The First Wormhole Nexus

Wormholes are detected for the first time

In 1558 AT the Wide Array Exotic Radiation Telescope (500AU baseline) in the SolSys Oort Cloud detected unusual readings from Xi Geminorum (51 ly from Sol, class F5III). These energy and gravitational wave signatures were consistent with the existence of a wormhole in this system. Although the concept of hypothetical wormholes was well-known to cosmologists in this era, none had yet been detected. Since Xi Geminorum was sknown to have been colonised several hundred years earlier by Diamond Belt Ahuman AI entities fleeing from the Solar System, it seemed likely that this wormhole was artificial in origin. Soon similar emissions were found from the stars Ain and Gamma Tauri, both stars in the Hyades open cluster. Observers surmised that these systems were all linked by some kind of wormhole network, which might extend to more stars in that cluster and elsewhere nearby.

An autonomous Explorer-Class probe ship the Carl Sagan was accelerated by Boostbeam to Xi Geminorum and arrived 120 years later, and reported the existence of a highly advanced AI civilization with many curious features. Attempts at closer examination and contact resulted in the destruction of the Carl Sagan by the AIs. This mysterious civilization was given the code name Xi Geminorum AI-1, and presumed hostile.

However, in 1931 AT, all indications of technological activity from the Xi Geminorum AI - 1 Civilization ceased, although the wormhole signatures remained. First Federation observers in the nearby New Callisto system suspected that this civilization had undergone a hyperbolic collapse or even a transaturation ascension, and launched a number of small fly-by probes towards the star. The results confirmed their suspicions. The megastructures associated with this civilisation remained, but there was no signs of activity such as waste heat or drive signatures, and the probes were not molested. The leading theory at the time was that the encounter between the Carl Sagan and the ahuman entities had somehow caused this disappearance event to occur, but the details have never been confirmed.

The Establishment of the Taurus Nexus

The New Callistans lay claim on the territory and began to tool-up for a massive colonization and development initiative. But word had long gotten out, and similar projects were launched from several other systems, including Federation, ex-Federation, and non-Federation.

Over the next three hundred years this network of 25 abandoned wormholes - now called the Taurus Nexus - was investigated and explored. Because the wormholes were all small (ranging from sub-millimeter to 10 meters, with a few nanogauge comm-wormholes) most transit was via nanoscale probes, uploaded mentalities, and microships equipped with engenerator technology. Even so, the Nexus rapidly developed into a hyperpower even more sophisticated than the Federation at its height. Sophonts of all types were attracted to the Nexus, and Transapient research into the still-functioning wormholes helped to advance their understanding of metric engineering considerably. The capital of the Taurus Nexus was established at Corona, Iota Piscium I, at the edge of the Inner Sphere.

After the decline of the First Federation, the Taurus Nexus became its apparent successor, considered by many to be the most powerful interstellar civilization yet created. Science mixed with hedonistic indulgence, libertarianism with aiviser guidance. Investment and technology flowed in from all over known space. Even the rise of the AI Gods elsewhere in the galaxy did not harm the Nexus, although there is no doubt that higher level subversion had a huge effect on local politics, and many bionts, cyborgs, vecs, and superturings clamoured to keep the Nexus free of foreign interference.

The Decline of the Nexus

After studying the abandoned wormholes thoroughly, the transapient combine Vega Geodesics managed to replicate the technology in 2110. Soon, new wormholes were being established throughout the Inner Sphere, and the Taurus Nexus came to seem hopelessly obsolete. From the 2500s onwards the original, small and often unstable wormholes were repaired or replaced by superior versions by weylforges designed by the Lord Of Rays. Foreign intervention and memetic engineering increasingly harried what had once been the jewel of the galaxy. In 3263 the "Inner Sector" attempted to break free in order to become part of the NoCoZo, leading to the First Consolidation War, one of the bloodiest early wars known. The surrounding empires annexed many of the worlds, and in 3400 there was not a trace of the Nexus.
