Finally catching up with this after a long glut of work—all of it excellent! I really like the bit about banning most forms of trade within sight of the temples—that could be exceptionally problematic if a temple is tall enough to overlook streets for some miles.

I'd like to propose the architects of the smugglery were from That City On The Island We Keep Talking About, which is probably mineralogically poor since it lacks the mountainy wealth of the lands around Umam. We need a proper rivalry and maybe a few Punic wars.
