If you continue exploring the Manufacturing Facilities / Operations Centres, until they have no more blueprints to give you, and you then keep on exploring them, they will eventually give you the following message:
"The research station contains a vast array of scanners and monitoring equipment directed at bodies of water throughout the system. It is searching for something designated “abyss”.
The scientists who worked here seem to have been comparing the transmissions associated with the Atlas to strange signals found within the water.
Before they went missing, the workers concluded that this “abyss” seemed to hold a similar yet distinct energy signature to the Atlas itself. Another power in the universe…
I examine the records relating to the abyss. They show a repeating pattern of sixteen energy bursts, music that emerges from beneath the waves.
Contact appears to alter individual personality and objectives, changing even the most devoted Korvax into an agent of some unfathomable power.
Infected Nanite Clusters appear to be present within the archives. I take some of them. It seems to be for the best…"
Is this plot related - or is it just an Easter Egg referring to the movie?
(edit) Afterthought - I found this on a Korvax world, and thinking about it, it’s possible the message will only appear on a Korvax world.
