Unbeknownst to the Jedi Council, Revan and Malak were corrupted by the Sith Emperor. The Jedi thought the two had fallen to the Dark Side on their own.
However, Revan and Malak eventually found their way to Dromund Kaas and discovered that the Sith Empire indeed still lived. Their attempt to eliminate the Sith Emperor went horribly wrong, with the Emperor dominating their minds and finally turning them to the dark side.
Who was Darth Revan's apprentice before he was turned to the light side?
Darth Malak, voiced by Rafael Ferrer, is the old Sith apprentice of Revan and the main antagonist of the first game. As Jedi, Malak and Revan disobeyed the Jedi Council and helped the Republic defend against the Mandalorians.
Convinced that his Master had died, Malak usurped Revan's mantle of Dark Lord and ruled the Empire unchallenged, brutally conquering territory after territory and taking the fallen Jedi Darth Bandon as his Shadow Hand. It was not long until Malak was proven wrong about his beliefs regarding Revan's death.
By force - SWTOR's Reason - Revan and Malak were overconfident and faced the Emperor alone. They were turned to the Dark Side by Force to claim the Star Forge for Vitiate. Later, they betrayed Vitiate and used it for themselves.
Revan located the Star Forge and found that Malak had made Bastila his new apprentice, but Revan's love convinced her to return to the light side. Revan defeated his former apprentice in battle and saved the Republic from the Sith, now hailed as a hero once again and welcomed back into the Jedi Order.
However, the torture that he experienced at the hands of the Emperor had splintered Revan's mind, and while part of him attempted to become one with the Force, the rest rejected death and clung to life, embracing the dark side.
The Duel on Darth Revan's Flagship was a confrontation during the Jedi Civil War between the Dark Lord of the Sith Revan, and Sith apprentice Darth Malak. It took place in Revan's flagship. The lightsaber duel resulted in Malak's defeat and the loss of his jaw.
They were originally led by Darth Maul (who claimed to be the one chosen to seek out Revan's descendant) until he "stepped down" when he took Ezra (who was revealed to be Darth Revan's descendant) as his apprentice and appointed him Mandalore and the offical leader of the Revanchists under the name Keneh Heru (when in ...
"Revan had many Masters, Zhar, Dorak, Master Kae before Kae left for the Wars. Toward the end of his training, he sought out many to learn techniques. It is said that he returned to his first Master at the end of his training, in order to learn how he might best leave the Order."
After being rejected and forced to flee to the Star Forge, Bastila confronted Revan again and lost. She begged him to kill her, but he refused and used the power of their love to bring her back to the light and help the Republic in the Battle of Rakata Prime. She later married Revan and soon had a child called Vaner.
What we already know (if you've played Knights of the Old Republic): Revan was a Jedi who fought in the Mandalorian Wars. Then, he turned to the Dark Side, and led the Sith empire against the Republic in the Jedi Civil War.
Darth Malak : Savior, conqueror, hero, villian. You are all of these things, Revan... and yet you are nothing. In the end, you belong to neither the light nor the darkness. You will forever stand alone.
This mask was originally worn as a part of a Mandalorian female's armor, and had a red and gray color. Ten years after her death during the Mandalorians' genocide of the Cathar people on their homeworld in 3973 BBY, the mask was claimed by the Jedi Knight Revan and was immediately donned by the Jedi.
The mask belonged to a Mandalorian woman on Cathar during the Mandalorian Wars. She took part in the Battle of Cathar under Cassus Fett. The woman knew that Fett was going to commit genocide on the Cathar people and tried to convince Fett to spare them.
In Legends, Revan was a Jedi Knight who broke away from the Jedi Order, became a Dark Lord of the Sith, and formed a Sith Empire that waged war against the Order and the Galactic Republic.
Disney used Revan as an inspiration to create Kylo. His armor, inner conflict between Light and Dark and his use of the Force. Snoke considers Kylo to be the ideal embodiment of the Light and Dark sides of the Force, much like Revan, who was a master at both sides of the Force.
Her knowledge of the fact that Anakin Skywalker and Darth Vader are one and the same naturally raised some big questions about her character, especially since his identity was supposed to be a secret. In Obi-Wan Kenobi episode 5, what she knew about Anakin turned into a major plot point.
