You know I always figured your rebuilding of Norende was really just supply gathering. Your gathering people, inventory, materials needed to build places, and planning out how all the resources should be distributed and the order in how they build. So that when the chasm closes all the work is practically done they just need to follow the building plan then populate the town with the resources and people gathered.
Or they are just building it somewhere else.
I've got a quote that embodies you perfectly, but it's seventy-three posts long, has a few massive flowcharts, and lots of Xion-KMA to Me
