E of truth just makes the fascist Watch more so because of the way it works.
I like it. I think ill include a city that has fully embraced the Thought Police/Pre Crime model in my next 5E campaign and watch my players try and dismantle it, since compelled confessions are pretty much the definition of Lawful Evil.
I have. It was a blast ; it requires a
large amount of spellcasters to work, but Zone of Truth has the advantage of being 10 minute long and working on any number of people. I had the population required each morning to walk through the Citizen Plaza and swear that they didn't break the laws the day before. Having 3 citizens saying "I swear" per round for 10 minutes can allow a fairly large population to be checked. Those who somehow couldn't swear were taken into custody in order to help them correct their antisocial behaviour -- one of the rules was of course that it was forbidden to ask about oathbreakers, who were granted their wish to engage on a pilgrimage of redemption (who, usually, ended in a moat right outside the city). For serious offender, a special version of Modify Memory was cast on the culprit's friends and family, that didn't remove the memory of an event, but of a person. "No, heroes, we don't know why you say our third son was unjustly killed. We only had two sons anyway. And we never lie, because citizens never lie." Asking questions about the inner working of the Watch is also, of course, forbidden.
For particular effect of pre-crime, you could also mobilize the 4th level divination.
"Will a crime, defined as breaking the Major Laws of the Citizens, occur North of Main Street? tomorrow? YES
"Will a crime occur North of Main Street and West of Citizen Plaza tomorrow?" NO
"Will a crime occur North of Main Street, East of Citizen Plaza, and North of Banker Street?" Yes
It require a cadre of elite spellcasters but pinpointing a block can be easy, opening the way to the preventive removal of its population.
Add that unhappiness was removed by alchemical substances in the Citizen's Aqueduct and that all that divination was powered by the sacrifice of people in the moat outside the city and you have a perfectly fine area to live in, where no crime is committed, everyone is happy, safe and hard working. And a steady supply of immigrants that would love to exchange their live of misery for the perfect security afforded to citizen of the Fair City (and lodging, since a block near Banker street was conviently conveniently empty today to be rented by the Council to the new immigrants).
I wasn't dickish enough to make the PC an elite cadre of agents of the Fair City. But I considered it.
