The Demise of the Elderlings (Spoilers for all books, especially RWC)

[Nuytsia]

7. I meant that I think the volcano is south and west of the Rain wilds, whereas the Mountains and Kelsingra are north and slightly east. I think that the acidy river probably turns more to the south in its course.
8. Frengong is the buried elderling city near Trehaug. I think Farseer already said that. Here's a question - why are Frengong and the city on aslevjal built like burrows, with all of the buildings interconnected, but Cassarick and Kelsingra are built more like `regular`cities?

7. I was wondering if we think that the journey to Kelsingra can be traced on the map that we had in the previous books, or if that map is just not meant to be taken literally. Map of RoTE
Do we assume they went up the 'Rain River' and when they got to the thing that looks like a lake on the map (the huge extremely shallow bit they went through?) they went along the eastern tributary (as said in Dragon Haven, although there are many inconsistencies with 'left' and 'right' and 'east' and 'west' in that bit where they get stuck and then go down the tributary that Tarman chooses) and that it IS the 'Gem River' shown on the map? Or possibly the Gem River is the acidic one, and they went down that tiny little tributary barely visible on the map but east of Gem River?
If Kelsingra is up the Gem River, I'd imagined the volcano being in the mountains directly north of that fork/big lake. That way, say the prevailing winds were from the north, the ash wind could be blown directly south and affect the Tarman when it was on the Rain Wild River and also the cities along Rain Wild River, but not Kelsingra which would be most east of the volcano.

8. why are Frengong and the city on aslevjal built like burrows, with all of the buildings interconnected, but Cassarick and Kelsingra are built more like `regular`cities?

This would most likely be due to either the function of the city, or climatic reasons.
Farseer pointed out that some were more specifically built to accommodate dragons within the city for formal interaction (administrative function of Kelsingra). Aslevjal seems a less likely location for an administrative centre as it seems isolated, however it may be there is a lot more of the world to the north (despite it being at the northernmost extent of the world in my head) beyond Aslevjal. So there is the possibility that long ago it was not isolated.
It does seem a bit strange to me that Elderlings wouldn't accommodate dragons in ALL their cities. Maybe climate did factor into it. The two cities that seem more open to the elements (to be confirmed?) are nearer to each other - Cassarick and Kelsingra. Climate may have been milder in that region in the past compared to Aslevjal* and Frengong/Trehaug which was closest to the coast. Not sure what the climatic issue would be there - maybe extreme heat? Or very high rainfall?

*I still see Aslevjal as always being somewhat colder than regions further south, even without Prillkops freeze, as it seems the climate is colder in north and warmer in south. Maybe it wasn't a nesting place for dragons but simply a memory stone quarry, as Farseer indicated. I now think that quarry is the most likely reason there's an Elderling city of Aslevjal.

Sorry to only keep picking out one or two things at a time...I can type about the things I don't have to think on too much but not enough time for me to have to 'ponder'...actually, I don't have time to do this either but I am addicted !

teehee ditto!
