Located on the borders of Muddlemore, Pendulum, and South Gallia, the unthinkably large metropolis of Bastion is easily the largest city on Fronterra. Starting a small village on the banks of the Tibris river over a millennia ago, the Bastion metropolitan area has grown to be home to nearly 1.2 million people. The city is divided up into 30 separate districts, with each of those subdivided into many smaller burrows and neighborhoods. The old city is sectioned by its massive city walls that give Bastion its name, however the population outgrew those walls hundreds of years ago and has spilt out to claim more and more surrounding land.
