You Walk into a Room...

7 things to put into a dungeon room:

1. Dozens of jars, carefully sealed with wax, containing dried preserves
2. Someone has tracked dirty footprints across the floor
3. A banana peel
4. Remains of a furious fight, including dozens of tiny black arrows and black iron swords with hooks on the ends
5. The skeleton of a dungeon creature, much too large to have fit through any door
6. For a generation, monsters, adventurers, and others have left graffiti carved into the ancient wood beams
7. A makeshift cairn to an unknown tribal deity
