Lately, I've been wondering about that question. Could Suiko be a post apocalyptic world?
Not necessarily after the end of our world, but after the end of the "old" Suiko.
Let's look at the evidence...
Short timeline: As far as we know, the first thing ever to be recorded in history is in Solis -2, where Harmonia is established. However, the events of Suikoden 3 take place in Solis 457, and we know that about 800 to 1000 years before the Second Fire Bringer War, there lived another race on Suiko, the Sindars.
We know that the Sindars had an advanced technology, and that they were independent of Runes. They used their technology in their everyday life to make it all easier, and compared to the technology of the current Suikoden world, they seem much more simple. In other words, the technology was far more advanced in the time of the Sindars, but it has decreased since then... when does technology decrease?... hmm...
Finally, we know that the Sindarians are no longer around. Legends say that they were forced to move around due to the True Rune of Change, however, all their temples and ruins are more or less destroyed... or at least pretty ravaged.
My thoughts are: Could the Sindarian race have been wiped out along with their cities, technology and the like? It seems pretty likely to me, however, there are evidence that may point towards that it is absolutely not.
