Since I was sleeping after Lantz gave me an answer, I'll finally respond to what he said to my questions...
You just danced around my questions. All you really said was that the Dragon needs someone to defend him. You won't even build up the dragon's character, or give a better explanation of your dragon's character.
Q. Why does it feel like it needs to be protected all of a sudden?
Q. If you're writing the dragon's dialogue, what's his personality like? You said that minor characters should have a better spotlight. Could you flesh out your dragon focus?
Q. If you wrote your world from before CM3, why didn't you write your world around it?
You could've kept updating your world as Nasu updated his, and establish your world around the loopholes Nasu had to create your world. Hell, Run could still be the head of MA if you create a future event that was plausible enough to allow her to be head of the MA (despite barthemeloi, mega 2k magus, all other competitors for the position).
