The Well of Finistelle is the first element of the Pale Path discovered by human explorers. This paracausal megastructure was found five lightyears away from Finistelle Station, seven thousand lightyears above the galactic plane. It was presumably built by the same civilisation that assembled the Pale Path, though it bears the signs of more recent engineering.
The Well is a megastructure that assumes the shape of a perfectly immobile, hollow needle, three hundred thousand kilometres long and five hundred meters wide. It is made of a single compound that has yet to be identified, but seems to straddle the line between organic material and metal, a common property of transbiological technology. Originally white, this compound turns to grey, then black as it degrades with time and, presumably, exposure to cosmic radiation. The core structure of the Well is assumed to be about five to fifteen billion years old. Only one third of the megastructure exists in our own three-dimensional universe, while the rest seems to be physically present in different, self-contained dimensions. This makes the Well the largest example of trans-dimensional architecture known in the galaxy. Though we can only speculate about its purpose, it is assumed that the Finistelle Well serves two main functions. It anchors the first dimensional bubbles of the Pale Path and connects them with our own universe.
As is the case with most technological remnants of the Pale Path's builders, the Finistelle Well is in an advanced state of disrepair. It is unknow why the structure of the Well is weakened to such a dramatic extent, but the latest Starmoth Initiative research suggests that the entire structure had structural faults to begin with, owing to a miscalculation in assessing the actual strain a trans-dimensional pin is submitted to. While surprising for such a technologically advanced civilisation, this error can be understood if one takes into account the fact that the Pale Path was probably an experimental concept, perhaps even a hobby project, that may not have received all the care it should have. While the Well isn't expected to fall apart before another billion years, the slow dereliction of its structure results in a thick cloud of dust accumulating at the Pale Path-facing entrance of the pin under dimensional forces. This greatly complicates operations in and around the Finistelle Well.
Humankind is far from the first species to discover the Well, and the Milky Way-facing part of the megastructure is littered with shipwrecks, ancient research stations and space debris. Most of them haven't fared much better than the Well itself and are but empty, featureless hulks littered with micrometeorites impacts. Almost a hundred thousand Sequence wrecks have been identified inside and around the Well, the result of a massive battle that happened roughly ten million years ago, when the interstellar empire tried to breach the Pale Path in order to conduct a crusade against its creators. It is unknown whether this is how the Sequence gained entry to the Path, or if they found another gate, but they appeared to have used concentrated UREB strikes against the outer armour of the Well. While it eradicated whatever defence systems the megastructure might have possessed, it also greatly compromised its structural elements, shortening its life by a good billion years.
Navigating inside the Well is rather difficult due to the sheer density of debris, dust and wrecks alongside the spine of the pin. Geometry drive usage is strictly forbidden inside the Well, where dimensional interference greatly reduces accuracy and makes translations inflict grievous damage on the weakened megastructure. While Azur Effect drives are not affected in the same way, their effects on the Well are even more critical -- it is expected that repeated Azur translations near the base of the megastructure could outright shatter it. In order to travel up and down the Finistelle Well, the Starmoth Initiative has deployed two space elevator-like cables running from one end of the Well to the other. Alongside these cables have been installed two repurposed Mansa Mussa cargo ships, Occident Express and Trans-Europe Express. Stripped of their engines, these vessels are used as trains, running along the cables on their own nuclear power to ferry passengers and cargo from Finistelle Station, at the Milky Way-facing end of the Well and Finistelle Terminus, near the Pale Path's entrance. Between the endless darkness and the sights of million year old skeletons hanging in the void, travelling inside the Finistelle Well is both mundane and terrifying.
At the very bottom of the Well, the second waystation enables access to a smaller tunnel that itself gives way to a section of liminal space, the buffer area between the dimensional bubbles of the Pale Path. From there, and with a bit of luck and madness, most of the contained dimensions are accessible.

