Hallo! This setting sounds like so much fun that you've finally succeeded in making me consider joining an online game! (Not that I have anything against them; I just usually tell myself that I have other things I ought to be doing.)

What is the protocol for pulling a character from a particular point in their canon prior to the endpoint they're currently at? I'm thinking of apping John Constantine, but I'd like to muck about with him directly after the "Empathy is the Enemy" storyline.
