Welcome to the World of Dungeons & Dragons

In the Dungeons & Dragons roleplaying game, you and your friends coauthor your own legend.

One player, the Dungeon Master, serves as narrator—describing a world full of wondrous places to explore and challenges to overcome. The other players create characters and immerse themselves in that world, making choices and rolling dice to see what happens.

Silly moments spawn inside jokes; epic battles leave treasured memories; and where you go next is entirely up to you.
