I think it sounds stellar, excellent work on taking the time to alter the story so well. I always enjoy reading when someone has actually analyzed how the PC actions have impacted the events behind the scenes as well as made it personal for the players (the ordered magic item was a clever touch).
I know it will be a long time coming over the course of the whole campaign, but I really want to know how the Revenant Nualia plays out. Even if it might not always be interacting with her, there are a few points they could come across traces that she has been in an area recently.
Kudos for your hard work!
