Oblivion got remastered and we could all return to Tamriel again

(as if we didn't already live rent-free in that world). Weeks before the game was released there was a multitude of leaks from supposedly legit sources. The leaks never panned out until, at the last moment, they did. All these leaks created three camps: those who adamantly defended the veracity of the leaks, those who were cautiously optimistic but skeptical, and those who fervently denied it being true. The last one was based on something Todd Howard had said in an interview back in 2016 when Skyrim Special Edition released: that remastering Oblivion and Morrowind would be too much work, they were too old and too different. But since then there has been a Microsoft acquisition, and now we can surmise that it's Microsoft that's pushing for these remasters. 

Throughout the weeks of leaks I watched the moderators on the Bethesda Game Studios discord server work their asses off in removing all mentions of leaks as they allowed nothing unofficial on the official BGS server. Makes sense. And then April 21st happened:

Once that image dropped the Oblivion discord server EXPLODED. We went from 2000 members to 7500 members in a WEEK. The subreddit emerged as one of the most active gaming subreddits on the entire site. Not bad for a game that's technically 19 years old. We all watched the reveal video as a community on April 22nd and freaked out together on discord.

I was still playing Pillars of Eternity 2 at the time of the drop and wanted to finish that. I started to play the Oblivion Remaster four days later, on April 26th. I finished last night. The intro made me cry and after that first time I'd still feel teary-eyed the next few following times I booted up the game and got the menu. It's so good T_T

They spruced up the character creation a bit, now each race has two different origins. As usual I created a Dunmer, but this time a Dunmer specifically from Vvardenfell. Amazing. I didn't like any of the hair styles though, and ended up covering it up with a hood for most of the game. My favourite playstyle in Oblivion is a Monk build. It's very satisfying to play as a female elf running around in a dress and punching things to death. 

The Feather enchantments and spells became my new best friends as I set out to explore the world. I used Map Genie as I went to make sure I didn't miss anything. By the time I finished I had explored every single location, closed all 60 Oblivion Gates, completed every single questline, and run out of quests to do. 

The Ayleid ruins are mesmerizingly beautiful. The first time I played the original Oblivion I thought they were extremely creepy, but now I was just wandering through them thinking how goddamn beautiful they are. 

The entire world was beautiful tbh, and I wish they had added a feature to hide the HUD for better screenshots. 

The Shivering Isles was amazing. I loved the extreme dresses xD And I really liked how they made Sheogorath look. Haskill looks so sweet and kind. Although, once again Taxonomy of Obsession made me want to close the game down and never return. Eventually I did complete it though.

Overall the game felt very similar to playing Skyrim in 2012 in that it would unexplainably CTD every so often. I've seen a lot of people with high-end rigs being unable to play it at all. I had very minor issues though. Every time I loaded a new zone after a loading screen I'd get a bit of stuttering and textures being slow to load in, but all I had to do was give it a moment to properly load and it would run smoothly after that. The remaster also didn't fix any of the known bugs and glitches from OG Oblivion. They're all still in the game lol.

My first major bug happened at the end of the Mages Guild questline where Mannimarco just wouldn't aggro. In OG Oblivion I would have simply used console commands to fix it, but in the remaster using the console disables achievements. I was 60 hours in at that point. So I turned to Nexus. Modding the game would also disable achievements, but I simply installed the Mages Guild fix mod as well as one achievement enabler mod and I was good to go. Finally Mannimarco aggro'd properly. As an added benefit I could now use console commands without disabling achievements. 

My second bug wasn't really game breaking, but it was annoying nonetheless. At the end of the Knights of the Nine questline they give a speech celebrating your victory. The speech got interrupted by a bear getting too close aggro'ing all the knights and after that the knights would just be stuck outside the Priory, unable to be interacted with. I didn't realize they were stuck until I returned there many hours later and at that point I had no past save to reload to make the speech run properly. 

