We bypassed Proxima Centauri on our way to the Alpha Centauri Binary System. Proxima is a red dwarf star, and even the worst planets in the Binary System were far more easily habitable. Most of biological humanity does not even think about Proxima anymore. It is simply one of the countless number of stars where no one lives. It is a different story for cybernetic humanity. Proxima was the first star our earliest AI probe swarms explored, our first foothold in the stars. The AIs and their cybernetic descendents have never left. They built Proxima into their first Memory World, the location of their first independent storage facility for all the knowledge of their race. Proxima is a far more important system than most people realize, and that is why it is so heavily defended.
