I see the stranger tap tentatively at the portal's control panel. They open the gateway and walk across the threshold. As the foam settles, another being approaches the still-active portal. A traveller, their face obscured by a blinding light. They follow the stranger into the portal's blue light. The structure's ancient stone bends and warps, buckling under some extreme force. At last, the traveller re-emerges. The portal closes. There is no sign of the stranger. Though this is a recording, I cannot help the feeling that the traveller has noticed me. I close the terminal quickly.
