Star Wars
The Sith are a group of beings who use the force as a power source; they are trained to use the force to gain ultimate power. The Sith normally use the force to gain power in battles with their enemy who are the Jedi. They also use the force to bring destruction to the universe and anything in their way. They are the antagonists, and they usually use red lightsabers in contrast to the variety of colors used by the Jedi. There are usually only two Sith, a master and an apprentice.
