Uru Surface Routes
Cataloging the history and intentions of Cyan's portrayal of the Great Shaft in relation to Ti'ana's cave and the caldera.
This document aims to compile everything we know about Descent and surface routes from all sources. It has a particular focus on the location of the Shaft given its incongruity within the sources. This document is meant to be exhaustive. As such, please suggest additions/corrections, and skim through any part as desired.
Given the supreme canonical status of Uru/MOULa, adding Descent’s route from the Shaft’s terminal to the surface in line with Uru’s original creators’ intentions is critical, lest fan-made additions rupture the game’s canonical nature. Determining where Cyan’s creative directors most definitively intended the Shaft to be is therefore subject to investigation.
The sources that bear on deciding the Shaft’s location in relation to the caldera and Ti’ana’s cave are as follows:
Dr. Watson’s 2003 post about Zandi and other DRC communications
Uru
RAWA as Word of God
Myst 5
Book of Atrus (BoA)
Book of Ti’ana (BoT)
non-canon sources such as (ex-)Cyantists’ commentary, the Descent demo, and other files.
Tiers of canonicity are usually imposed on these sources, with the first listed overruling any below: Uru (in-game and out-of-game) and RAWA > Myst 5 > BoA/BoT >> other information
There are two surface routes to D’ni via the Shaft presented across the sources:
Caldera tunnel (featured in: BoT, BoA, Myst 5)
Ti'ana’s cave (BoT, DIRT) and Branch’s path (Dr. Watson)
The presentations between BoT/Dr. Watson vs. BoA/Myst 5 are not reconcilable. Regardless of why this happened historically and how intentional it might or might not have been, there are two distinct geographies.
Concise descriptions of the Shaft’s location from each source:
Dr. Watson: Branch’s cave is reasonably near the Shaft, taking only a “short” time to reach.
RAWA: Ti’ana’s cave is ~35 miles from the caldera.
Myst 5: The Shaft is so close to the caldera it might as well be above it.
BoT: Ti’ana’s cave, known from the sounding circle to be close to the Shaft, is ~25-35 miles from the caldera based on rough estimates of traveling time.
BoA: The Shaft is very near the caldera entrance.
DIRT: The Shaft is beneath “Ti’ana’s cave.”
CONTENTS
URU, DR. WATSON, and RAWA
Each item in this section is canon.
From URU:
Dr. Watson wandered through tunnels for days after Phil Henderson’s supposed death. He left a journal in an eder tomahn that explorers could access starting in 2004.
He wrote about this eder tomahn in the journal, saying:
This very room where Ti'ana once rested with her young son Gehn; where Gehn and his own son Atrus slept along their journey. This small room, on the cusp of the grandest of rooms. A tiny resting place half of the distance up (or down) the Great Shaft itself; a pause - half way between here and there.
The same entry concludes that “I am returning to the surface to [take Yeesha’s journey].”1
According to DRC research:
Ri'neref also made it a priority to install massive fans that would supply the cavern with fresh air. Natural openings existed but it was quickly discovered that they did not supply ample circulation for the cavern. As a result, massive shafts and fans were built and installed over a thirty-year period between 84 and 114 DE. It should be noted that numerous records point to a small group of D'ni disappearing upon completion of the fans. It is most often assumed that they remained on the surface of Earth to live.2
From Dr. Watson:
Watson: “while exploring in some caverns, Branch stumbled upon what we now know were D’ni digging machines.”3
This does not specifically say that Branch went in the same way Ti’ana did from the surface. It is also possible to argue IC Wingrove based his Ti’ana account on the actual Branch account.
Watson: “1988, March 19th to be exact, that Branch and Elias made their first trip into the caverns, as documented in Elias’ journal. It was a short one, through the entrance, through a small crack, suddenly into D’ni-made tunnels, past the long abandoned diggers, and eventually to the top of the shaft.”
This description matches Anna’s route in BoT, making that part not a Wingrovism. In BoT, there was a tunnel entrance, then a small crack that they made, around the sealing substance, and then a series of cracks and chambers before Ti’ana reached the D’ni-made tunnel, and eventually found the diggers. Watson implies the Branch route is near the Shaft, but it is obviously unclear how relative “short” is supposed to be. This description also largely matches what is seen in the Descent demo.
