We walked into a strong breeze coming from the access backbone. I picked up human voices on audio not far away. From the feed activity, there was a lot of traffic about two hundred meters to the right, toward the plaza and the hotels. None of it sounded like emergency or security operations, just normal support system work. In six more steps the ramp reached the backbone, a shadowy cavern lit by low-level navigation beacons. Things whooshed by in the dimness, mostly lift platforms and automated carriers coming from or heading back to the port cargo depots.
