Kevyn accidentally started a fire. He is now both too unconscious and too low-to-the-ground to fully appreciate it.
The plume of smoke is over five kilometers high, and casts its shadow over 900 square kilometers of landscape.
It is visible to Kevyn's companions; whose march has taken them over a hundred kilometers away.
Smoke. That can't be good.
You know what I learned in my Space-Scout Fire-Starting Badge?
Where there's smoke, there's something making smoke. Not necessarily fire, though.
It is also visible from orbit. . .
With good enough sensors, it is visible from several light-minutes away.
From 25,000 light-years away, however, it is a little difficult to resolve in any detail.
Nothing. They might as well be on the other side of the Galaxy.
(For starters, you have to wait for light to travel 25,000 years.)
