You walk down the stairs into the machine room.
The machine room is one of this house's largest rooms, as it fits several large-scale machineries and all the workings of a Charles Dickens book. Currently on display are two of the larger machines, but on the floor level there are a lot more.
You find this room quite interesting as you remember fondly helping your sister construct some of these machines, back then, things were okay. Back then, she didn't hate you like she does now. All these machines are memories of the past in this way, even if they're bittersweet.
You head to the bottom and head out the door to the airstrip.
