I think the art is really cool. The description of the goddess idol and Corlax the Smith creates some memorable imagery. The room descriptions create a really unsettling atmosphere of what could be going on here. It's eerie.
However, I think this arcology feels empty. Presumably, there's acolytes and 6-armed Spellforged walking about, but I did not get the sense when I read it. Reading this reminded me of the Conan story The Slithering Shadow. Conan wanders through a city where everyone is a passed out lotus-eater. This adventure feels like the heroes entered a long abandoned place and are moving about discovering its oddities. Mentioning what acolytes are doing, what transformations are actively taking place, how there's screams of agony from the dissection theater, or the intonations of meditative prayer would help make this place a little livelier.
The font choice hurts legibility. I think that font works best for headings or short blurbs. For the long writing, consider a font that has more balanced lines.
