For the Prolouge what I was thinking was that the City was Infiltrated with Nazerene Assassins. A rooftop battle was fought when the Assassins were cornered. You guys introduce your characters and their place in the city as this rooftop battle begins. A single Nazerene assassin is captured alive. The Sycophant tortures him and extracts the information that only half the Nazerene Army's strength approaches to cross the river as the other half is marching north after destroying Sidon in the extreme south and will not make it for a few months.
Then we shift to Antioch's Army and the Battle to prevent the Nazerene army from crossing the Golden Dragon at the stone fort.

Also Give me Feedback: Am I exerting too much control over story? Do you guys want to do this some other way?
That sort of thing.
