Great point. I've also been thinking similar thoughts, some of the best storytelling tools are the simplest ones. What if you randomly get a "Special delivery" at the postmaster, and it turned out to be a note from a family within the city. It says that because of your efforts patrolling the cosmodrome, they where finally able to make it to the city. At the bottom of the letter reads "thank you guardian" in a child's handwriting, it also has one bit of glimmer tapped to it. Sorry, just blazed a little rabbit trail there.