Watson: “It was in 1989, on their third major expedition that they reached the great D’ni cavern and saw the ruined city.”
So far, Watson has mentioned every journey made.
Watson: “[In 1989] Elias began the process of purchasing thousands of acres of land surrounding the area where the tunnels had been found.”
This came to include the caldera, land that Zandi inherited from his father.
“Tunnels” is plural, presumably referring to the entire network based around the Shaft
Watson: “...in 1990, Branch, Elias, and myself were ready for our first major expedition to D’ni together. I must admit, with every new thing I saw; with every step I took; the further I got from the surface; the closer I felt to home. That journey ended up lasting more than three weeks and brought the three of us all the way to Ae’gura. It was there we discovered a number of artifacts, including, most importantly, the journals of Catherine.”
The Watson-Elias-Branch journey in 1990 to the city took three weeks, presumably as they were having to find a novel path without any foreknowledge.
Watson: “By 1992...I formed an expeditionary group, with a few of my former colleagues, to perform a much more detailed and lengthy examination of the cavern...from that trip in 1992 until now [2003]; the city has never been completely uninhabited.”
The DRF arises.
Watson: “In 1994 I organized two massive supply trips to move large amounts of supplies and equipment to D’ni.”
Presumably further equipment would follow whatever route this is.
Watson: “1995 proved to be rather interesting. It showed the largest spike of small groups of people going out into the desert, looking for a path to D’ni. Invariably, they claimed they were “called” using that same term that we had used.”
1995 is BoA’s publication date, so this is presumably an allusion to that.
Watson: “In late 1995, November... Elias’ son Jeff was with them. Jeff had been down several times before...“
By late 1995, the proto-DRC crowd was making quite regular trips through Descent.
The Watson post of 2003 appears to deliberately replicate BoT. Dr. Watson would not be Wingrovizing; this is when explorers are rushing to the Cleft. However, several years later, DIRT elements have been appropriated for Myst 5 and its caldera choice.
From RAWA:
<Ubi_Khatie> Did Cyan originally want the cleft to be in New Mexico?
<RAWA> Short answer: Yes, as far as Cyan is concerned, the Cleft has always been in New Mexico. Long answer: Our intent was always for it to be in New Mexico, though we had no intentions of revealing its location at that time. In our outlines for the novels, the Cleft was near a non-descript volcano in a non-descript desert. Any "clues" to its location were added by David Wingrove when he fleshed out our outlines.4
Per Tweek, a ~2019 conversation with RAWA included that Ti’ana’s entrance is a “2 day walk, southwest (around 35 miles) from the Cleft.” This conversation occurred after Tweek considered adding a telescope that would allow viewing the caldera from a version of the Ti’ana entrance he was creating.
From Activity in the Cavern (2010):
Adherence to canon requires conforming to fan-made as well as Cyan-made canon. As such, the 2010 Activity in the Cavern episode as documented on the DRC forums, in chatlogs, and in the Chiso booklet are relevant.
The booklet’s passages relating to Descent:
Some trying to follow old routes to the Cavern found they were no longer passable, and even those who were following directions that had been passed to them by those already there were either getting lost or finding the route difficult to get through. Indeed it appeared that the vibrations caused by the sudden arrival of a large number of explorers had resulted in a partial collapse in long dormant passageways, and new paths had to be found.
On the surface, the Guild of Messengers was managing to pull together bits of information that were filtering back from those trying to find their way to the Cavern and posting notices to help new arrivals avoid the dead ends.
IC chatlogs material of relevance:
Feb 6: Marie Sutherland: If word gets out that you have found a way down, I'm sure others are bound to follow5
Feb 7: Dr. Kodama: I do not doubt that those who are Called will find their way down soon enough.6
This is a canonized account that followed contemporaneous discussion among beta testers about the IC nature of their work. Many MOULa beta discussion threads concern such debates, and how the testers at the time sought to learn what Cyan considered their place, and what they themselves wanted their place to be.
A major dimension of this was the status of ICers like Tweek, Giles, Whilyam, Chloe, and others who had been in the Cavern since the 2nd Restoration closed. Naturally, no one wanted to foreclose the validity of their work. At the same time, not everything could stand as canonical.
