It wasn't always there? My mistake then, and thank you for correcting that for me. Well, that does explain the "How did that not suffer the storm" angle.

It still doesn't really explain though why a people whose entire culture revolves around reeds, would build such a large settlement over a river that flows too fast for reeds to grow in it? Or.. why that sidequest would result in the spontaneous building of a town that is larger than all their other settlements combined? I mean, that place could rightfully be the capital of this zone now, by size.

P.S. If they have time and resources to build all that, someone should go fix the stairs to the southern part of the zone already! xD
