Juries. Executioners. Judges.
Detect Crime: You can detect lawbreaking like a paladin's Detect Evil. This only applies to your ruler's laws, and if something is technically legal (loopholes, situations that aren't covered), you can't detect it.
Call for Backup: You have authority over the local watch. In a pinch, when you're in town, you have a 2-in-6 (increasing by 2-in-6 per additional template) chance to call d6 watchmen to your aid. When in town, you can also conscript d6 watchmen into your party; they follow your reasonable, legal commands.
|also works as rules for Captain Sam Vimes; i think that's kinda neat|
