How about throwing in the Dreaming Dark for some good old fashioned psionic fun? It's been way too long since they went through that possession episode, and this would be an interesting renewal of the plot hooks that were planted so long ago. The Dreaming Dark's main goal is to infiltrate and gain control of Khorvaire from the inside so they can raise more of those damn monoliths to freeze Dal Quor's cycles, and a reboot of the Last War provides many opportunities to extend offers of 'defensive troops', 'supplies', and 'potent weapons'. All of which come with the millions of the proverbial invisible fishooks, of course.
On the other hand, the Dreaming Dark might have manipulated/provoked the Order of the Emerald Claw into a kidnap attempt, which they fully intent to help foil (not too much, naturally, it would be suspicious), and gain the trust of Breland/Karnnath for further insidious infiltration. Which probably brings up the interesting question: are Kalashtar Avaists who have also infiltrated the ship going to foil the Emerald Claw, or actually help the kidnap process because they know it's a Dreaming Dark plot?

It would be most interesting if they meet someone they knew from before, who has advanced quite a few levels to become a psudo-peer of the Angels. And then attempted to convince them to help him/her kidnap the princess too, Mordain-style.
