The progressive Geshels and conservative Naderites (two fictional groups in the novels) who made their travels into the Way quickly met the Jarts. Conflict ensued in order to drive the Jarts out of the Way - this partly succeeded within the first century of Human expansion into the Way. Both sides fought each other through the use of remote slaved munitions carrier vehicles, of broadly similar design (a consequence of their shared environment). Human vehicles were 'manned' by partial personalities held within memory systems. Jart machines had similar arrangements, though in at least one documented case, one of the war machines was manned by a corporeal Jart duty expediter, subsequently captured.
