The passageway that leads to the systems chamber is big enough that you could drive a delivery van down it, but it’s not as straight or as level as the main entryway. It is mostly occupied by a conveyor system of terrifying power and speed, which is carrying tons of dripping grey muck out towards the main chamber to be dumped into the Goto trucks. In terms of apparent cost and sophistication, it bears the same relationship to a normal conveyor belt as an F-15 does to a Sopwith Camel. It is possible to speak but impossible to be heard when you are near it, and so Tom and Randy and the Kinakutan who calls himself Steve trudge silently down the passage for another hundred or so meters until they reach the next cavern.
