Star Wars is a series of movies, books, games, and TV shows about a group of characters who battle against each other in outer space. The two groups of characters are called the Rebels and the Empire. The Rebels are made up of good people, like Luke Skywalker, who fight against the evil Empire, which is led by the powerful Darth Vader. The story usually involves lightsabers, which are special swords that glow and make noise when they clash. There are also robots, aliens, and huge spaceships. The Star Wars movies usually have exciting battles between the Rebels and the Empire, and there's usually a happy ending when the good guys win.
