Peshwah after the Great Rain of Fire

That is definately possible, although it would have to only include those horses they brought over the Brun, since the Skothar Peshwah would need to have their horses intact to become the Jennite. Perhaps the Proto-Jennite found some clerical ritual that allowed them to save their horses?

Or it could have been entirely environmental. Perhaps the Jennite horses were able to survive by eating some plant that gave a boost to immunity from the Wasting, while the Ethengarians traveled beyond that plant's zone of influence. That's just one idea, but there could be a hundred more things that would work. Hmmm... In keeping with the general theme of BC 2300, I usually like to find some 'thing', or some explanation as to how a people managed to survive the GRoF and the subsequent Wasting disease. What if the proto-Ethengarians actually sacrificed all of their horses in some ritual in order to protect themselves from the disease? The proto-Jennites (whether the two groups were already split or not) would have found some other way to survive that did not require loosing their mounts.
