Okay, who's building this, and where?

[Bob Schroeck]

No, I mean, given that the illustration of the design is a cylinder, that the Old Ring is one end of the cylinder -- if it's got a smaller diameter,
it's like the neck of a bottle...

What you had originally illustrated would be something like one "floor" or layer of the cylinder -- stack multiple instances on top of each other to
build the design. But the last "floor" at one end is smaller and much more primitive than the others.