Another bug that seems very prominent which also happened to me was during the main quest when you would go to Sancre Tor to pick up Tiber Septim's armor. You're supposed to free the ghosts of four ancient Blades by defeating their skeletons. But when I got to the fourth one, the ghost had already spawned and the skeleton was actively attacking it. I defeated the skeleton and the ghost would just stand around where he was instead of walking to the crypt with the others to unlock it for me. I fixed it by leaving the zone and waiting an hour. When I returned the ghost was moving to where he was supposed to be. 

I'm very proud of myself for completing No Stone Unturned and Work Is Never Done without the use of console commands. I wanted to play the remaster as vanilla as possible and it annoyed me so much initially that I had to resort to mods to get the Mages Guild questline to work. 

The Deluxe Edition came with two new quests. The Burning Trail quest was a little treasure hunt leading up to a meeting with the Mythic Dawn, which eventually gets you the Armor of Cataclysm and the ability to summon Mehrunes' Harbinger. The A Wound in Time and Saving Time Itself quests did make me raise my eyebrows a bit on the lore front. These quests, being in a mainline game, make it so that not only has an Elder Scroll been stolen before, but also that Elder Scrolls are verifiable means of time travel, the Order of the Hour are keepers of the Scrolls, and mind degradation is inevitable for any and all liches. It's uuuuuh... It changes a lot of things. The Armor of Order you get from those quests did look badass though!

I was really looking forward to seeing the final showdown between Mehrunes Dagon and the avatar of Akatosh in upscaled graphics and omg it delivered *w* 

The only issue was that after the fight Ocato comes up to talk to you and after that the final cutscene starts and once the game returned my character would be stuck in place. I couldn't move, couldn't even bring up the menu and the last autosave I had was when I entered the Temple of the One just before Martin goes dragon. I ended up having to watch the final fight showdown six times while I tried different fixes I found online before I finally managed to get my game to work again past cutscene. The way I did that was by running away from Ocato before he could talk to me, I ran a circle around the dragon statue back to the door and exited the Temple of the One. The game got stuck on a black screen attempting to load up both the final cutscene and the outside of the Temple. I force quit the game again thinking it had failed, but when I started the game up after that I had a brand new autosave from outside the Temple. Success!! Time to finish the Shivering Isles. 

I've actually only completed the Shivering Isles DLC once before, on my very first playthrough way back in 2013 when I played it for the first time. In every subsequent playthrough I've dropped it before completing the main questline of the DLC either because the enemies have turned too bulletspongy to be any fun at that point (the remaster fixed that thankfully) or Taxonomy of Obsession completely killed my vibe. I had forgotten most of what happens after you take one of the Duke spots. It was cool to see Jyggalag :3

Most of my screenshots from this game are landscape shots, and I'll finish this post with some of those.

This game was the best unexpected surprise release in years. Now, do it again, but for TES 6.

More Pillars of Eternity yap

As much as I'm deep inside the Oblivion Remaster right now, I still can't stop thinking about Eora. Since my last post I've replayed both Pillars of Eternity games, in fact I was approaching the end of Pillars of Eternity 2 when the Oblivion Remaster released. 

Having come to certain realizations during my first playthrough, my second playthrough leaned heavily towards animancy, which didn't endear me to a lot of people.

Second time around I also played around more with the console and also downloaded a couple mods for PoE 2. Specifically to make Aloth's romance spicier and more prominent. I love that elf ♥ But it did make for some hilarious moments. Not once did I remove Aloth from my party in either game, this time around. 

Maybe not the best time, Aloth?!?!?! xD

I enjoyed the Beast of Winter and Forgotten Sanctum DLCs a lot more the second time around. Llengrath is still salty as hell after her defeat in PoE 1. And there's no universe where I won't pick the Aloth option when she asks me what I plan on doing next :3

Rymrgand, Wael and Berath may be my favourite gods. Wael is just a lot of fun. Rymrgand has such a melancholic attitude which I can't help but find refreshing and slightly funny, like a teenager who tries to maintain a k /care attitude whenever the Watcher does something that upends his own doings. Woedica is a bitch, will always be a bitch, and I will take every opportunity to rile her up. 

