Three days north and east from the second corridor.
The terrain rose into high country—a mountain range the Guild's maps showed as uninhabited and unmonitored, the substrate below it under compressive geological pressure from the range's weight. The ancient network here ran deeper than in the lowland drainage country, the original stages built to withstand the compressive load. Soren read the substrate character through his equipment from the range's lower slopes and showed Kai the numbers.
"Denser staging than the second build region. More compression. The ancient grammar here will be operating at higher load tolerances." He marked his notebook. "The fourth Source Point, at this terrain's construction depth, is probably in metamorphic rock rather than sedimentary. The grammar will be adapted for the substrate composition."
