Sandbox Cults: Public Front, Hidden Power, Real Consequences  @TenkarsTavern
Uploaded February 2026 | Updated September 2026, 2 weeks ago
Cults are an OSR superpower… if you run them like a living faction instead of “robes in Room 12.” In this video, I break down what cults are at the table, where they operate (town by day, dungeon by night—often both), and how to play them as a GM in B/X D&D and other old-school games without forcing a plot.

You’ll get two quick mini scenarios you can drop into your campaign, the most common mistake GMs make with cults (making them too obvious), and the simple fix: give them a public front, a weekly goal, resources beyond hit points, and consequences if the party ignores them. I also give you an 8-step “Cult Quick Card” checklist you can use tonight to tie rumors, town play, and dungeon exploration into one cohesive sandbox.