I loved Edér the first time I played, but this second time around he exasperated me more than I found him endearing. Kana grew on me to the point I really wished I could just switch Maia with her brother, because Maia is no fun. But at least Pallegina survived this time around. Tekehu is pretty fun, but the more I have him in my party the more I realize how very young he is. And so idealistic. I understand why Aloth is constantly exasperated by him. Xoti is very sweet, though, and she has grown on me. 

I used Rekke, Vatnir, Ydwin and Fassina a lot more this time around. I really like Rekke and I hope we'll get to go to Yezuha in a future game. It's been hinted at in both PoE 2 and Avowed at this point! Even the last ending slide in PoE 2 talks about what lies beyond the ocean to the east.

It's very possible that I'll play these games again. Before the year is over even. I need a Pillars of Eternity 3 at this point, but I'm willing to settle for a DLC for Avowed, pretty please?

Resident Alien S02

The second season finally dropped on Netflix and we were pretty quick to start watching it. This second season is a lot more serious than the first one, but there's still a lot of comedy in there. 

This season explores Harry's burgeoning humanity and we find out who it really is that wants to destroy the Earth.

I wasn't sure about the entire alien baby plot line but it worked out in the end. Finding out who Goliath really is wasn't as big of a plot twist as it should have been since I figured it out way before they dropped that figurative bomb. But eeeh, it was good enough. 

I enjoyed this season a lot.

Game completed: Split Fiction

After we dropped Raft we decided that we wanted something we'd be sure to enjoy. Hazelight hasn't steered us wrong yet and Split Fiction had just released so we started on that.

To start off the game is absolutely stunning. So many sequences looked like movies and I was often sat there like "I can't believe I'm playing this".

As always Hazelight plays around a lot with mechanics, gameplay and genres. It isn't unusual for a single level to have action adventure, but also, third person shooter, but also metroidvania, but also bullethell, but also side-scrolling platformer, at one point we had a top down shooter, and iirc there was also a sequence of tower defense and isometric gameplay. But most of all it's a puzzle adventure. 

We both commented on the game being seemingly a lot more linear than It Takes Two, which had a lot more side content and things to interact with and play around with on each level. Split Fiction is mainly about getting from point A to point B, but it does it very beautifully. 

The side stories were always a great surprise and could be anything at all, ranging from children's stories about flying pigs to sci-fi stories about exploding stars. We had the most fun with the pigs one and the teeth and candy one. 

Originally the game goes through one level fantasy, followed by one level sci-fi, followed by one level fantasy etc etc, but as the overarching story progresses the device begins breaking apart and the last level is a mess of jumbled fantasy and sci-fi elements and it's so goddamn cool!

Black Mirror S07

This season of Black Mirror was sad. Not that it was bad, just that every single made us feel sad in some way.

Common People is about a couple where the wife has an aneurysm and is left brain dead, but new tech can compensate for the area of the brain that doesn't work anymore, provided they pay for a subscription. The husband being heartbroken agrees with it, and as time goes on the subscription gets progressively more expensive as they're forced into higher tiers to be able to maintain quality of life without forced ads. This episode left us sad for the rest of the evening.

Bête Noire was weird about tech that can alter reality and people's perception by playing on the multiverse. Quantum theory science fiction stuff. We didn't much like this one.

Hotel Reverie is about remaking old movies with AI, where they send an actor into a movie via consciousness transferral. But if the actor doesn't stick to the script weird things happen and they may get stuck in the movie unable to go home. The actor can't go home until the movie is complete. It was pretty cool, but also very sad in the end. Emma Corrin is a star.

Plaything is very weird, but Capaldi is amazing. This episode is about a game literally taking over a guy's life and using that guy to literally take over the world. 

