The No-Metal Construction Rule emerges as a defining architectural mandate in the post-Catacendre era, mandating that all buildings be constructed without metal to prevent Allomantic interference. This restriction reflects the new world's adaptation to the dangers of Allomancy, replacing metal with brick, clay, and wood while permitting only aluminum for essential modern amenities like lighting and sound systems. The rule represents a fundamental shift in how society balances technological progress with the need to neutralize the metallic arts' potential for destruction.
