Loved this, though I had a question about one of the ending (So Spoilers).
In ending 11-4 we get sent to Ash's Progenitor. That I get, what I don't get is how Esra says that "We have a new planet to explore" (or something close), wasn't Ash on our ship? So how did we get sent to different planets?

It's more of a turn of phrase, since you partially terraformed part of the planet, and only really explored a fragment of Trigaea/X'ir. Ash's progenitor crashed a fair distance from your progenitor, and the humans, x'irii, and machines are setting in a new post-terraform era, now their priorities have shifted.
Now you've terraformed a good chunk of the world you've explored and disrupted the societies, it's sort of like resetting your explorations back to near zero again.
