If I may intervene.
Unless this thread is going to take place AFTER the next one I have planned with Thorok's character: Mazaloth, it wouldn't make sense of him to be involved, as Nevira has not yet awakened the Hellwyrm from his ancient slumber. (Bear with me, I was planning on starting that one today)
Also, I DID have an idea about this event that I wanted to throw past you. In the current thread Saving Grace, Vaia, Rylzyr and Mortum (possibly Rathen but he's been inactive) Are situated in Ketra. The idea was for another thread to start taking place directly after this one, where the trio leave Ketra to go confront the culprit who tried to kidnap Vaia. I was thinking this same culprit (A villan I'll add to the roster soon named Nazix.) Will confess his plans to Vaia once they defeat him, and during this thread is when your battle takes place in Ketra. They come back to the smoldering mess, which will probably be when more of your characters meet Vaia, and it acts as a huge kick in the butt for her, realizing what exactly her "destiny" is so to speak, and then we get into the good stuff...
Like reviving Mithril Fire.
