Puppet policy is as follows:
If your puppet is active at any point, they can stay. If you want to have more than one, then they should be active at some point. If you want land for your puppet, you have to RP the acquisition of that land.
Pretty simple. Don't use the region as a place to store 50 puppets that don't do anything other than harvest people for no reason. Use the region "Atlantis" for that
Other than that, we're a very common sense region. If you use common sense, you probably won't be breaking any rules.
