Outward Bound
Moving up the slope, Alyssa is guessing that there will be a plateau or something from which to get a better view. When she finally reaches the top, it's not a plateau that she finds, but the view is amazing.
Alyssa is along the rim of a giant crater, easily 50 miles across. In the fading light, she can see towers and spires at various points, the closest nearly 10 miles away to the north northwest. There seem to be trees or buildings around the bases of the spire, but it's difficult to tell in the twilight.
Directly below her is a steep, jagged cliff face that drops down to the crater floor, the slope easing eventually. The climb down would be dangerous with proper equipment during the day. At night, alone, it would likely be suicide.
As the darkness deepens, Alyssa does spot a light. Two, in fact. Perhaps a mile or more away on the floor of the crater, is a small group of people. They're carrying glowglobes, or some other type of illumination. They seem to be walking westward, in a line that will take them to the edge of the crater. Tracing the path of their progress forward, Alyssa can see a ... deformity? Crack? Path? in the rim of this Great Bowl. It's about four or five miles along the rim, clockwise from her current position.
