The machine room is at the back of the Obmunjalae vessel. The two prominent machines found in here are the crystal core assembly and the primary air propulsion engine. The central tower that reaches to the ceiling is the air inlet for the engine, connecting via the horizontal tubes to the pair of nacelles on the outside that provide the vehicle’s forward thrust. Two smaller towers draw power from the crystal core for distribution to the various pieces of magically powered equipment and lights throughout the Obmunjalae.
On the right of the picture, behind the cabinets, is a redundant set of the pilot’s controls. In case of maintenance or emergency, the ship can be controlled from within the machine room.
New to this iteration of the room are the aforementioned power distribution towers and pilot’s controls, more details in the crystal core, a second floor deck, grated flooring, and some adjustment to the two bridges that cross over the horizontal tubing. Here’s an image of that sparser room from earlier on:
