I found the waterfall near the southern edge of the city, just inside the curved wall of the atmospheric dome. As soon as I found it, I activated my jet boots and flew over the foaming river below the falls, then passed through the waterfall itself. My haptic suit did its best to simulate the sensation of torrents of falling water striking my body, but it felt more like someone pounding on my head, shoulders, and back with a bundle of sticks. Once I’d passed through the falls to the other side, I found the opening of a cave and went inside. The cave narrowed into a long tunnel, which terminated in a small, cavernous room.
