Map an Ancient Mechanism

[XCali]

Here is the challenge:

Map an Ancient Mechanism, a room where a really old mechanism lies, with gears and levers. It can be a puzzle to be solved, either in forgotten ruins, between giant crystals, or in a chamber underneath a castle, use your creativity to come up with a compelling setting for this mechanism.

Think about how adventurers would come in and see this room.
Good luck and have fun!

I like the idea, but I think prompts get more participants the more broadly they can be interpreted (within reason). Maybe keep it more broad like "Map an ancient technology."
