My firmest idea is a fantasy involving six characters on a quest to save their respective realms. The story's going to be less about that, however, than the relationships that develop between them. So I guess it's sort of a fantasy romance.
Yes, there will probably be sappy love scenes and the standard overblown fantasy battles somewhere in there. I can't help myself. :)
I'll probably end up posting my NaNoWriMo stuff on a custom lock in my writing LJ, writersgrove. If you want to be included on the lock, let me know.
