Below are the Patreon files that I did for Columbia: City of Secrets. Columbia, Maryland is a fascinating place. It’s an artificially constructed city that doesn’t feel like a city, lots of people live there but there’s no real overarching vibe coming from the place, and you can absolutely stick an occult conspiracy or secret cult somewhere inside city limits and nobody would ever know. It’s perfect for a certain type of RPG campaign, in other words.
