Big City is the major city on the unknown planet that the party landed on. It is at the center of a hob of cities, each 1 days travel from the other. This is explained as a way to keep people from having to stay outside in the dark with The Walker. It is still not a large city, with a population of about 5,000. The most impressive feature of Big City is the ropes of magical light that form a glowing dome above the city.
