...but I'd like to say that a spin-off with an Agent searching for his/her/xir home continuum is something that I'd definitely want to read! ^_^

Considering agents can be from anywhere in the multiverse, from any text and non-text medium, I wouldn't say having a home is very important. And even when an agent does have a 'home' it can be sort of arbitrary. An agent that hails from Middle Earth may be very different from one lifted out of a badfic set in middle earth. An agent from a Middle-Earth-set romance fic may even be very different from an agent that hails from a Middle-Earth-set action/adventure fic.

Agents can be from unpublished works, original fiction... ANYTHING could be out there, so anything goes, really. As long as it's enjoyable and well-balanced.

But on the second item, asking questions is not pestering. That said, a lot of stuff can be found on the wiki and throughout

While asking questions might help you understand the PPC, it doesn't really get you involved in the community itself. Comment on missions and stories! Get into a (friendly) debate with someone! There are plenty of places and ways for you to show your viewpoint; we don't really see that with you only asking questions.

There are plenty of interesting topics on the board right now. Huinesoron's thread on deities and how they work across various continua if they're the same- and whether they might even be the same at all despite sharing similar roles to ones we are familiar with in the real world- is just barely getting started, and then there's the goodfic thread with a link to the PPC Rec Center and the fics that people find good in that particular thread already!

I don't see it as being that important to have a home continuum. What is important is that there is a consistent set of rules that govern your character. Who knows, maybe the search for their home continuum could be a major plot line for that character.
