Rawena cocks her head to one side like a dog who didn't quite grasp a command.
"I'm not sure I understand the source of this hostility. As you yourself said, the information I've given you has proven to be true. And, had Harper's grandmother been a true enemy intent on destruction, my actions would have saved his life. Whatever your frustration, it is through no cause of mine." Then, almost as if she heard your thoughts, she changes her appearance, shifting from an ethereal decaying corpse of a withered, bent old hag to a nearly corporeal vision of grace and beauty. This image is the same as you've seen her present before, but it seems like she's taking extra effort to appear alive and real, or at least less undead. You feel like if you were to reach out and touch her, she might actually be there, despite her overall lavender hue.
When she speaks again, the haunting quality of her voice is gone, replaced by a deep soothing and melodic alto. She smiles gently, "Maybe this will help soften your tone." She begins to sit, and a simple chair appears beneath her.
"I never suggested that our alliance was anything other than one of convenience. My goals can be accomplished in stopping Thalnoth. The nature of the relationship between Ur-Quan and the Duke is... murky, but I might have a little insight into how that magic works. Bear in mind, each curse is its own concoction; no two are just alike. And, I've never placed a hex of that nature, so I might well be wrong, but I suspect that if one party is killed, all the stolen years would instantly come rushing back to the other. I believe that I can absorb that explosive release of curse magic without dying, as I'm already dead. Even if that act causes me to cease to exist, that would be a fate preferable to my current limbo.
The only thing I know of the dark sorcerer's power is that it comes not from study of the arcane. It comes to him from... elsewhere, though I know not how or from whence. We were not close then, and, as you can imagine, are less so now.
As for the dwarf wizard, I know nothing. That teleportation magic with the earth in the circle, however, is ancient. I'm surprised it is still in use, and, personally, can not see the benefit of using it as opposed to something more convenient.
We can address my goal of regaining bodily form and joining the ranks of the living after we stop Ur-Quan. What good will a new life be if there is no world left to live it in?
So, what are the possible next steps for trying to foil our enemy's evil plan? I can humbly offer one dead old lady's view on which course is best."
