The Scouts! Of course it would be them. Miri is a very busy woman. I wasn't imagining her exploring herself (either in the past or the future) but she knows people. Who know people.
I tend to envision the surroundings of what I read in far greater detail than is necessary (for instance, I have a clear picture of the landscape around Solcintra) but I have only now noticed that my imagination has not ventured outside of the city on Surebleak. I know it's cold; that's probably enough to put me off.
Should you all ever present me with an excursionary chapter about landscape I will be very tense, waiting for something dangerous to spring out.
