Love your submission! As a local POI, it works well for any sandbox/West Marches-style game. I love that it is more of a liability that needs to be dealt with eventually, and the table of “Cult Activities” drives that home over a standard encounter table!
Also, I love your illustration style. I really need to get better at architectural illustration myself, so this is inspiring. The way you laid out the keyed locales around the landscape illustration is especially wonderful. Again, I’m inspired to break out of my columns and boxes looking at your work!
High marks!
