D&D BECMI/ B9: Castle Caldwell & Beyond / Brookline RPG Day

Before bounded accuracy. Before character builds and subclass trees. Before the dungeon acknowledged your feelings about it — there was D&D BECMI. And it ran like this.

B9: Castle Caldwell & Beyond is a published TSR module running on the 1983 rules that shaped everything that came after. BECMI strips the game to its essentials: exploration, resource pressure, and a dungeon that will absolutely kill your character if you give it the chance. Gold earns experience. Torches burn down. Death is fast and not particularly dramatic.

Character creation happens at the table — no prep, no backstory required, no attachment recommended. The format runs comfortably at larger table sizes, so bring whoever you want.

Classic TSR module, run as designed
Character creation at the session — arrive empty-handed
High lethality by design: don't get attached
Larger table capacity: bring your crew

No experience needed. The rules are light enough to learn in five minutes. The dungeon, however, does not offer a tutorial.
