Swamped

You spot what looks like a toolset in a corner. They're probably for maintaining the machine.

And chances are, if used improperly, they can be quite effective at sabotaging it.

You quickly inspect them, and notice that one is quite cold to the touch. Perhaps it's to prevent the machine from overheating.

Well. The machine is pumping something, and it's unlikely to function as well if whatever it's pumping is frozen. You take the cold-tool and touch it to the pump.

The resulting noise is quite jarring. And the pump soon breaks, with a solid frozen mass popping out.

You don't expect that to go unnoticed for long. You rush back to the room where you left the priest and the lizard.

Now what?
