6.) Nomads
Players can also create Nomadic societies. These function very differently than normal societies. For one, they move. Societies may allow them to move through their territories or tell them to stay away.
Nomads don't have regular pops. Only soldiers and elites. When in neutral territory, soldiers can be sent to scavenge food and each soldier will scavenge two.
Nomads can still gain technologies like other societies and increase their population.
Nomads can attack settlements, conduct raids, and the like and become terrifying creations. When a Nomadic group takes a fort, the fort is converted into another horde under the control of the player.
Nomads can be hit with Plagues as well. If they're moving through borders of an infected society, there's a chance the Nomads have a soldier infected.
The only technologies the Nomads are affected by are Military and Civil.
