You are standing in an open plain. It’s dusk, and the sky is pinkish-purple-grey. In front of you are patches of boggy vegetation. You can hear some birds and insects and see shallow water, but the area is fenced off and you can’t reach it. In the distance, behind the bog, is a range of blood red mountains. You turn around and see a smaller range of chalky mountains. As you walk towards it, you can see deep gouges in the ground around you. When you look down through them, you hear a low, repetitive sound, and see a large cave, at the bottom of which a deep bed of dark water. You can’t enter it. When you look ahead again, there are clusters of shrubs and low trees on a dry riverbed. You choose this path and walk along it.
