So far that hasn't happened. Yet.
However, as a few other people have stated and much like Stephen King and Terry Brooks (a few examples that come easily to mind) much of my writing is all interconnected. Unlike them, however, my worlds are connected at the genre level.
What I'm writing now for Nano is a new genre for me (and something that has made some of my darling constant readers happy because they love this genre and I've hated it for so long!) so it doesn't connect at all with any of the other works that I've done. In fact I've even got a new psuedonym for this project.
However, aside from what I'm writing now, I do have a massive epic metafiction project that I work on occassionally that has but ONE new character in it. So far EVERY other major character in that project has come out of my other works (all of them) and has been twisted around a bit and then mashed together. Heck, one character even goes back to her ORIGINAL concept which was changed when she got written into another series. This project is sort of like my 'Dark Tower'.
The problem with this is that I'm sure the one original character for this project has his own project/worlds out there somewhere I just don't know what that is yet.
So in a sense...yes. And no.
Rabe...
