galaxy since the Core Federation which were able to thread wormholes using control of degenerate and strange matter, and thus colonized the Triffid Nebula primarily by this means. However, their mastery of various forms of exotic and strange matter meant that the wormholes they fashioned were very unlikely to decay or collapse, except on cosmic time scales.

This extremely stable set of connections meant that travel between these two bodies meant that later civilizations would have a significantly easier time traversing this distance than if they were made to develop the technology on their own. This spurred several waves of tentative colonization by the later civilizations of the Phradox, but these were ultimately never successful for one reason or another. The Triffids are believed to have originated in the Phradox Galaxy and then were transplanted or migrated to the nebula itself a few hundred-thousand years ago.

The last 100,000 years have seen a relative explosion of life in this largely dormant corner of space. All of the following terminology is derived from the language of the Ecumene, and not from the natives themselves. The "Leviathans", an archaic race of intelligent starships, migrate regularly to the nebula in order to "feed" on the various exotic matter derivatives present in the Charybdis Gulf (see below). The "Astrokhans" - a widely dispersed and decentralized group of cultures - dominate large parts of the nebula due to their effective style of conquest ,which prioritizes shock and awe in order to cow less developed species into voluntary submission. The "Sentinels" are a harmonious species of artificial lifeforms manufactured by some more ancient civilization in order to protect life in the universe - a mantle they pursue with almost comical zeal. "Changelings" are another widespread form of life; these are telepathic fluid-based shapeshifting beings that generally do not communicate with other cultures except through means of deception.

The most recent, but unquestioningly most dominant, civilization of the nebula is the Ecumene, which began a half-hearted effort to colonize the center of the nebula. However, most of these colonies are centrally governed and exploited for resources rather than any concerted effort at colonial expansion. As a result, conflicts are rare, and when they do occur, they are typically brief and relatively bloodless.

The sole exception to this is the War of the Polemarchs during which a migratory clan of the Astrokhans attempted to conquer the Ecumenical home system, Arachosia. This lasted several decades and the ensuing bloodshed led eventually to a final crusade by the emerging faction of elementals within the Ecumene who swore an oath of vengeance against those who ravaged their homes. A tense peace has since been enforced, and many higher intelligences are cautiously viewing the situation with a mix of boredom and dread.

Colonial Civilizations Edit

These civilizations are what may be considered "traditional societies". They live primarily on high-gravity planets and environments that simulate high-gravity planets (such as O'Neill cylinders and Stanford tori). Most such civilizations are necessarily pre-singularity and exist primarily as Type I or Type II states. Such civilizations are necessarily limited in their scope due to their relatively sedentary nature, and are much more likely to be driven to extinction by cosmic or essential phenomena.

  • Unified One Earth Commonwealth

  • Imperial Heterarchy of the Stars

Vagrant Civilizations Edit

These civilizations are colloquially referred to as "spacers", due to their populations being restricted to mobile, artificial vessels. They are incredibly varied in their complexity. They include completely organic sophonts such as the astrokhans and bio-sentinels, whom have forsaken planetary life, completely artificial life such as the leviathans which are effectively sapient spacecraft, and essential life that travels in extra dimensions like the sequelavorae, which can freely travel through space and time.
