Dungeons and Dragons

Dungeons and Dragons. A role playing game with the Dungeon master, the one who guides the players through a quest, and the players, the ones who fight monsters and have all sorts of misadventures. A fun, silly game to play with friends. That's all it was to Fionna Esten, who grew up playing it with her father and brother.

That is, until she starts playing the game with her friends, and they get stuck in the actual world of monsters and magic.
