The crumbling concrete spans of old, above-ground train bridges are where we built and maintain the pirate satellite links to connect our tiny corner of the Matrix to the rest of the world. The ground-cable connections in the Rox are few and unreliable, damaged by the forces of nature and left to rot by the city workers who put them in place. Part of the work of our tribe is maintaining the web of fiber-optics stretching out from our territory and connecting us to the world. The satellite links give us the best Matrix access in the Rox, something valuable to the right people. One of the commodities the Netwalkers have to offer in trade for the things we need to survive and prosper.
