| Component Systems | 8 stellar systems were included in this small empire before its disappearance. The brightest star in this volume is HIP 18608, Fragan Prime, a GV5 star. 205.4 ly from Sol, in Camelopardalis. Fragan Prime has 5 planets, including HIP 18608 d, also known as Rholandi, a lifeless Gaian world. YTS 4425-989-12, also known as Jati. Jati has 3 planets, including Hulos, a subneptunian world. Six other systems were part of this small empire, including three binary stars; mostly M and K dwarf stars: YTS 4428-920-667, YTS 4428-31-700A+B, YTS 4425-30-443A+B, YTS 4428-20-667 A+B, YTS 4425-70-001 and YTS 4420-444-871 |
History
A joint colonisation fleet built by Integrated Nanosystems and Kolonykorp left Federation space in 1744-1748 AT, bound for HIP 18608, with the aim of colonising the terrestrial worlds in that system (with the option of expanding to several other promising star systems near to that location). The fleet of sixteen craft would arrive in 2120-2124 AT, and were equipped with (then state-of-the-art) fabricator tech and biotech capabilities. No transapient entities accompanied them at this time. Although the fleet sent comprehensive status updates for the first hundred years or so, these updates carried minimal information after that time. The craft could still be seen using telescopic interferometry for the rest of the voyage, but for some reason they were no longer interested in communication with the rest of the Terragen Sphere.Over the next thousand years, telescopic observations confirmed that the colonists were successful in building orbital habitats around the target star, and later, in seven other systems in that vicinity. A number of different types of habitat were constructed, suggesting that some cultural divergence had occurred, but no further communications were received. A few structures were constructed on the lifeless terrestrial world HIP 18608 d, but these were difficult to observe because of atmospheric conditions.
During this period three interstellar craft from other systems ventured to these worlds to check on the progress of the colonists, but each craft ceased to transmit data shortly after arrival. Although suspicions were raised by this failure to communicate, the craft were observed to be fully functional afterwards, and no sign of conflict was apparent. The last ship to arrive, the Coresus in 2399, sent the message 'We are unharmed and content. Further messages are unnecessary. Please do not try to contact us until we give permission'.
The newly emerging Solar Dominion declared that these worlds were off-limits, due to the apparently voluntary cessation of contact by the locals. This small group of worlds became known as the Fragan Sphere, from a word in Old Scansolarian that means 'One who poses riddles'. Several Solarian systems in Cameleopardis began to monitor these so-called 'restricted' worlds, in case they posed any threat or developed new and unusual behaviours. However, the Fragan worlds appear to be stagnating, and after 2600 the Sphere stopped expanding. Over the next 200 years very few new habitats where built, and then apparently activity in the Sphere began to decline.
Infrared emissions from the habitats in these systems began to fade, and some habitats were apparently abandoned altogether. As the activity in these systems reduced, so did interest in remote observation. The first Yu-Tang Survey expansion was in full swing, and telescopic observations of potential colony systems further afield took priority over watching the slow decline of the Fragan worlds. Some observers considered that the apparent decline was an illusion, and in fact the population of the Fragan worlds were migrating into a virtual existence; but even a virtual civilisation consumes energy, and emits waste heat, but there was little evidence of this.
By 2900 a significant number of habitats had been abandoned, and some were starting to tumble. Around YTS 4428-20-667 a Kessler cascade event occurred, destroying many of the habitats, and the rest were deserted shortly after. The process of depopulation in the Fragan Sphere was well-ordered, and as habitats were depopulated the remaining people cleaned them out and removed everything useful. In the end the population was concentrated to a few centers, and by 3380 waste heat emissions from these locations had disappeared. A number of antimatter detonations in that year may have marked the final destruction of their culture.
The Third Yu-Tang expansion finally sent a small fleet of survey vessels (which arrived in 3412) to investigate the disappearance of the Fragan culture, and to search for survivors, but none were found. From this moment on, the Fragan Sphere became a subject for archaeological research.