RAWA addressed this situation. He met with beta testers in Cavern on Feb 4 to discuss things before beginning the DRC forums discussion, including stating that he “had pictured IC stories from those who have found a way down before the others.”7
On Feb 5, RAWA wrote
as you can tell from the lack of specific details in Laxman's posts (and upcoming posts from other DRC members), we are intentionally making an effort to not step on the toes of those who have been telling stories from the perspective of having stayed in the Cavern all this time. I ask you all to do your best to do the same.8
As such, Activity stems from the viewpoint of needing to preserve ICers work, and provide an IC viewpoint of the beta testers and other first returnees in 2010.
As Uru canon stands outside this book:
Authorized Explorers are canon. The DRC brought them down in early 2002. Late 2002 saw Preafter, Zandi, and the provision of Relto books to all the Called, bringing them to the Cavern that way. This dynamic never changed.
Newcomers since 2010, if not the first returnees, always come to the desert and get a Relto book. The Cavern via Relto has been the method for all explorers since late 2002. Historically, explorers had to leave if the DRC left, nevermind Relto books, and that Zandi would probably always be there, not caring about the DRC’s absence.
This pattern was broken since 2010 as explorers are back but the DRC is not. It was also broken by those who remained/arrived 2008-2010.
Nonetheless, in 2010 both Kodama and Sutherland imply the Descent was used, something RAWA’s comments also suggest; RAWA is also listed in the journal’s credits as having reviewed it.
Dulebohn’s AGM appearance has stated that Restoration work is needed to bring Descent to us.9 Further, some testers/Maintainers are already thinking about doing things, e.g. writing IC journals, that will view Descent’s arrival as a novel IC development.
Regarding the DRC surface route:
Presumably it was the “DRC” that added the ladder as seen in the Descent demo. This logic would presumably also hold for what was seen in Myst 5, the inside of the caldera. Watson would likely have been in the caldera before. Although, Esher seems to believe he never was, as he gave advice. In fact, Watson is being spoken to by Esher throughout Descent as if Watson is ignorant. Even Esher should be able to know Watson would know these things. All of this could be understood as dramatic embellishment for the sake of the game's player.
MYST 5
Canonically, Myst 5 is a video game Cyan made that URU NPCs have substantively corroborated.
Yeesha identifies the caldera as being where she, Atrus, and Ti’ana all began their journeys. In her journal, Yeesha further described Ti’ana as beginning her journey in the caldera, writing: “From the place where Ti'ana first climbed downward” when discussing her own intentions to descend to D’ni.10
There is a DRC-stamped illustration found in upper Descent. The text is hard/impossible to read.
Cyan reused the DIRT demo. They could not use its surface elements, since those would be identifiable as Gira. They replaced this with the inside of the caldera. Cyan’s thinking about what this meant for the canon nature of the place is unknown, including whether they would have opted for something else if they had the time and manpower.
The 2004 decision to place the Shaft at the Myst 5 caldera follows the precedent of BoA, and not of BoT’s indication.
Myst 5 contradicts RAWA’s authoritative comments about Ti’ana’s cave being 35 miles away.
The text in the starting tunnel in Myst 5 has the numerals 20 and 15 (515), with characters above both. Descent demo has none. Aitrus’ map shows the caldera with the same numbers. The D’ni text is presumably some kind of abbreviation.
BOOK OF TI’ANA
Aitrus’ map puts the Shaft below the caldera.
Ti’ana and Gehn emerge from the caldera at the end of the novel and walk to the nearby Cleft.11
There are mountains “far to the east” of the caldera.12
Anna and her father discovered the circle “on the way back from a survey of a sector of the desert southwest of the dormant volcano.”13 The circle is very near Ti’ana’s cave.14 The way to Tadjinar would not take Anna past the circle.15
“They were traders, out of Tadjinar, heading south for the markets of Jemaranir.” is said about the traders who are at the circle when it is formed. Tadjinar is to the north of the circle, and thus to the north of the caldera.
