The Dawn of Defiance campaign is set during the period between Star Wars: Episode III Revenge of the Sith and Star Wars: Episode IV A New Hope. The exact dates are left vague so that Gamemasters can choose to run the adventure at any specific timeline they prefer within those dates. However, the campaign makes the basic assumption that the first adventure, The Traitor's Gambit, begins just a few months after the end of the Clone Wars.
