I imagine the spell Fog Hammer and talk about The Ghost City, a setting-within-a-setting for my Old School Essentials game. I mention Ramanan's character generator for Ben Milton's Maze Rats, Jonathan Harper's Ghost/Echo, China Mieville's The City & The City, Fred Hicks' Don't Rest Your Head, Itras By, and H. G. Wells' The Door in the Wall. Encounter table at www.plundergrounds.com.
