You convince Sensei to lead the way into the darkness to the West. You hold his hand to make sure you don't get separated. After around ten steps you can no longer feel the breeze from earlier. Another fifteen hesitant steps forwards later, you and Sensei reach a wall. There is a cuboid sticking out of it at (his) chest height, with wires leading upwards out of reach. It seems to have a removable cover. Following the wall a few paces to the North, you find nothing. To the South, you discover something large, strangely shaped and entirely indeterminate in function or identity. It's probably another piece of machinery.

You feel rather frustrated by all this fumbling around in the dark. You choose to express this by screaming abruptly. "Aaaaaaaaaaaaaaaaaaaaaaargh!" You scream. "Aaaaaaaaaaaargh?!" replies Sensei, more than slightly startled by your outburst. "Aaaaaaaaaaargh! Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaargh!" you explain. You feel slightly better.
Suddenly, all the lights in the room flicker to life and turn on. Once your eyes adjust to the brightness, you take a look at your surroundings. The two of you are in what looks to be some sort of factory or warehouse. The space you're in is square, roughly fifty metres to a side, and around six metres tall. You are on the West wall, near the Northwest corner. There are several conveyor belts running from West to East, with large, inscrutable machines on top at odd places. None of it looks to be in operation. The North wall is lined with five of the semicylindrical things you saw earlier.
Every available surface; the floor, walls, machinery, even the hatch in the floor you came from, are covered in elaborate diagrams drawn in chalk. There are various sets of concentric circles in places on the floor, with many other shapes orbiting them. Everything is linked by a network of lines. The lines are all drawn at right angles, like wires in circuit diagrams. Text is written in a few places, but you can't recognise the script. Most of it is written in white chalk, with patches of red and black, especially around the circles.
You only just notice a human figure sneaking up on you from the Southeast. A remarkably androgynous person, dressed in close fitting white clothing, is stalking towards you, wielding a large, straight piece of metal - probably an axle or piece of piping - in both hands. Sensei doesn't seem to have noticed yet.
