Flatland has directions just like we do: north, south, east , and west. They also have what’s called a southward attraction, something we would call a slight pull of gravity. Citizens of flatland use clues such as the rain, that falls from north to south, to give them direction. Houses in flatland are mostly pentagons. The law for houses is that if a city or town has a population of more than 10,000 people then all houses have to be at least a pentagon shape. The only exception to this rule is military buildings such as barracks and powder magazines. Those can be square.
