Voyages of discovery? (spoilers for all RotE books)

[Nuytsia]

It is a bit strange that dragons do appear to only live in this part of the world. But I agree that it seems they DO, otherwise surely the apparent virtual extinction wouldn't have happened.
Why they don't range further? Maybe they actually cannot undertake such a long flight over open ocean. I get the impression it's a LONG way over water to the areas we haven't heard about yet.
Otherwise, it could be the memory stone requirement that you mentioned. I wouldn't be surprised it if only occurs in this area. Heheh I hope Robin Hobb doesn't explain the intergalactic origins of memory stone... gives me bad memories of the later books of sara douglass in the Axis series.....

Yeah I am not sure why the liveships seem to be able to go as far as Jamailla but there seems to be a big cutoff right there. What's on the south side of Jamailla? I may have missed something but it never seems to be mentioned.

Oh also, I am not discounting the possibility that Gernia exists in the RoTE world!!! I never considered it, as it 'seems' a very different world. But there's nothing stopping it really, as there seems to be no contact between the RoTE world and whatever exists way over the ocean.

Chade *has* discovered gunpowder at least.....

Now, dragons have reappeared. They are capable of tremendous long-distance flights and have memories stretching back centuries at least. Surely they have crossed the oceans and ventured beyond the known world?
This raises another issue; why did dragons go extinct worldwide?..........If other populations did exist, why didn't Icefyre (or, later, Tintaglia) attempt to contact them? Perhaps they were perceived as too hostile.
On the other hand, perhaps dragons were very geographically limited. They clearly have an obligate symbiosis with memory stone. Perhaps memory stone is limited to a particular geographical area. This, in itself, would be interesting. Where did it come from? Is it the remains of an asteroid or crashed spacecraft or was it generated by some very rare and specific natural process?
In any case, it seems likely that the world is about to expand. Surely some dragon keeper or liveship captain will want to know what is on the other side of all that water and where do serpents go to feed?
