Dear Azalin, I've got a problem and I just don't know what to do. It's recently come to my attention that all of my friends are backstabbing liars, so I want to ruin their lives and see them suffer unimaginable pain. That's not the problem, though. I need more info if I really want to stick it to these guys, but I don't know where to start. How does one go about forming a secret police to gather the intel I need to utterly destroy them? Please answer, you're my only hope! ):
Hmm. Pleading to my tender feelings for help is a bit misguided my anonymous friend.
How do I know you are not an enemy of mine trying to get me to reveal my secrets?
That said, I will answer your question as vaguely as possible and by not really answering it. It takes years to cultivate a secret police loyal to only you. You are better off utilizing means of scrying until you gain enough power to threatened and 'award' those beneath you into absolute servitude.
