A bandit is an outlaw. Belonging to no clan, a bandit will resort to stealing and ambushing caravans to survive.
Dealing with Bandits
The outlaws are a real threat to your clan's trade. If left unchecked, they will become a real problem; ambushing your caravans, and stealing your goods.
One way of dealing with bandits is to explore your tula at least once a year. You will encounter bandits and be able to chase them away, or kill them.
Performing the Issaries the Concilliator heroquest is another way to limit the banditry.

To the Orlanthi, bandits do not fall under the Laws of their good King Heort. They are not kin, and can be killed without the worry of kinstrife.
