Not that anyone cares but... Arc List.
First Movement: Skyward Ho!

Third Movement: The Chase is on!

Fourth Movement: Trapped.

Fifth Movement: Escape.

Sixth Movement: The Black Box.

Eighth Movement: Laplace's advantage.

And that's the end of Escher's Box.
Ten movements, and that's it. I've got an actual plan, a resolution, a couple of villains, and plot threads for another game, if we actually finish this one.
