I just need to say something about your claims in your post. You character isn't immune to the Creeping Death. That's kinda like saying someone with radiation poisoning is immune to more radiation. 
The Creeping Death is a magical force that grows and changes. 
The only reason I accepted your character, and the part where her parents lived with the disease, was because I assumed they moved far away from the CD when they got sick because you said they were nomads. (Also, reading back your CS, I wouldn't say elven genes are hardy, but that's hardly important, and I don't have a problem with her parents living as such.)
The CD is nowhere near Urenda, nor in that quadrant of the continent, in any serious degree, which is why mortals live there. I tried to get that across when I said the mortals all live in the still inhabitable northeast, but I never elaborated on it and for that Im sorry! (If any of you from the Original remember that the priests had thought that it was coming, that was part of another hook that I am still planning on using!)

However, because the CD is not in this part of the continent in any serious degree, she can totally think such and have 'proof' that it's true. While I likened it to radiation, I will say your character can have a resistance against its effects. If she had come across it at all in the area, it wouldn't have been that strong yet (because it started on the other side of the continent, which I didn't find too important, only that the northeast in inhabitable), and if she hadn't dawdled, would not have been made irreparably sick. Which, in actuality, does give her a significant advantage because they wouldn't encounter that potent of the CD anywhere nearby. 

Im working on maps, especially one that shows the extent of the CD, so I hope to clear that up!

I don't mean to nitpick you, I know I really come across that way, it's just that if they wind up leaving the area and going where the CD is strong, she can still get sick and die.
