So I sit staring at the sheet of paper trying to figure what any of them are doing. Even when all -- let's see, both sets of knights, the royal official and his men, the sorceress/thief and the band of sorceresses, and the cultists -- six factions all started out with clearly defined motives that are passionately desired.
Fortunately what this story smells of is dramatic irony, so I have the prompt: who could woefully mistake what someone else is up to? And the side-issue of keeping all six of them yoked together into the same story helps. And that I know there are two more factions involved, so I can herd them all toward where they can hook up with that one.
