Fill in the Holes
Now that I know the basic order of the events in the story, I have to fill in the holes so I know how my character gets from one event to the next. I do this by creating new events that describe each step, in a sentence or two, that my character has to take to get to the next event.
For instance, I might have two events like this:
Auren leaves the Dark Isle ~ Auren is captured by the Galvadi
Now I need to work out what happens between these two events. Where does Auren go when she leaves the Dark Isle, and how does she get there? What does she do when she gets there? I keep asking questions like these and creating events for each answer until I get to how Auren is captured. Then I do the same for the next event and work out what happens after she is captured, and so on until the end.
Then I'll move on to the next character and do the same.
