Star Wars: The Fringe
Destiny is a mechanic which was first developed in Star Wars: Saga Edition. This is where the character has a Destiny which his life will present and has a huge goal to accomplish, although the character may not know it.
For example, Darth Vader’s Destiny was to bring balance to the Force. In order to do that, there had to be one Jedi, Luke, and one Sith, Darth Vader, for there to be balance. While Luke’s was to destroy the Emperor’s reign over the galaxy, and crush his oppressive society and bureaucracy. Luke did not know this until Star Wars: The Empire Strikes Back.
