The last scene of this ending shows the main characters, including Revan, being honored by the Republic at the site of the temple on Rakata Prime; a picture of later events has emerged from subsequent games and novels.
Also, at the ancient tomb of Ludo Kressh in Korriban, the Jedi Exile fights a silent vision of Darth Revan, in which they appear to wield two lightsabers, one red and one violet.
The two sides of Revan, one Jedi, the other Sith, then reunite, with the now-whole spirit warning the player and their allies that they must undo what has been done, lest otherwise the Emperor will see his evil plans through and everything will be lost.
In the third-season episode "Ghosts of Mortis," Revan would have appeared as a Sith Lord alongside Darth Bane as advisors to the Son, a dark side embodiment.
Stealing the ship the Ebon Hawk from the crime lord Davik Kang, Carth and his companions escape Taris just as Darth Malak orders an orbital bombardment on its surface.
Revan tasked Carth with protecting the Republic and left in search for the true Sith Empire in the Unknown Regions prior to the events of the game.
When the Sith Lord Darth Nihilus attacks Telos five years after the end of the Jedi Civil War, Carth leads the Republic fleet in defense of the planet and the space station orbiting above it.
Optional conversations with Mission will reveal details about her past and how she and Zaalbar met, and eventually unlocks a subplot side quest involving her brother Griff.
Towards the end of the game, if the player character embraces their identity as Darth Revan, Dark Lord of the Sith and sides with a fallen Bastila Shan, Mission and Zaalbar will attempt to defect from the party.
Bastila Shan, voiced by Jennifer Hale, is first mentioned as the commanding officer of the doomed Republic ship the Endar Spire, which has been boarded by Sith forces who are in pursuit of her.
She escapes the destruction of Taris with the player character's party by stealing a crime lord's ship, the Ebon Hawk, prior to an orbital bombardment by Malak's forces.
Bastila later confronts Revan atop an ancient temple on the Rakatan world of Lehon, where she gives the former Dark Lord of the Sith an ultimatum to join forces with her.
She is confronted again on the Star Forge, where she is defeated by Revan in a lightsaber duel; the player may choose either to kill her upon her request, or to spare her which leads to her projecting Battle Meditation in the Republic fleet's favor.
If the player chooses to return to the dark side, Revan and Bastila turn on and kill the remaining Jedi party companions on top of the Rakatan Temple on the Unknown World.
A year after the Star Forge's destruction, Revan, having remembered a great threat to the galaxy he discovered as leader of the Sith, sets out into the Unknown Regions, leaving most of his companions behind, including Bastila, who is at this point pregnant with their son, who she names Vaner in memory of his father.
Depending on which path the conversation is steered in by the player, Revan may either fight (and kill) her, or redeem her, where she joins the party to discover the location of the Star Forge and returns to the Order as a Jedi Knight.
Disappointed with the Jedi’s decision, Jolee left the Order and started wandering the galaxy before crash landing on Kashyyyk, where he lived for 20 years until he met Revan.
Kimberley Wallace of Game Informer included Jolee Bindo in her list of best BioWare characters; she called him a "cranky old man who hacks the hell out of enemies is hard to top".
Atton Rand, voiced by Nicky Katt, is a human pilot that the Jedi Exile meets on the asteroid mining station Peragus II.
When Kreia discovers Atton’s past when they are imprisoned by the Jedi historian Atris on the planet Telos, she uses the information to blackmail him into remaining with the Exile's party as pilot of The Ebon Hawk.
Should Atton turn to the dark side and have a low influence rating with a player character who is female, he will attack fellow party member Mical out of jealousy for her affections.
[16] Brianna, voiced by Grey DeLisle, is the "Last Handmaiden" on a Jedi Academy located on Telos IV in Star Wars: Knights of the Old Republic II: The Sith Lords.
GamePro's Hugh Sterbakov ranked Darth Malak as 22nd most diabolical videogame villain of all time, saying he was "one of, if not the coolest expanded universe Star Wars character yet".
The player's character Jedi Exile eventually defeats Sion several times, and convinces him to end his own miserable existence by letting go of the Force.
The character's distinctive mask is also made available as a loot item for Star Wars: The Old Republic if the Crime Lord's Cartel Pack DLC is installed.
[28] As the “face” of the marketing for The Sith Lords, the character has been featured prominently in promotional material and subject to merchandise, including several action figures.
[35] Chris Freiberg from Den of Geek ranked the introduction of Darth Nihilus as one of the most memorable moments in Star Wars video game history.
[36] Glixel listed him as one of twenty "awesome" Star Wars characters originating in video games, and considered him "terrifying" and "more of a malevolent ghost than a typical self-serving Sith".
[35] The Citizen's Lake Life editor David Wilcox opined that Darth Nihilus is the best designed character outside of the Star Wars saga's "main players".
Prior to the events of The Sith Lords, Atris had an idealistic view of the Jedi that bordered on fanaticism, believing that they were the perfect guardians of the galaxy and, as a result, did not tolerate any criticism directed towards them.