The Lodge was lodged into a shelf between a rock wall and the shelf below. A narrow stone bridge linked it to the rest of a rocky outcrop over a broad chasm, nearly sixty feet deep.16 The Lodge is several miles from the tunnels and the machines.17
Anna’s father commented that if she left the Lodge at sundown, she would reach the volcano before dawn, and could seek shelter in the cleft there. This is identified as being commonly done, which would make sense, as it is their journey between the Lodge and Tadjinar.18
It is a mathematical fact that the Lodge must be to the southwest of the Volcano, the same as Ti’ana’s cave.
If Tadjinar is to the north or northeast, BoT geography is sound. The Lodge is then either between the caldera and Ti’ana’s cave, or nearly so.
Contrary to a repeated misconception, the geography of BoT is not an absurdity, but is reconcilable with itself.
Further details in BoT:
They went through the gap between two of the converging ridges, then climbed up over a shoulder of rock onto a kind of plateau, a smooth gray slab that tilted downward into the sand, like a fallen that has been half buried in a sandstorm. Across from them another, larger ridge rose up out of the sand, its eroded contours picked out clearly by the sun. The whiteness of the rock and the blackness of its shadowed irregularities gave it the look of carved ivory. “There,” he said, pointing to one of the larger patches of darkness near the foot of the ridge.
Anna’s father identified the darkness as a tunnel. The two crossed over sand and ducked inside the shadowed entrance to the tunnel:
The tunnel ran smoothly into the rock for fifteen, twenty paces, but that was it. Beyond that it was blocked by rock fall.
The walls looked lavatic. The rock that blocked the path was smooth and glassy, just like the walls. Anna’s father identified signs of an earthquake that had occurred some miles to the north of there, and probably recently. Said there had been a major quake thirty years back, which could also explain the circle.19
After making a gap, Anna went over the rockfall, with a slight downward drop. A hundred paces onward, there was another rockfall. To the left of this fall, there was a crack in the tunnel’s wall large enough for a person. This crack was deep, with the floors falling steeply, and with a breeze coming from it and water audible from inside. This crack ran for twenty paces, and then leveled out its slope. Then, it turned sharply and came into a cavern. Here was a stronger sound of water, and a tiny stream. Approximately 20 yards above, there was the red stone. This cavern turned into a funnel at its near end, away from the crack. The entire end of the narrowed cavern was filled with a sheet of the D’ni’s red sealant stone.20
The second time she explored this place, Anna fell 4-5 feet while getting past the block. She also found a gap behind the mass of mysterious red material. Inside, there was a cave with a floor composed of the red material and a ceiling composed of the black rock like in the first tunnel. The ceiling in this new cave formed a bell, as if the cave was a pocket. At the far end, the ceiling dipped, and there was another gap. That gap went back ten yards, and ended in a wall of the red material. To the left in that tunnel, there was another crack, curving around the red mass to its right. Then, a sharp left turn away. Then, the crack opened up. There, finally, was a flat floor and regular walls.21
This cavern was huge, with the first part Anna entered being only an antechamber. This chamber contained the two massive, insect-like digging machines. Low in the wall of the great chamber, there were two circle tunnels, sloping down, with the same green-black stone lining the walls as also lined the great chamber. There was a storeroom next to these two tunnels.22
The green-black stone could not be chiseled. This material is presumably nara.
After going into one of the two tunnels, Anna became lost in a labyrinth.23 She was eventually either found by D'ni or found her own way down to the Cavern. There is no mention of the Shaft from Anna’s perspective.
Aitrus, Anna, and Gehn’s trip up Descent took two days to reach the digging machines. Aitrus identified the red material as a sealant.24
On this trip, Aitrus used explosives on the rock fall.25
Within Aitrus’ notebook were:
…a series of maps and diagrams Aitrus had made. The first were of the tunnels leading to the cavern where the machines were and, beyond it, several miles distant, the Lodge. Aitrus had added to this map, drawing thick dark lines across a number of the tunnels. It was clear that they were blocked. Indeed, looking at the map, [Anna] saw that there was no access to the surface by this route.26
The next map was different - much more complex...It extended over several pages...elevations, rock-types, physical details-all were noted down. It was a real labyrinth...it came out at the old dormant volcano.27
There is a connection between the tunnels beneath the caldera and those Ti’ana first found. The Shaft is absent from these descriptions.
