in tetratopian genre-tropey fantasy fiction, the villain cities are bright crystal spires to show off how decadent and extractive their pseudo-aristocrats are, whereas the good guy cities are rows of concrete apartments to show off how much thought theyve put into designing optimal tileable living spaces
(in scifi, it inverts, because everyone is super rich so they can afford spire pods without that causing issues)
@TetraspaceGrouping stop stealing my ideas
Or we can just postulate rich interaction of tetratopia and niplavistan
maybe the good guys use brick or wood idk what standard peasant contruction would be like but i like the idea that they just discovered roman concrete and ran with it for the rest of history and modernity
