From the introduction:
Marooned on an uncharted island, caught between two warring tribes, and threatened at all hours by a dormant volcano prophesied to awaken again. Can our brave heroes discover the legend of Starfall Island before they fall prey to its denizens?
In this introductory adventure, you’ll learn the basic rules for Open Legend by playing through an adventure. One player will take the part of the game master and be responsible for directing the adventure and controlling the enemies, monsters, and non-player characters. The rest of the players will act as the player characters, each controlling a hero of legend who will accomplish great things.
