They travel to Neptune space, following a cryptic message left by Schön. Here they set up camp on Triton. Afra attempts to cure Brad by shocking him while he is being reconstituted from the liquid state, but the attempt fails and Brad is killed. Over time, and with further help from Ivo, the group watches a benign form of the entire broadcast, which they come to call "traveller". The liquefaction technique is only the first of many shown in the traveller signal, which describes an entire suite of technologies that allow interstellar travel. Using the instructions in the signal, they convert Neptune into an interstellar spaceship.