Remaining Evidence of the Fragan Sphere
There are no known surviving descendants from the Fragans, although the Hyl Op of Ghane III show some suggestive genomic similarities. It is regarded as possible that a Fragan expedition may have reached the Ghane system, but there are no historical records of any such event (which is not unlikely, since the Hyl Op were undergoing their civil wars during the speculated period, and the era of the diver princes afterwards erased much of the remaining historical archives). However no interstellar spacecraft were observed leaving the Fragan Sphere towards Ghane III, (or indeed in any other direction).The disappearance of the Fragans poses many questions. What could change the dynamics of an interstellar culture so totally? Why did the last Fragans wipe out the remnants of the Empire? One explanation could have been some widespread infertility problem, such as the loss of control over encrypted genomes making every individual unable to mate with anybody else. But the technologically advanced Fragans should have been able to solve this, at worst by cloning. Also, only 12% of the genomes sequenced actually show signs of encrypted genes.
The spread of a nihilistic or devolutionary ideology or religion has also been suggested, but does not seem to fit the orderly retreat. The retreat does not appear to have been deliberately anti-archaeological until at the very end, rather a simple and rational reclamation of unused resources. Momuless researchers have advanced the theory that the Fragans were plagued by some kind of conspiracy theory, cultural guilt or shame, which undermined their empire. Another possibility is an external or internal threat, such as memetic warfare or a subtle economic virus.
One theory, very popular in the 7600-7900 period, was that the Fragans, for some reason, had left, likely in the direction of the Perseus Arm. If they had built colony ships and embarked on them in an orderly fashion, then the disappearance could be explained, at least partly (the reason for emigration of course remains unsolved). The lack of shipyards could be explained by re-use of the materials. However, no ships were observed leaving the Sphere during this period, and no trace of Fragan colonies beyond the Sphere has ever been found.
Fragan technology was largely based on biotechnology, using centralized bioforges. These facilities were used for recycling unused matter, which is another reason so little finds have been found except for the matter management facilities themselves, often major structures clad in highly resilient bone-like surfaces.
The biological environment was handled by subsapient genetically-engineered organisms. Some of these species have survived as mummified tissue, which can be lazurogened. One species, the Fragan helpermonkey, has been subsequently provolved and currently make up the majority of inhabitants at Hulos and Rholandi. Many of the other worlds are home to the Momuless, a virtual a-life culture dedicated to archaeology and other forms of investigative inquiry.
The Fragans appear to have consistently stored all their information on active optomagnetic media, readable by their modified anatomy, but decaying over time if not refreshed. This has made Fragan information extremely scarce, as practically none of the stores have survived. Even with nanoscale reconstruction the media are nearly useless due to the coding systems and unknown data formats.

Cultures in the Fragan Sphere
From style analysis the Empire appears to have encompassed at least three major cultures, possibly many more. Initially they have been called the Angulars, Delayers and Typographers. They show enough similarities to suggest that the cultures were closely linked, possibly different expressions of an underlying central Fragan culture. The technological and social consistency supports this.The Angular culture was dominated by highly angular and linear art, architecture and design. It encompasses 43% of all known sites, and may have been dominant. Given the architecture and infrastructure designs, archaeologists have reached a consensus that it was likely a highly centralized, hierarchical culture based on small groups of 20-30 persons, perhaps extended families or work teams.
The Delayer culture was distinguished by their use of delay circuits in surviving electronics, the only major deviation from standard Fragan technology. It encompasses 31% of all known sites. The significance of the delay circuit remains controversial, but many pictorial descriptions of its function have been uncovered in Delayer cities. Possibly the Delay circuits were used to handicap non-biological sophonts such as aioids and vecs, an indication that these cultures were deeply paranoid.

Fragan art was apparently never figurative, which suggest some radical shift in culture or cognition from most other human clades. The structures of the art-like objects imply that some of the Gestalt psychology was also altered, leading to different clustering and grouping preferences.
The lack of advanced artificial intelligence is curious. While some electronics found imply at least superturing AI, no functioning AI or high-order AI hardware has been found. There are also very few vec bodies. One explanation could be that the AIs were highly centralized, possibly making up the government. Another is that the Fragans were descended from paranoid AI-sceptics that limited the use of AI, despite the disadvantages. Some archaeologists have suggested that this dearth of artificial intelligence contributed to their fall, but there is only indirect evidence for this idea.
The Fragans remain one of the major enigmas of the rimwards Orion Arm. They will doubtless pose riddles for millennia to come.
