Hmm. Well, I could shuffle everyone onto Big Plot threads with a push here and there, to get us off the current mix of Big Plot / little plot.

Some interconnections evolved interestingly. Mal's threads started out 99% player-created but picked up ties to other players and metaplot on the way. Many other personal PC plots happen to mesh very well with other things I had in mind. And I was amused to the point of laughing out loud, for real, when Sakura charged full speed at a clue (Oberon's casual reading material) I thought everyone would ignore.

I can mention the more obvious important things without giving anything away. Sakura's on to one potential Big Plot thing. Nicholas and Michael touch on others; that doesn't necessarily mean the Pattern blades, though those may contribute in certain ways, depending on circumstance and knowledge. Those who dabbled in Powers have certain opportunities ahead, and not all possible Powers have been exposed in gameplay yet. From the Mal/Cornelia threads, the Map is a clue to one thing and the sword is a clue to another completely different thing. There are also other hooks and clues that haven't really been explored yet.

Much potential still exists for player-vs-environment, and in some cases player-vs-himself/herself. Some of the PCs have such a precise combination of personality and abilities that I get creepy "Oberon planned all this, didn't he" vibes.

Sakura and Michael are on one path.
  Nicholas could join them, or go do something else.
Malserrin would almost certainly end up on another path if he recovers that mystery blade.
Cornelia's shadow research leads directly to another path.
  Lysandra seems likely to end up pursuing the same things as Cornelia but from a different angle.
Riza and Vincent, as recent outsiders, could be set exploring something.
  Nityana, an insider, might end up searching for the same thing by different methods.
