I don't think it has been established in the story that Dag actually died on a "northern continent" separate from the one neno is on. I hope not,
anyhow. Looking at the map, it seems there really aren't any northern continents - just islands:
I've marked the approximate location of neno in red. the yellow is a suggested "northern" location for the other bunch, which puts them on the same
continent, but to the north in some grasslands, near an ocean shore. I calculated the distance between those two points given the planet radius from
the canon thread, and measuring the distance on the map in pixels - it works out to about 5100 kilometers, or about 3169 miles. just a little more
than the width of the entire US. that's about a 127 day walk, at 25 miles a day. Not quite 4 1/4 months. Think "neno in Ecuador" and "Ben and
company in southern Canada"
Each pixel on the map shown here is about 43.6 km / 27 miles.
if that works for you all, then it puts BIAD's landing somewhere within 30 miles or so of the Ben Crew at the yellow dot, because he just crossed
Sslar's tracks heading inland towards neno. it's still a long walk between the two, assuming you don't have to cut a path in the jungle or wade too
many swamps, both of which will slow travel. Gonna need a rendezvous by vehicle, I think.
The Pitfalls of Do-It-Yourself Planet Building
I tinkered with my swap file to get this computer to make big pictures with Terragen. When I ran the file for neno in the jungle at the edge of the
city, I got a surprise:
All of the trees are suspended overhead. Those overhead tangles are the roots of the trees.
It seems that for whatever reason, the software thinks the surface of the planet is actually 69.8 meters "above" where it really is, so it set the
trees that far too high, since I told it to set them on the planet surface. I fiddled with the trees, and got them to sit on the actual surface,
rather than the perceived surface, and got this:
Such was my day in Adventures in Planet Building. Those are some BIG trees, nuh?
