Given that we're not trying to profit off her world, I can't see her setting the lawyers on us :)
National intrigue does make for a good story arc, but I suppose it depends on how structured people want things to be. I've run book campaigns with firmly defined plots, and I've run player driven ones, where I'm about 2 steps ahead of the PCs and scribbling fast
Actually thats not quite true ... I rarely write anything down in that style, I just wing it.
I think to start with, city wide intrigue is probably going to be enough to keep people occupied. Politcal maneuvering between individuals, houses, guilds, factions or what have you. The social combat of the word softly whispered behind a languid fan, with perhaps occasional more direct activities.
For a kick off ... perhaps the big midwinter festival? Thats an excuse for people to mingle, attend gala events, etc etc
