Zanarkand's neighbours (spoilers)

[Dynast-Kid]

If you look around Spira, you will see many locations have ruins of a machina city. For example, Besaid island is littered with ruins. The Mi'hen highroad has several too.

Dream Zanarkand is based on the thoughts and memories of Zanarkand's inhabitants, right? Those inhabitants would probably remember those other cities' existances, although I don't know where I'm going with this one.

I was thinking about that too.