Eulogy was very sad. Not as sad as the first episode, but it's a story about reminiscing. Delving into memories quite literally via tech and old photographs. By going into the background of those old photographs the guy discovers that multiple misunderstandings, miscommunication and missed opportunities led to him eventually spending his life alone. 

USS Callister: Into Infinity was a sequel to season four's USS Callister and this was probably the most brilliant episode of the season. I had a great time with this and it really felt like a high-budget sci-fi movie. Still loving the Star Trek.

Speculation on Space Travel - a TES lore writeup

One common thing to do once you've studied enough of the lore is that you start wanting to put things together, like pieces of a puzzle. Collating sources and disaprate mentions of something will sometimes net you a whole new narrative. So far I've done it once and I'm working on another. This one I originally published on r/teslore back in January.

---------------------------------------------------------------------------------

I want to preface this by saying I'm still quite new in the lore space, but in the previous year I read extensively. This text was born out of a simple musing.

"The Nereid in the southwest fountain fell in love with a Dremora and followed him here through a river of memories that flows from Nirn to realms beyond. When she arrived, she found herself trapped. Now, the Dremora will not let her go." 
- Vistha-Li, Fargrave

This is the quote that got me wondering whether it would be possible to travel between realms via water. The Imperial Mananauts and the Sunbirds of Alinor were all so preoccupied by going to Aetherius via the stars, but what if it is possible to reach the stars via the oceans? Effectively going up by going down.

First we need to confirm what oceans are in The Elder Scrolls universe. Before the War of Manifest Metaphors, Nirn did not have oceans. They are said to have appeared after the war according to the Anuad:

This war reshaped the face of Nirn, sinking much of the land beneath new oceans, and leaving the lands as we know them.
- The Annotated Anuad

Add to that what we know water itself to be within The Elder Scrolls universe;

“When a mortal dies, where do you think their memories go? I'll tell you—they go into the water. They become water. All the memories of Tamriel's history are stored in its waters.
- Herald Kixathi

and the origin of the oceans suddenly portray the viciousness of the war. Enough of the Ehlnofey died to create oceans. Another water related phenomenon that is said to have occurred first after Convention is rain.

Kynareth is a member of the Nine Divines, the strongest of the Sky spirits. [...] She is also associated with rain, a phenomenon said not to occur before the removal of Lorkhan's divine spark.
- Varieties of Faith in the Empire

 Khenarthi. Elder Spirit of the Heavens [...] For some tribes she also serves as a spirit of mourning, as it is written that when Lorkhaj died she hid herself in a storm and wept until Alkosh came to comfort her.
- The Sky Spirits

“Hear me, goddess of storms, and the bringer of rain
- Kyne’s Challenge

So this brings us to the conclusion that the water and oceans on Nirn are a mixture of memories and the tears of an et’Ada. This connects us to the latest lore from The Elder Scrolls Online (Update 44):

Everything is connected. People, objects, the sea.
- Hyacinth

“Ever since I was very young, I could sense connections between me and other people. Between people and objects. [...] Through my deep magic I can sense the connection between people and objects. [...] I reached out through the connection we share and manifested a moment that happened [...] I pulled on our connection to see memories of her past, right? What if I try to push on that connection and use it to open a portal straight to her?”
- Tanlorin

These tidbits of dialogue points to emotions and memories connecting people’s souls not just metaphorically, but literally, and that that connection can be used to open portals by people well-versed enough in that kind of magic. So the possibility of using water to travel is already implied on the basis that water is memory and memories are a connection.

So let’s explore means.

My thoughts first went to the Dwemer. The people known for their science and technology, who mysteriously vanished, and who seemingly used to travel to other realms if Yagrum Bagarn is to be trusted.

