floating light

I went back to the dock and then to where it met dry land. I couldn’t see very well, but I murmured, “Akari,” flicked my wrist, and created an orb of glacial green light in the air over my right shoulder. Green was a good color for this kind of work. The mortal eye can detect more shades of green than any other color on the spectrum.
I cast back and forth, but it took only a few seconds to find what I was after: a depression in the accumulating sleet, the marks of the passage of many feet. “Carlos,” I said, and pointed at the ground. “Tracks.”
