Sorry if this has been said before, because I haven't read all the thread as there were a lot of comments. But I think this is the moment to point something very relevant to the story.
One year ago I observed that a group of systems form a sort of line. I don't have the game running to see them in the map of the galaxy, but I'm talking about Robigo, Takurua, Almagest, Sothis, Ceos... all of them are pointing towards Formidine.
I honestly think that those systems were the beginning of a much wider project of colonization and terraformation, of which just the first ones were made (Sothis, Robigo). When I saw the colonies in EAFOTS, I thought it was coherent with that line. And now Zurara, next to a terraformable planet. All of them have relation with Sirius Corporation.
That makes me think that the plan was aborted. Zurara ended its mission (literally), and they didn't continue. The planets were abandoned, nobody continued the work. If so, all the planets would have been terraformed. Even more, I could guess that the colonization program may have continued across the RR line. Towards where?
And that makes me think. If it was a part of a bigger plan... was the plan to escape from the bubble? To create a route for humanity to a safest place to escape from a hidden menace? Was Sirius Corporation responsible of what happened with Zurara?
And why that line? Is there something at the end of it?
That makes me think. Nobody knows what Raxxla is. Some people says that "on Raxxla there are alien structures which serve as gateways to other universes."

I'm not thinking of universes, I prefer to talk about galaxies. There are old legends of eight galaxies. They may have a bit of truth. It seems reasonable that at the end of the RR line you may find Raxxla, a portal to escape from the milky way to another galaxy, a new place for the humanity to start from the beginning, in the case things go wrong here in the bubble.
If there's something, does it exists? Could a commander find it?
I think we should focus on the end of the line.