“I cannot say what happened. I was not there to observe. I was in an Outer Realm at the time, and when I came back, my people were gone.” 
- Yagrum Bagarn

Following the Dwemer line of thought I found Aetherbells, vessels that could “dive” through the realms of Aetherius and Oblivion, if rumour is to be believed. There is no evidence these ever existed, but assuming they did, their name does not invoke the image of a “spaceship” to me, rather it makes me think of diving bells, described by wikipedia as “a rigid chamber used to transport divers from the surface to depth and back in open water, usually for the purpose of performing underwater work.”

“Aetherbells? You mean Dwarven vessels that "dive" through the realms of Aetherius and Oblivion? Honestly, Amalien, do you have even a shred of evidence to support the idea that those even exist? These are clearly constellation markers.”
- Reginus Buca, Dwemer Star Chart antiquity codex

But wait, that source mentions stars and constellations in the same breath as Aetherbells, so clearly the celestial phenomena are important? Keeping to the Dwemer line, this brought me to the Oculary at Mzulft, and what Paratus Decimius had to say about it seemed to line up:

“From all our research, it seems they were intent on discerning the nature of the divine. This machinery, all of it, was designed to collect starlight, and then... I'm not sure.”
- Paratus Decimius

With the diving vessels and observation of the sky in hand my thoughts turned to Karstangz-Bcharn, or Weather Witches, Dwarven machines capable of controlling the weather. One such machine exists at Graven Deep.

“The logbook describes this island as a Dwarven machine. They wanted to control the weather. [...] This logbook suggests the Dwarves experimented with weather control here. Weather like huge storms.”
- Dhulef

This source suggests that the weather witch was for the purpose of creating storms, but what if it instead was used to create clear skies and thus a means to view celestial phenomena clearly, implying a connection between starlight and water that we will explore later. For now, we will stick with water. Assuming the weather witch was indeed to create storms, then those storms may have had the capability of creating whirlpools. 

The whirlpool in the Abecean called the Maelstrom of Bal can make ships disappear, and may be a portal into Oblivion, but the trauma of riding its waters would surely slay any who tried.
- The Doors of Oblivion

Likewise the Pillar of Thras is speculated to be a portal into Oblivion:

We did not consider it worth the risk to leap from the Pillar of Thras, a thousand foot tall spiral of coral, though we witnessed the sacrifices the Sload made there. Some victims were killed by the fall, but some, indeed, seemed to vanish before being dashed on the rocks.
- The Doors of Oblivion

Let’s also take a look at a specific trade going on from the Systres Archipelago:

The Systres Archipelago exports many raw materials and trade goods, but none more intriguing than the eltheric ammonites. [...]  For reasons we still do not understand, these ammonites contain stores of raw magicka. [...] They also suffer arcane decay—losing potency within a month of harvest.
- Mysteries of the Eltheric Ammonite

Ammonites are a kind of fossilised shell, like the kind frequently seen in the realm of Apocrypha, whose master is Hermaeus Mora, most commonly known as the Daedric Prince of forbidden knowledge, but also of hidden shoals, whirlpools, and sudden squalls. Sailors refer to him as the Tide King and One-Whose-Tentacles-Rise-From-the-Deep, a being who lurks in the abyss and pulls ships into the depths. Those ships end up in Fathom’s Drift within Apocrypha. While ammonites in real life are an extinct group of marine animals, in The Elder Scrolls universe they seem strongly related to Apocrypha, combined with the fact that they lose their magickal potency within a month after harvest, after being removed from the proximity to the ocean, and presumably their connection to Oblivion, it can be surmised that these little fossils are tiny parts of Oblivion. 

So what do all these things have in common? The Abecean Sea is connected to the Eltheric Ocean and all of these; Graven Deep, the Maelstrom of Bal, the Pillar of Thras, the Systres Archipelago, are situated in the same general area. Graven Deep is pretty far away from any known Dwemer settlement, but the Dwemer were not a people to do things without logic or reason. The location for Graven Deep was probably chosen with a specific purpose in mind. What other significant event happened in the Eltheric Ocean? The sinking of Yokuda. Could it be possible that the people who did not manage to escape the continent sinking were not actually killed but rather pulled into a different realm?

