Thinking about the Antagonist (that's the Dark Elf in this book, right?), what's driving him to track down and kill the incarnates? What's really motivating him?
Can you think of anything that causes difficulties for the Dark Elf?
Was the archaeologist murdered during the theft of the prophecy-shield? (I'm thinking that theft is probably the event that kicks off the story, the First Story Driver.)
You might want to try using the Theme Browser to do your storyforming now. (On the PC version you can check off "Allow storyform changes" in the little dropdown in the bottom; not sure what it looks if you have Mac.) It really helps to look at the quads and see how they work together, knowing that since you have a Change MC:
- the MC Problem/Solution will be the same elements as the OS Problem/Solution
- the IC Symptom/Response will be the same elements as the OS Symptom/Response
Because of #1, it may help to consider an element for the MC Problem and OS Problem at the same time. For example, a lot of what you've written above fits with an MC Problem of Disbelief (disbelieving his own self-worth, denying his divine identity / destiny). But can you think of any way all the OS characters are driven by Disbelief? Are other incarnates skeptical of their own abilities and identities? Do the others disagree with Baldur's plan out of disbelief ("that's never going to work") etc.?
Then you can try that same exercise with other elements that might work like Avoidance and Pursuit. (For now, I'd say ignore the choice of Issues -- pretend all the Issues are still in play unless you're certain one isn't right.)
