. . . you don't need permission, capitalised or otherwise. The Permission Givers on this board only have jurisdiction over stories which actually use the PPC brandname. Their approval would be decorative at best.

However, it doesn't sound to me like you want to create a spin-off of the PPC -- which is the whole organisation and encompasses many departments -- but of the Department of Mary Sues. I suspect by now you've got the hint that there are plenty of pre-existing departments which would fit the role.

However, if you did mean you want to strike out on your own and create your own fictional police force, which would hopefully have all sorts of wonderful quirks to set it apart from the PPC, don't bother asking here for approval, just go ahead and do it. Stick it to the man, that's what I always say.

(It isn't what I always say. But only for lack of opportunity)

You wouldn't happen to be the author of the agent Dusk Daybreak, would you? Because we (that is, Neshomeh and I, mainly) have been trying to get in touch with that person for a while now.

In response to your actual question, I agree with what's already been said; no offense, but there's absolutely no reason to create a new department like this. If you specifically want your agents to focus on Pierce's (and Hunter's) work(s), you could have them be Freelance Department agents who specialise in those authors. That said, I also don't recognise you (though my presence has been spotty for a while now) - are you new or a long-abesnt oldbie?

A) Sorry, but that already exists: All-Purpose Department. They work with continua, not with types of badfic.
B) Are you too new or too old? Because I don't remember you either.
In case you're too new: Welcome! Leave your sanity at the door and enjoy this apple pie!

This seems to me to be pretty much just the Department of Floaters with a more focused... focus. To that end, we don't really need a new department right now, and in any case it's customary to wait around a month or two after introducing yourself before asking for permission to write a spin-off.

So introduce yourself, yes? Who are you? What do you like to do? Who is your favorite author? What of the PPC have you read before? What's your favorite spin-off? Have you done much writing in the past? Can we see some of that? That sort of thing. We really like to get to know you and have you be a part of the community as well as a fellow writer.

Also please take a minute to look over Da Rules, how to get Permission, the Original Series, and A Few Other Spin-offs.

I don't really understand the point of making a new department for something that is already done in other deparments.
You could just make your agents specify in that continua, instead of forming a new department.

Do you mean just kill badfic, or are you talking about, I dunno, unusually absurd stuff like Alanna the Lioness flying away on a winged Bluestar? (Also, kudos for Warriors canon. It's neat.) And no offense, but are you totally new, or have I just failed to notice you?

(I have no actual influence on this. I'm just curious.)