It is debated to this day what the nature of the disaster was that destroyed Yokuda. Tremors of the earth were not uncommon in the continent's history, and many argue that it was simply a natural catastrophic series of quakes at the foundation of the land.
- Pocket Guide to the Empire, 3rd Edition: Other Lands

Similarly, Thras is of interest here. Thras was allegedly sunk into the ocean by the All Flags Navy and its Coral Tower created a whirlpool which pulled The Lost Fleet into it. An imitation of the Coral Tower using coral from Thras, as well as The Lost Fleet, can now be found in Coldharbour.

After the Sload released the Thrassian Plague in 1E2200, which claimed more than half of the continent's population, the largest allied naval force in Tamrielic history sailed to Thras, slaughtered all the Sload they could find, and, with great unknown magicks, sunk their coral kingdoms into the sea.
- Pocket Guide to the Empire, 1st Edition: The Wild Region

The blue light atop the coral tower began to pulse and bleed energy into the clouded sky. When the ground beneath our feet began to quake and tremble, no one had to tell us to run. The island began to crack and sink. The sea around Thras boiled as we rowed for our lives back to the Golden Era. We were hauled back on deck in time to watch the Coral Tower collapse into the sea. We noticed too late the current that pulled us towards it. As the eye of blue light atop the tower dipped into the sea it began to spin like a great wheel, and when it met the waves it formed a monstrous whirlpool. Half the fleet was drawn into it, our ship included.
- Journal of Tsona-Ei

Thras has been raised again by the surviving Sload, presumably by negotiating with the Daedric Princes, which the Sload are known to deal with. Thras even seems to fluctuate in size, either due to the tides or through less natural means.

The first maps we have from cartographers who sailed to Thras and returned to tell the tale show a group of sixteen islands, in a semicircle like a partially submerged coral atoll. Over the centuries other maps have been charted by spies, and the number and size of islands has varied, suggesting that the amphibious Sload have a volatile kingdom which fluctuates its land mass, either by the tides or some other, less natural means.
- Pocket Guide to the Empire, 3rd Edition: Other Lands

While this all seems to point to the fact that the ocean, and especially whirlpools, can function as a gateway to Oblivion, it says nothing about Aetherius. It is a sad state of affairs that Aetherial realms are rarely mentioned in sources aside from texts talking about afterlives. But we have the connection with the tears of KYNRT making up part of the cycle of water on Nirn. There is also a small but significant connection to the Magna-Ge, specifically the Nine Coruscations:

Sheza-Rana: The Cyan Star. The … of Water. [...] Energy that uplifts. [...] until Azura opens the Third Eye [...] Mystery, Memory, and the Unknown.
- The Nine Coruscations

Though they came from diverse waters, each Get shared sole purpose
- Mythic Dawn Commentaries 4

For further connections to the Magna-Ge it’s also possible to look at descriptions of Meridia across several sources.

as we speak to Merid-Nunda regarding the light, for she is the scintilla that fears not darkness, and swims the waves of pull and spin ….
- The Exegesis of Merid-Nunda

Vivec was borne by ribbons of water, which wrote their starward couplings in red.
- 36 Lessons of Vivec, Sermon 37

Merid-Nunda: The Red Star. Harbinger of Dawn. [...] Mirror of the Lie
- The Nine Coruscations

Merid-Nunda rose, wiping golden blood from her lips. She glanced around and saw that Dagon and Molagh were both gone, but there was no sign as to where. Behind her sang the Varliance Gate, a doorway that led to so many possible futures for her.
- The Bladesongs of Boethra

Khajiit legends make Meridia’s interest in the Varliance Gate very clear, at the same time she is loosely related to water through vernacular and the rainbow. This brings us to the connection with starlight that I mentioned earlier. The Dwemer were clearly up to something relating to the stars what with their oculory and orrery, but as far as starlight, varliance, is concerned another ancient race comes to mind: the Ayleids. 

