The blue beam points near the top of the mountain range, into the cloud cover.
The hike is shorter than you think, and in a few hours you have already reached halfway up the peak. The sun is setting, though there is enough light left to reach the top before nightfall.
The group is tired from a hard day's walk and sets up camp. Knife continues on, alone.
Another hour and you reach the top. Night has fallen. The stars shine delicately in the sky.
The beam fades down into a dark cavern.
What will you do?
