Factions are the fastest way to make an OSR campaign feel alive—without writing a plot and without turning your prep into homework. In this video, I show a simple, table-ready method for building factions in dungeons and in the outside world using just a few lines: what they want, what they have, what they fear, and who they need (or hate). Then we walk through two concrete mini-scenarios you can steal: a dungeon with competing groups and a town with three powers pulling in different directions.

If you run B/X (or anything close), you’ve already got the perfect tools for this: reaction rolls and morale rolls. Used the right way, they don’t just decide “fight or not”—they generate bargains, threats, retreats, alliances, and consequences that carry forward into your sandbox campaign.

Try the quick faction checklist at the end and drop three factions into your next session. If you want more practical OSR tools—reaction rolls, dungeon procedure, faction play, and campaign scaffolding—subscribe for more.
