The overall authority is the Queen of course and nobody wants her acting in a heavy handed manner either as she could let all hell loose magically speaking. Crime rates are relatively low but, sadly, when it takes place it tends to be “spectacular”. For example Brankaresh murdered rivals to steal their spells and overthrew the Queen briefly and the Witch deliberately let a dragon loose to cause as much devastation as possible.
Village settlements tend to be well run - nobody wants to rock the boat and upset the neighbours. Though there is one exception to this. Villagers tend to unite in the cause of a decent planning dispute and it’s not been unknown for a local mayor making the wrong decision to face a very unpleasant fate. That’s the problem with living in a magical world. Almost any fate is possible!
