End goals are very much dependent upon individual player motivation.
While it's true that there is not likely to be a civil war or a bloody coup or anything of that nature, that is partially (but not entirely) because nobody appears to play that way, or to desire that particular outcome. It certainly is within the scope of theme for a very politically savvy character to dramatically shake up the board; in the books there were a few arch villainesque characters that were almost successful in that sort of thing, foiled of course by the plucky heroine and so on and so forth.
Very recently there was an attempt to poison the crown princess and her unborn child which was somewhat narrowly foiled; circumstances pointed to the king's mistress as one of the key figures in that and she's been executed for her crimes.
Currently there are two formerly sovereign duchies that have been demoted, their former subordinate provincial duchies elevated instead for Reasons, all within the past two IC years. It's a bit Game of Houses, but the kind of thing someone from one of those families could decide they wanted to fix.
There's a fairly hush-hush plan to go to the game's version of the Middle East in search of some kind of spell to repair the severed magical connection a lot of d'Angelines have with their founding angels - which may or may not be successful. In the meantime the College of the Occult could probably use some occult scholars of its own.
And there's a great big giant bloody war brewing on the horizon, of the kind that is liable to impact almost everyone.
All of the above have significant player involvement and contribution. Some of it is fall-out from character decisions. (The duchy switch-ups were due to really POOR judgment on the part of their then-rulers.) They may not be sufficient to give you personally an end goal, but it's not meant to be the sort of game that has win conditions, exactly.
Like Sunny said, there's plenty of niches and things interested people can play, and if she can't steer you in a proper direction I might be able to pull you into some things. (I play Reynard, and I'm about >< close to marching the country off to war. That'll be fun! No, really!)
