Located on the west coast of India, the group of islands which has grown into the city of Mumbai, was probably first recorded as the home of fisherfolk where a group of Buddhist monks established an outpost late during the Magadhan empire. The islands were tossed from one king to another emperor for two millenia, until the maritime trade empire of the British decided to develop the natural harbour into a city. In the four hundred years since then, the city has grown by a series of land reclamations which now link the original islands into one mass.

The core area called the "Island City" has the most expensive real estate in all of India. As a result, the city has grown far into the mainland both to the north and the east. It is not unusual for people to commute more than an hour to work each day.
