Yes indeed. Which means that if it is impossible to get food, everyone dies. If food is hard to get, some people die, and the rest are now able to get food. This happens within a few months or years after the Maghiz. After that, the recovery may take a long time, but people won't be dying in droves -- there won't be any droves.Peter,
Growing food is one thing.
Distributing food is something else entirely.
With the collapse of Darrian's TL13(1) transportation network and the complete lack of any "leftover" transportation capabilities beyond TL4, you can neither move the food to the survivors or the survivors to the food.
When neither the mountain or Muhammad can visit the other, the feces definitely hits the rotary ventilation device.
I'd like to point out that we have very little information about how long it took the people on Darrian to recover, except that they hadn't reached TL9 in -275. For all we know, they could have been TL4 and only recovered over the next couple of centuries with plenty of help from Mire.
The Rule of Man were generally TL12. There may or may not have been some TL13 technologies around.1 - I keep mentioning TL13 because, IIRC, that was the general maximum TL of the Rule of Man and thus the general maximum TL that the Itzin Fleet would have brought to Darrian. Darrian most certainly did advance beyond TL13, but I believe TL13 was the most widespread high-tech level in use, albeit used rather "thinly".
