So what is First Contact going to look like?
Either Grace decides to go home, or he dies on Erid. Either way, though, theres no way a bunch of Eridians dont decide to come to Earth to meet us and thank us for our help and learn about Earth culture.
Either way, by 2150 or so there's going to be at least a small Eridian colony on Earth, teaching us materials science and learning astrophysics.
What's THAT going to be like?
