"Wait." Firo's suggestion makes Luna stop moving for a moment - she's forgotten for a moment that she does have a way to find the children, or at least figure out their general direction, but she has to concentrate to use the powers that have been given to her. It takes a moment for her to calm the anxiety still plaguing her nerves, but it does work. Once she's in the right state of mind she can feel them, like distant warm spots in her mind (though maybe that isn't such a good analogy given where they are).

"There are still some left inside here," she reports to Firo. "North of us, and a little to the east. I can sense them." She points in the direction they need to go. It's not quite where the next door leads, though, so they'll need some time to navigate through the building.
