From publisher blurb:
Includes 6 fifth edition one-page adventures that are designed to be modular. What does that mean? It means that you can easily toss them into an existing setting, regardless of its theme. As the Game Master you can choose to make them short side quests from your normal game, run them as a one-shot, or add content to extend them to a full adventure. While the encounters and situations are set up to be a complete story, you can add additional rooms, characters, or encounters to each one to twist and shape it to best fit your GM style. You can easily change out the monsters and trap damage listed in the adventures with something similar that is level appropriate to the party. If you are unsure, consult the table in the DMG on pg 274. It provides the damage ranges appropriate to challenge rating levels.
