I haven't got it fully fleshed out yet, but what I'm picturing is a fancy (anonymous) invitation placed in everyone's mailboxes, "You are cordially invited to the first annual Animus masquerade etc etc," but have some sort of secret message built in that would ping it as resistance-worthy.

NO IDEA HOW THAT WILL WORK YET, but that's my idea. uwu And in any case, Guy is likely getting involved, so just follow him around like a puppy if all else fails, Asch. :|b
