It is unclear what kind of madness would make somebody want to make a hallway look like a column of stairs set on its side. Perhaps it was utter architectural excess. Perhaps somebody could walk on walls. Perhaps the manse's design required it.<br/><br/>Probably the last one, as it somehow leads to another location in the Fate Machine, despite not visibly lowering at any point. And indeed going straight forward for long enough that it should have actually taken you outside of the spire. In a way, the monitoring room isn't quite telling you anything new.<br/><br/>The manse is damaged, the engine is malfunctioning but working, but at least the device and the manse were made to operate if things went as badly wrong as they did here. You could try working the controls, but it's not quite clear how good an idea it is.
