The Binder of Fate

The mover and shaker in this case is an individual who has mastered the secrets of the Scoungers who follow the Prophets around everywhere, the Hushers and the Wizards. He makes a pair of Goggles that allow him to see who is significant to a prophesy and who isn't.

The long story short of the situation is that he is determined to thwart a prophesy to prove that there it is merely a by product of people's beliefs, rather than a force on its own. He will start by outright killing several of the principle people involved in the prophesy, only to see the significant players shift. He then turns one of the princples involved into a mindless vegetable, and finally just assembles a gigantic army, playing on the tensions between Spielglas and her neighbors to invade the city states, taking them one by one until he has a massive force not seen since the days of the last empire ready to lay waste to the city.

He avoids several small threats and assassination attempts the prophesy moves in his way, because he can see them coming with the goggles, until Fa just gets sick of the whole thing and just fries the army to a cinder.