In the lore the Ayleids have no precedent of travelling to the stars as far as I could find, but there are plenty of references to their reverence of varliance and their use of meteoric glass and iron. One of their most mysterious inventions is the Ayleid Wells, which fits well with the aquatic theme.

Ayleids Wells are scattered across Cyrodiil's landscape. Their siting is a mystery; they are not associated with any known Ayleid cities or settlements. It is presumed that, in some manner, they harvest magical power from starlight.
- Magic From the Sky

“But why … wells? The meteoric iron lining the heart of these installations is exceedingly rare. Of all the shapes they could have forged, why this one? [...] Most researchers believe meteoric iron wells emit mystic power back to the sky. Purely for religious purposes? Or is that energy … I don't know … going somewhere?
- Azandar al-Cybiades

Further the Wells are theorised to be placed along ancient lines of magical power. While these theories have not been substantiated in lore, a parallel can be drawn to the Mundus Stones. 

The constellations each occupy their own magical domains, as evidenced by the observable energies that emanate from Mundus Stones and their ability to instil power into individuals. We do not know who erected these stones (which can be found across all the provinces of Tamriel) or for what purpose, but their magical resonance tells us clearly that each constellation's signature is quite unique. This raises questions: were the individual constellations deliberately formed by the Magna-Ge, imparting their essence into the trans-constellatory light? Is each constellation a window into a different Aetherial realm, such as Sovngarde or the Far Shores? [...] A survey of the Warrior stone uncovered strong Aetherial currents travelling from the stars into the stone and radiating outward, implying a cross-Tamrielic web.
- Mysteries of the Mundus Stones

Taking the Wells emanating power back into the stars with the constellations potentially being windows into Aetherial realms, creates the supposition that portals could be formed and that the Wells’ original purpose wasn’t to restore magicka but rather to act as gateways. While immensely interesting at face value this seems to have little bearing on my original question whether water could be used as a way to travel to different realms. However, there is one little curious tidbit of lore that can be interpreted as a connection to this:

“This is a treasure trove of Dwarven astronomical scholarship! The three orbiting spheres could be guardian equation-bodies, but we should at least consider the possibility that they are Dwemeric Aetherbell beacons.
- Amalien, Dwemer Star Chart antiquity codex

If the Aetherbells were used to dive into the ocean, it could be as simple as the beacons being light sources, but if they were used to dive why have star charts? What if these were beacons for starlight? I posit that the Graven Deep weather witch was used to force clear skies, while the Aetherbells dove into the ocean, and using the realm-travelling capabilities of the ocean as fuel and the starlight beacons and star charts as navigational tools, the Dwemer figured out a way to travel to both Oblivion and Aetherius. 

One final thing to ponder is the fact that the Dwemer knew how to create Temporospatial Claudications, where entrances on Nirn would effectively take you to a pocket realm. While more mundane explanations (like portals) could exist for how they went about creating these in the first place, it is not entirely unfeasible to imagine that they travelled to other realms via Aetherbells and then, from there, created doorways to Nirn to make the journey less complicated or taxing.

Ragnthar has numerous entrances spread across Tamriel. It is literally a space-out-of-space, twisted out of reality. Its physical location is actually unknown! Observations made within the site suggest it once was situated within the mountains of Hammerfell, but a precise origin point has never been determined. What is known is that by stepping across the threshold into Ragnthar, you leave Nirn. And no one knows why. For indeed, the greatest question posed by Ragnthar is: why? Why would the Dwemer expend the enormous amounts of magical energy required to remove a complex from known reality? I call this effort a "Temporospatial Claudication," literally a twisting of time and space.
- The Strange Case of Ragnthar

Somewhat relevant as well is Ragnthar’s supposed original location in Hammerfell, seeing as the Dwemer settlements in Hammerfell and Stros M’Kai are the ones geographically closest to Graven Deep.

Is space travel via water possible? I believe the answer is yes, if you ask the Dwemer.
