The Nomads travel the open waters of the Pacific and Indian Oceans, and many make their home in the waters of the IICP.
Sailors, fishers, traders, the Nomads are all of these. They follow the currents to catch fish, they seed and farm banks of seaweed, they carry information and new hardware from port to port.
The wealthier families of the Nomads are also responsible for running the Floating Market, perhaps the biggest temporary marketplace in the world. It could occupy the port of a small island for a day, or sit out on the edge of international waters for a week, but to get in you have to have an official invitation from one of the Nomad matriarchs.
