Another set for Basic D&D, therefore covering levels 1-3 of the game, this module is slightly different than usual. While we are now, in fifth edition, used to anthology volumes with several unconnected or only lightly connected adventures to be played in short sessions (think Tales from the Yawning Portal or Keys from the Golden Vault), back in the day there were not very common. 

Shorter adventures were usually those that you could find in competition modules, designed to be played in one session in a competitive mode in the context of a convention or something similar. Therefore B9: Castle Caldwell and Beyond is a new idea. The module consists of five different adventures with the first two being connected but the other 3 being quite discreet. All of them are also designed to be played in one session. 

The adventures themselves are quite simple, as befits the low level they are aimed for, with the first two adventures being simple “clear out the dungeon” missions, but growing in complexity as the module goes on. What we also get here is a pretty nifty Clyde Caldwell cover… which I suppose is a must for a module entitled Castle Caldwell.
