The map is mainly composed of symbols you don't understand, but which you imagine to be settlements or other points of interest. "Is this the Citadel?" you ask, pointing to one of the more prominent notations.
Matthais nods. "Yes. Ignore the other markers—little more than ruins now, I'm afraid. It is to here that I wanted to draw your attention." His finger comes down on the map, at a point some distance northwest of the Citadel.
"I don't see anything there," you reply. "Just bands of color—I don't even know what they represent."
"The colored bands," says Matthais with a smile, "denote altitude—the troughs and peaks of the land around us. So what lies here is a valley, a large one at that, hidden deep in the mountains. Your Valley of the North Wind, perhaps."
