From the introduction:
Tales of Xadia: The Dragon Prince is a tabletop roleplaying
game about people who experience love, war, family, heartbreak, and triumph in the world of Wonderstorm’s The Dragon Prince. With your friends, you create characters using familiar archetypes from the show. In your shared imagination, you forge alliances, uncover secrets, engage in mighty battles, and protect those you love from peril and prophecy. Work together or at cross-purposes... or both! Whatever your chosen path, your characters explore the mysteries of the elves, the human kingdoms, and the dragons, as well as the primal sources that flow through everything.
Tales of Xadia uses the Cortex game system. This rules primer introduces you to key elements of Cortex as it appears in this game, from bringing life to characters of your own creation to spinning tales of wonder and magic.
