In mythology, the hero's journey begins with the "call to adventure." Destiny's herald is usually someone or something fairly ordinary--a frog, a deer in the forest, or in this case a humble droid--that carries an important message for the one who is prepared to receive it.

As the Star Wars story begins, a battle in space rages between the evil powers of darkness (the Galactic Empire) and the forces of good (the Rebel Alliance). Princess Leia sends a plea for help to Jedi Knight Obi-Wan (Ben) Kenobi on the planet of Tatooine. The hand of Fate, in the form of Jawa traders, brings her message to Luke Skywalker, a young farmboy. When Luke sees the message hologram, he is drawn into a quest to rescue the Princess and ultimately to save the galaxy.
