The Bristolian Republic is centred around its capital, and the second largest city in Europe, Bristopolis, a metropolis of massive size and might, a mecca of technological advancement, economic activity and cultural development. Bristopolis itself is divided into four Urban Zones. Surrounding the metropolis, lie the poorer districts and further out, rural zones. Rural Zones are those which have higher regulations on building, and their main priorities are production of food in large bio-farms, which produce huge quantities of produce for use in the city, and to be shipped abroad.
