You find that the best keys are not often made of metal, sporting jagged teeth. Sometimes keys are a series of loops wound around a central core truth, or one piece of stone set so that your structure doesn't fall around you into crumbling dust and chaos.

Here, the light streams in brightly. A rather cinematic gesture, don't you think? You perch nearby to observe the passersby, each of them trailing a silken cord behind them. It amazes you that so many lines could cross and weave together, and yet never tangle or confuse the participants.

You take out a notebook, and begin sketching the scene before you, taking note of the detailed stone work.