The Shaft’s construction had preparations that involved excavating a massive chamber beneath the shaft.28 This chamber was supported by twenty granite pillars. Slabs of nara were used on the walls, riveted into place. A rivet was bigger than a person, and more than 8000 were used. This massive chamber also featured a large camp in the western end to coordinate logistics. Support tunnels back to D’ni were excavated to improve the massive influx of persons and material.29 This chamber later included a large floor mosaic of the D’ni city among other decorations at the sight where the shaft stretched upwards.30
As well,
…the great shaft was to be the hub of a network of much smaller tunnels that would branch out from it. Most of these were service tunnels, leading back to D’ni, but some extended the original excavation to the north.31
Half-tracked wagons were used to transport the digging machines to the large chamber at the base of the Shaft.32
A platform was to be made two-thirds of the way up the shaft so as to use two of the digging machines.33
The plan included putting nara on the shaft’s walls and adding cross-struts. The spiraling path was added alongside polishing the walls as later steps in the process.34
The Shaft was made next to a large cave, but it was “some way off” and the shaft was not beneath it.35 This cave system in some way relates to the caves of Ti’ana.
There were eighty ventilation fans, each blade ~3 meters long. These were turned on once the shaft was completed.36 The digging machines were rapidly dismantled and shipped back to D’ni.37
The plan was to have a final tunnel that would be dug after the top of the shaft.38
An earthquake damaged the Shaft during BoT. The platform was threatened, and there was a crack up the side of the Shaft, rupturing the nara sheet. The rock covering the final, horizontal tunnel was visible from inside the Shaft. This tunnel was partly blocked, and a cutter was deep inside, trapped. The quake ripped away some of spiral steps’ outer walls.39 Repairs were ordered, but no final breakthrough was ever completed, held off indefinitely.40
The surface circle was created by a “sounding,” as D’ni instruments surveyed the rock above.41 The powerful sounding that made the circle was described as finding clear rock all the way to the surface.42 Surface-dwellers noticed it as a massive circle.43 Per Anna’s investigation, it has an 80 pace diameter, for about 800 square feet.44
BOOK OF ATRUS
The route that Atrus and Gehn use to reach the Cavern is derived, possibly without any deviation, from Aitrus’ notes. This route is plausibly still intact, but nothing establishes that it must be.
After an experiment of his explodes, Atrus notices a cave or tunnel within the caldera. “Almost as though it had been carved from the surrounding rock”.45 This cave was such that it could be “stepped inside”, once Atrus explored it that night.46
A huge D’ni word was cut into the wall, over fifty paces in.47
The account of Gehn’s and Atrus’ descent begins in the immediate tunnel from the caldera. Gehn identifies it as a lava tube. It does not take long for this tube to meet the Shaft.48
BoA identifies the Shaft as near the caldera, putting the digging machines and Ti’ana’s cave very far from the Shaft.
Wingrove re: BoA: “But the idea was Rand and Robyn’s. They knew where it started. Knew what elements should be there, down by the volcano.”49
DIRT DEMO, DEV HISTORY, AND COMMENTARY
The “Surface area outside TianaCave” document states that:
for the upper portions of the trip to D'ni, this area was to be part of a very large desert. In the name of expediency toward completing this area for the demo, we've truncated it a bit. In the future, we may decide to allow Simon to go the the Cleft.
Cyan’s plan involved possibly having both the Cleft and Ti'ana’s Cave. It also intended for the player to find the Shaft below Ti'ana's cave, not at the caldera.
Mysterium 2001 unveiled a video showcasing the old Descent, including the later repurposed Gira. This is after there was an early 2001 caldera modeled, per photos released by, presumably, Josh Staub. These were probably thought of as a further location to eventually be made, unless Cyan showed the Mudpie film with a concept already abandoned.
Chogon has commented on DIRT content in the OU discord, implying DIRT content was irrelevant for Mudpie. At the same time, there was talk of a communal area in Descent at some point, so the concept of Descent combined with multiplayer was at least entertained for some period of time.
