Planet A1-01 is essentially the first planet in orbit and the one closest to their central blue giant star.
Of course, that's only true at present.
In the past, there were over a dozen planets positioned ahead of it, orbiting much closer to their blazing mother star. But over countless years, the star began expanding—its core gradually bloating due to the relentless overconsumption of fuel—until, eventually, it engulfed the innermost planets in its fiery maw.
This devastating process forced the people living on those planets to evacuate, abandoning their ancestral homes and migrating further out to safer territory. As a result, A1-01 is now the most densely populated planet with these displaced souls—practically a refugee planet at this point.
Why am I talking about all this?
Well...
"You lot! Don't stop walking! We still got a long way to go!"
