Phaedrus, I'm assuming I'm supposed to report to somebody?
You weren't given specific names or descriptions, or even numbers, but there is a specific pass-phrase and answer that the... let's give them a name that they use for themselves... how about "Visionaires?" There is a passphrase and answer that the Visionaires use to recognize each other. Let's say it is:
"Seen any ghosts around here?"
"No, they only come out at midnight."
Or if one of you have a better idea, I'm all ears... for either the name they use for themselves, or the passphrase and response. Please feel free to just make stuff up as we go, and I'll roll with it, as long as it is mostly just fluff.
