From SRD's GI:
Peter Purcell: I was interested in your response to the magic Mordant's Need vs. magic in the Land. As an author, you are focused on the *story* you're relaying and magic-used-as-a-metaphor. As a reader we get absorbed in the story but fall in love with the *universe / world* you've created. I think that's why you get so many questions on the "rules of the WORLD" that are irrelevant to your author's perspective that the *story* should be the only focus. [Although you have said that maintaining internal consistency is important to you so that it does not distract from the *story*.]
Am I on track? Does it matter?! (smile)
Peter
I don't consider "rules of the world" questions irrelevant at all. But I get confused (and sometimes exasperated) when the questions don't appear to respect one vital distinction: we're talking about "rules of the world THAT I MADE UP." If the questions don't pertain to, or aren't validated by, material contained within the boundaries of the story, I can't answer them.
(And here we have another interesting difference between the "Covenant" books and "Mordant's Need". In "Covenant," the Land clearly exists in a different kind or order of reality than Covenant's "real world". In the Platonic sense, the Land is *more* real than Covenant's "real world." So characters from Covenant's "real world" can expand into the Land, but characters from the Land cannot shrink into Covenant's "real world". (emphasis mine) But in "Mordant's Need" the differing realities accessible by Imagery are all pretty much equal, or are "real" in the same way: they may run by different rules, but the substance of one can exist and function fully in another.)

Based on this, I do not believe that Joan is influenced by a Raver in the "real world." However, Covenant correctly believed that she was possessed in the beginning of 2nd Chronicles, and both Roger and Linden believe that she is at the beginning of Runes.
I'm at a loss to explain Joan's insanity/possession, in light of what SRD says about character's "shrinking" into Covenant's world.
