The Battle for Rakata Prime
The Battle of Rakata Prime was a massive space batte between the forces of the Galactic Republic and the Sith Empire. It took place above the planet Lehon, more commonly known as Rakata Prime.
The battle began looking like a sure loss for the Repubic, as the Jedi Bastila Shan was using her battle meditation against the Republic fleet, but the tide turned when the redeemed Revan convinced her to return to the light side, and she used her meditation in favor of the Republic. The battle ended in the ultimate destruction of the Star Forge and the death of Darth Malak.
