There's a woman sitting at a table in a bar.
The table's surface has to be mostly inferred; the majority of it is covered in an organized arrangement of trays, and those in a further arrangement of devices of a variety of appearances. Some have visible circuit boards, or screens, or wires. Others resemble metal spheres, or plants, or clouds of mist contained in an opaque membrane.
The woman occasionally looks them over. Occasionally changes the readouts on a projection suspended over the table. Otherwise absorbs herself in another handheld device, this one a tablet with a screen, the style of it matching the closest to her blue-grey sort-of-uniform, the metal pendant around her neck.
The table is in view of the door. At regular intervals she stands, walks over to the door. It disappears. She returns to her seat.