Subspace anomalies detected upon translation in system: geometry drive reports false alarm (class 01 - unknown cause) from FTL

strontium, holmium, niobium, scandium, yttrium, caesium, uranium and
other elements belonging to lanthanides. Other exotic elements are
present, including actinides such as neptunium. Spectral characteristics
are only partially coherent with Ap and Bp type stars. Comparison to
surveyed stars did not return any perfect matches, however several
partial spectral similarities have been noted with Sequence-occupied
stars, as well as Finistelle's veil-stars. Closer inspection
of the star revealed local variations in magnetic field and convection
cycles beneath the star surface, hinting at the presence of a nascent

a closer orbital pass (within 300,000 kilometers of the star), on-board
equipment started reporting temporal anomalies, with both atomic and
crystalline clocks signalling chronological deviations way beyond
expected parameters. Furthermore, external ablative armor sensors
reported numerous nanometric impacts during the low pass. Both
concentration and speed did not match the primary hypothesis of
planetary or asteroid debris. Two probes sent in a lower orbit reported
even more extreme temporal deviation, with on-board clocks ending up
entirely unsynchronized after fifty-five seconds. Complete loss of
communications following critical OS corruption occurred after one
hundred and twenty-two minutes. Ultimate value for temporal dilation was
-375% and falling. Strangely enough, local temporal dilation did not seem to trigger any significant redshift effect, which is characteristic of a paracausal event.
Conclusion: very low rotation period is due to extreme local time dilation.
of collected debris revealed an unusual concentration of rare or even
unknown ultra-heavy elements at the very edges of the periodic table.
Orbital dispersion appeared compatible with slow orbital decay of a vast
amount of shattered debris. Complete mass of material is estimated to
be anywhere between one to three Earth masses, with temporal deviations
ensuring a way lower decay rate than expected. Prospective
reconstruction of debris field hints at the presence of at least two
ring-like structures circling the star. Interestingly enough,
micrometeorite impact analysis on high orbit debris showed that the
initial structure was built between 100 and 500 million years ago, i.e
before the star appeared. Overall structure is coherent with the
pre-decay architecture of veil stars A and B in Finistelle.
Prospective conclusion: Przybylski's Star is a collapsed gate to the Pale Path.

The world is porous. Reality has holes and gaps running through it like the tunnels in karst. We have been aware of this ever since the discovery of the geometry drive. It cuts passages through reality then sews them back in its wake.
It is not, however, the only example of dimensional engineering in the galaxy.
The Pale Path is ancient, probably more than the Sequence, though it is hard to assess the age of such a feat of dimensional engineering. The oldest references to its existence have been found on Kapteyn which, as far as we can tell, would mean the Pale Path is at least a billion years old. Of course, the perception and effects of time can be less than intuitive when dimensional works are involved.
Interestingly enough, we heard of the Pale Path way before encountering it in the flesh. In retrospect, it was obvious that the inscriptions on Kapteyn talking about a slithering trail through the void referred to the Pale Path, but at the time we did not have any point of comparison. More explicit were the Sequence writings identifying a webway pattern circling the galaxy as a potential target for a genocidal crusade, though they led us to believe the Pale Path was just some kind of derelict wormhole network similar to what the Sequence itself seemingly tried (and failed) to build aeons ago.
The discovery of the Finistelle Veil, the first entrance to the Pale Path ever found, showed how wrong we were. Granted, on a surface level, the Pale Path can be considered like a wormhole-adjacent FTL system, connecting a network of ancient gates together through the halo of stars and dead galaxies circling the Milky Way. If it was only an FTL network, it would already be an impressive feat of generation engineering, the only means of FTL travel other than the geometry drive, surpassing even the achievements of the Sequence. However, the Pale Path's nature as a wormhole network seems almost accidental, a by-product of the real nature of this dimensional architecture.
In theory, the inside of a wormhole should be empty. That is what wormholes are, tunnels through time and space, and the inside of a tunnel is only used for transit. This is not the case for the Pale Path. The inside of its wormholes grows and expands into localized subspace phenomena we baptized Metrics. A Metric is a vast, albeit strangely finite, pocket universe contained within the Pale Path, that often has its own set of physics. It is unknown how many Metrics reside in the Pale Path, as the vast network has been only partially explored and some of the intermediary Metrics are downright hostile not only to human life but to the very existence of regular matter. Worse even, the Pale Path is in a state of advanced disrepair, with only a fraction of its extent having been spared by time, architectural failures, design flaws and the wanton destruction carried out by the Sequence. Our preliminary studies revealed that only a fraction of the Pale Path might be still intact, with 5 to 6% of its original Metrics being accessible by humans.
In very simple terms, the Pale Path is a five hundred thousand lightyears long string of parallel worlds.
