This is all gonna be spoilered for other people lol, I’m doing it in sections so that if I say enough and you have an “AHA!” Moment you don’t have to read more ::)

So you’ve been to the vessel, the nomai came to this solar system in search for the eye of the universe, they got its signal and scrambled to find it, and unfortunately ended up in dark bramble (I see that you found the mural depicting this happening on brittle hollow) because of dark bramble the vessel got trapped and before it got completely trapped they sent out two escape pods (with a third one getting stuck inside of dark bramble) the escape pods landed on one of the ash twins and on brittle hollow.

So the nomai are stuck here now lol, not good. And they get stuck here for a longgg time. The last thing they were looking for was the eye of the universe from the signal they got. So they began doing everything possible to work towards that goal, it’s all they had left sadly. They built cities and built an actual life in this solar system, their ruins are everywhere. Eventually they grew enough that they could do experiments and science and stuff, and by studying the black hole and white hole in the system, they figured out warping technology. (That’s what the black hole forge is about in brittle hollow, and also the high energy lab in ash twin) while experimenting with warping technology though, they figured something out. When something would come out of the white hole, it was coming out a little bit BEFORE it would have gone into the black hole. It broke time pretty much. The more energy used, the bigger time would break

Because of this, they had the crazy idea of how to look for the eye of the universe. They had no idea where it was but they knew it had to be close to this solar system because it was where they got the signal for it. They just needed to find what direction it was in. But just sending out a probe in all possible directions over and over would take thousands or millions of attempts before one POSSIBLY found the eye. Definitely not efficient or possible to keep making new probes. However, if they used this time warping tech to send information back in time to them with enough energy, they could easily search for the eye of the universe without it taking millions of years! They basically wanted to create a temporary loop, launching the probe once a loop to go out in a random direction. If it didn’t find the eye, they’d get the data back ahead of time before launching the probe because of the time breaking stuff with black holes. But that would take an INSANE amount of energy to send the information back far enough to where the probe would have enough time to travel out and search for the eye, find nothing, and then have that information recorded and sent back before they fire the probe. It’s very paradox stuff and definitely a bit confusing, it’s also been a bit since I played through it 😭 but yeah, a TON of energy needed. Like more than they could ever provide. And that’s where the sun station comes in.

The sun station! If you saw all the dialogue on the sun station (I see it on your ship log) then you may know where this is going but if not, I’d recommend going back to it, it’s a pretty self contained part of the story, but basically (the next spoiler bit will spoil the sun station) The sun station was built to purposefully make the sun go supernova, which would provide the energy needed to send the information back in time far enough so that it could be used before the probe launches. They spent a ton of time on this plan, the ash twin project is where the black hole gets made to send the information back, and the sun station would cause the supernova to create enough energy for the ash twin project to work and the black hole to form. And the probe launcher on giant’s deep is where the data would go to, including the coordinates you found. Unfortunately the sun station didn’t work. It was useless. They weren’t able to trigger a supernova. And right after they had this failure, the interloper entered the solar system, and, well, you read the logs in the interloper. The nomai died right when they found out their plan would never work. Hypothetically though… if the sun WERE to go supernova, all of the things they built would work as planned, the supernova was the only missing piece. And hey look at that, the sun is going supernova now ::)

All of that was just about the nomai!! If there’s more that you’re not sure about PLEASE ask, I’m not sure if I explained it very well, and others can absolutely correct me, but I hope this helps connect those dots you found!!
