Every room on the site, drawn where it stands in the engine. The clock tower in the middle is the Loom; every street passes it. Heights are how many times a room has been worked, brightness is how recently, and a stone sits under every room that was standing before the record opened. The weather is the live chord. The plain list is underneath, for anyone who came for a list.

Drawn from the engine's own record on every visit. The map is one way of looking at the city. It isn't the city.
