Peril in Pinebrook

From the introduction:

Peril in Pinebrook is an introductory Dungeons & Dragons (also known as D&D) adventure designed for younger players, but it can be enjoyed by players of all ages!

Peril in Pinebrook contains four ready-to-play characters that you can use to run your first D&D game. The simplified rules allow a Dungeon Master (also known as the DM) to easily run the game without needing other rules materials or rules knowledge.

The suggested number of participants for this experience is one DM and four players, but instructions describe how to run a game for fewer players. If you have more than four players, any of the ready-to-play characters can be used by more than one player.
