Well, I've been in the throes of building stuff myself, and I have to admit I'm already making plans to go against the grain. While I don't plan on having an advanced or even magical "tribe," they would be a coalition of villages with walls, canals, and engineering feats not unlike the Romans. Given the relative stability of such a background, is such an idea permissible?

Absolutely permissible! Just remain aware that death rates will remain high, as would raids and natural disasters, and crops would therefore be unreliable to feed a high population. You'd probably be looking at something that is on a cycle of destruction and constant rebuilding. In other words, life ain't easy.

In other-other words, a character who feels relatively safe would have no reason to participate in this story. ;)
