Siebenelle is a hypothesized quasi-stable region within the Local Cosmos located about 17 million light years from the center of it. Contained within the region is an ultra-diffuse collection of stars, dust, and gas with a total mass of about 1,900,000 M☉. Despite this sparseness, exactly one sapient species was able to evolve in the region. Evolving an untold number of years in the past, this species, known as The Seekers, would come to dominate the region. The Seekers have numerous descendant species scattered across the Local Cosmos as they engaged in a mass exodus out of Siebenelle due to an unmanageable collapse in the region's laws of physics analogous to Vacuum Decay.
Siebenelle is no longer habitable with the most recent information from the region, over 100,000 years old, stating that the entire region had succumbed to a breakdown in local physical laws. While there is a chance that this breakdown could occur within the wider Local Cosmos, this is unlikely.
In 18,043 CE, scientists hailing from Erstes Konsortium identified numerous anomalously stable regions of space located so far away that conventional cosmic models would call them impossible. Most of these regions were discovered as small novae formed within them. After developing a new model to account for these regions, explained by the rotation of the Local Cosmos that was only apparent while looking at them, the scientists developed a naming scheme for them.
The region today known as Siebenelle was not discovered by these scientists nor was there any indication that it existed with not even an indication of gravitational influence on nearby groups. When Jewel's Remnant first came to Via Aylathiya in 60,391 CE, their trajectory pointed to what was previously believed to be an empty region of space near the edge of the Local Cosmos. This region, whose existence was only speculative, would be called "7-L." After the Inheritance War began in 60,393 CE, common usage of the phrase "7-L" would morph the into word "Siebenelle." After peaceful relations in Via Aylathiya were attained, the Remnant's preferred title, "Seekya," would not be adopted.
Siebenelle is believed to have formed in the same way as the Local Cosmos has. As an ultra-diffuse region of space with barely one million stars, most of the stars that had formed 13 billion years ago would exist up to the destruction of Siebenelle. Very few planets would form in a region as diffuse as Siebenelle and even fewer habitable worlds would form.
The home world of The Seekers formed sometime around 10 Gya around a small M-type red dwarf. This world is never referred to in any database carried by the modern Jewel's Remnant, their successor. What's more is that it is not clear how a habitable world would be able to form in Siebenelle and remain stable enough to produce a proper civilization.
The Seekers likely emerged about 2.3 million years before the present day during a period of relative stability within the region. While assumed that they formed via typical Darwinian means, there are no records of any other species they would have evolved from. Researchers within the Jewels' Remnant were surprised to learn that non-sapient life forms existed. They do not have a theory or even a credible hypothesis as to the Seeker's origins besides some rough estimates for dates.
Properties & Hypothesized Properties
Due to Siebenelle's proximity to the Void of Creation, the region would be highly unstable, far more so than much of the other regions like it. Siebenelle was likely greatly influenced by the gravity of neighboring bodies, creating cyclical periods of stability and instability as the laws of physics would become more or less fluid. The most recent of these interactions, taking place over one billion years ago, would have set Seibenelle on a trajectory straight into the Void of Creation, permanently destabilizing its physical laws.
Siebenelle's subtly destabilized laws likely did not have much of an effect on the day to day lives of macroscopic organisms. The difference was so minute that only certain quantum interactions would play out slightly differently, interactions that rarely took place within biological organisms in the first place. The laws did, however, have an effect on high technology. One example is the machine known as the Ultima Ratio. This device, in short, takes advantage of the slightly turbulent physics within Siebenelle to destabilize space-time. This destabilized space-time would have allowed for advanced SICTIRIAD travel to take place as well as act as an effective weapon. A consequence of the device returning to stabilized space is a sort of "incompatibility" contained within it, causing it to be quite disagreeable at best and having eldritch effects at worse. Most ships, weapons, and devices carried by Jewel's Remnant have this property. The phenomenon is called "Jewel's Touch" and seemingly only effects high technology. Low technology that does not deal with quantum effects is exempt even if it was created in Siebenelle.