Cyan’s website’s entry on Aitrus’ map:
Though the D'ni did not know it, when the shaft was finished it was extremely close to a series of caves that existed underneath the nearby volcano. The caves provided a route -- a dangerous route -- that would enable a surface dweller to reach the "sealed" shaft.50
Tweek: “As far as I can tell the Great Tree structure that we see tied on to the Great Tree pub in Uru was going to be part of the path down to D'ni at one point. I seem to recall it had a Linking Book in it I want to say to Teledahn but I can't remember for sure.”51
Many files from the demos seem to be about the Great Tree area.
SITUATION AND PLAUSIBLE SOLUTIONS
Canon via word of RAWA: Ti’ana’s cave is ~35 miles from the caldera.
Canon via Uru: some explorers never left the Cavern after the Second Restoration ended, staying behind with their Relto books. A corollary may as well be that those who came into single-player Uru between 2008-10 should be left space for their IC Calling in this period.
Canon via Dr. Watson: a full route of some description was available as early as 1989.
Canon via Dr. Watson: The Shaft is a “short” distance from Branch’s cave, which leads quickly to D’ni digging machines. The “short” trip might be relative to going the full (and at the time weeks-long) journey to the Cavern.
List of suggested criteria:
To not contradict anything that is already canon.
To reconcile as much as possible from all of Cyan’s products.
To not restrict anymore than absolutely necessary the space for explorers to IC.
Proposal 1: Caldera with Shaft
This would have a Shaft very near the caldera, following BoA’s presentation and the map of Descent.
BoA was written in 1995. BoT and its route presentation being more Wingrovized than BoA could make more sense as 1995 saw a rush of readers to the desert looking for D’ni.
It might be that BoT is a fictionalized account not so much of Anna’s journey, as it is of Branch’s journey.
Squinting at Dr. Watson’s comments, despite being the highest tier of canon, can be done so that the relative language he uses puts Branch, and by extension, Ti’ana far away from the Shaft.
As it stands, Doobes’ Descent (coming from Myst 5) starts at the caldera. Uru’s Descent is, especially if Calum’s lava tube is used, heading in a distinctly BoA-style direction. Elsewhere in the community, work has been done on T’iana’s cave, preserving it as a separate locale.
Proposal 2: Ti’ana’s cave with Shaft
A Shaft under the caldera was presented in Myst 5 (2005), something with BoA precedence (1995). The DIRT demo suggests something like BoT suggests, and not like BoA. 2001-02 plans for the Cleft as an additional place in the game separate from Ti’ana’s cave maintained this approach. Watson’s 2003 post does not deviate either, it being reasonable to infer he is suggesting the Shaft is near Branch’s cave. Myst 5 put the Shaft under the caldera, possibly only because Cyan had been first pressed to make ABM and reuse the Gira surface, and then pressed again to produce Myst 5 structured around Descent without its desert start. As such, this proposal argues that the Shaft being near Ti’ana’s cave is more authentic.
It would also argue that it is unreasonable to maintain that Ti’ana wandered for an absurd amount of miles and that the digging machines could be located so far from the Shaft. Further, as the DRC controls only the Branch entrance and not the caldera, being extremely distant from the Shaft might be too odd - or explain one aspect of the DRC’s hostility to Zandi.
Chronologically, this is the presentation of the Shaft’s location:
The earliest presentation of the Shaft is in the Book of Atrus, published in 1995, where it is beneath the caldera.
The Shaft is nearly explicitly presented as being ~35 miles to the southwest of the caldera in the Book of Ti’ana (1996.)
When Cyan was developing DIRT in 2000, the Shaft was presented as below Ti’ana’s cave. The caldera and cleft were being modeled at the latest in early 2001 for MUDPIE52 - for unknown intentions.
Uru does not contain the interior of the caldera or the top of the Shaft. The DRC’s access route is not stated, but cannot be the caldera as it is Zandi’s. Dr. Watson describes Branch reaching the Shaft from a very similar approach as Ti’ana.
When developing Myst 5, the Shaft is placed below the caldera.
At its crudest, this history suggests Cyan meant for the Shaft to be at the caldera, then near Ti’ana’s cave, then at the caldera again. The easiest explanation for the caldera location could be that first it was a Wingrovism, and then when revived in 2005 it was a gameplay decision since Cyan could not use “Gira” anymore and modeling the interior of the caldera was simplest.
