Eventually, it is revealed that in this version of the Fermi paradox, sentient life is endemic throughout the universe; Humanity simply hadn't noticed it earlier because the universe destroys any race before it becomes advanced enough to develop a Type IV civilisation. The story ends with Malenfant helping the Gaijin build a shield to prevent a pulsar from sterilising a large part of the galaxy. Although this project will not be completed before another predicted pulsar event wipes out all extant species, it is hoped to give the sentient aliens who develop from the aftermath of the coming extinction a better chance at long-term survival.
