Nick was above a Containment Unit.
Due to security reasons, Containment Units didn't have their entire ceiling covered in glass.
Or, more specifically, the cheap ones didn't.
The expensive ones were made of materials either treated with Zephyx or directly harvested from powerful Specters.
After all, level three Specters and higher could basically break through any kind of material that was created in the traditional sense.
Since the materials were treated with Zephyx, windows, entrances, and walls weren't really any different for the expensive Containment Units.
The only difference was the price, and the difference wasn't even that big.
This Containment Unit didn't count as one of the expensive ones.
The Containment Unit was lit up by one window on the ceiling, about one-by-one meters wide.
