No this is not just for kingdom wars, although that would be a good way to use the system.
This would offer us a method to temporarily punish individuals for things. People who are "not" in your kingdom, must "not" be in kingdom mode, and "must" be on the island. Having this ability is just a way to better police your area, and to get rid of some nuissance who has not listened to the warnings and needs to be deported.
There would be time limits for how long you can jail somebody, so it wouldnt be to horrible. You wouldnt be able to jail non-kingdom members as long, but they would be deported apon release. Also, the ability to jail would cascade down the rank lines, similarly to how other rights function. So the king could jail anybody, while a General could only jail people under him. And how Zormite is set up, the Elder pretty much could jail anybody
except me.
