Darth Revan is the most powerful Sith Lord to ever grace the galaxy. He was a Jedi, but abandoned the Order to join the Mandalorian wars in 4006 BBY (BEFORE BATTLE OF YAVIN). He then fell to the Dark side and harnessed the power of the ancient space station built by the Rakatan Empire in 20,006 BBY: The Star Forge. His apprentice, Darth Malak, was also a fallen Jedi who followed Revan into the war. Malak betrayed Revan from afar when his masters ship was boarded by a Jedi strike team in the Bpffash system. Revan then returned and exacted his revenge on his former apprentice. Revan then left republic space, leaving the Sith Empire and the Star Forge in the hands of his new apprentice: the fallen JediBastila Shan. Bastila, although powerful, was not strong enough to withstand the corruptive power of the Star Forge, and many of the Sith refused to follow one so young and inexperienced. The Sith Empire collapsed into cicil war in Revan's absence, and he disappeared in the Outer Rim. No one know where Revan roams now. REVAN LIVES!
The Force is a field of power that is meant to serve those who are worthy. The Jedi treat the Force as a burden. They refuse to accept its true nature.
The following allows those who believe in true power to glimpse the true nature of the Force:
Peace is a lie. There is only passion.
Through passion, I gain strength.
Through strength, I gain power.
Through power, I gain vitory.
Through victory, ny chains are broken.
The Force shall free me.
The Mandalorians are an extinct group of warriors who believe that true honour comes from the glory of battle. There were many lans of Mandalorians, and one of the most famous was Ordo. The leader of the Mandalorians took the name Mandalore, and when he died, another took his place. The Mandalorins became officially etinct 6 years after the Battle of Yavin when Bobba Fett, the last of the Mandalorians, was eaten by a Sarlaak in the Dune Seas of Tatooine.
