The Star Forge was a massive orbital factory built by the Rakata of the Infinite Empire. The station drew its power from the Dark Side of the Force, a unique blend of Force power and machinery. Darth Revan discovered the Forge while on Dantooine, where there was a Star Map, a partial map of the location of the Star Forge. When Revan and Darth Malak collected all the Maps, they took over the Forge and restarted it, using it to churn out droids and ships for the Sith. However, Revan was injured severely and captured in a battle with several Jedi, and Malak took the forge over, continuing his campaign against the Republic.
The redeemed Revan was later responsible for the destruction of this artifact of the Dark Side.
