Here is the Sihedron Temple in Xin-Shalast, from the Rise of the Runelords adventure path, with and without grid.

Scale is 100px to the five-foot square.

This area is not really detailed in the adventure path. If my party chooses to venture there, they will encounter the Immortal Ichor of Lissala, plus a few minions I haven't settled on yet.

Made in Photoshop, using textures from textures.com, a few assets from dundjinni.com, and a fair bit of elbow grease spent on making the shapes as vector images in Inkscape for use as masks in photoshop.
