Inconveniently, the other side of the portal is a balcony. It’s a very nice balcony, in some ways — it has a great view, and the railing is fancy ironwork with polished brass fittings — but it’s problematic for anyone wanting to move deeper into the dungeon.
The balcony looks out on a vast space filled barely-visible-floor to unknown-ceiling with shelves, full of crates, and the aisles between the shelves are teeming with robots zipping around on the floor and aerial tracks, picking up and putting down crates. It could easily be taken for a marvel of modern warehouse automation — if it weren’t for the fact that the robots, also all iron and brass, vent steam with every motion, filling the entire space with fog. And heat.
The balcony has five gaps in the railing — two are equipped appear to be elevators (without walls) down to the bottom, and three have aerial rails leading out into the shelves. There are no controls for the elevators.
