Parkville was near Arnwick, a city with 200,000 people. People from Parkville moved to Arnwick to find jobs, and they needed places to live. However, it was expensive to live in the city centre, so the government built flats outside the centre. Soon, Parkville became part of Arnwick, and Arnwick became a city with over a million people.
