Battle of Telos IV The Battle of Telos IV was a battle that started the downfall of the dark trinity of Darth Nihilus , Darth Sion , and Darth Traya in 3951 BBY . Prelude . The conflict was orchestrated by Kreia , who realized that Darth Nihilus had to be stopped from consuming all the life in the galaxy in his hunger for the Force . Knowing that General Vaklu and Colonel Tobin were allied with Nihilus , she lied to the latter — who had barely survived the Second Battle of Onderon — about a number of Jedi hiding in Atris ' s secret academy on Telos IV . In fact , the only Jedi inhabitant of the academy was Atris herself . The battle . Battle on the Station . Kreia ' s plan worked as intended . Immediately after leaving Onderon , Tobin reported the misinformation to Nihilus . The Sith Lord took the bait and moved his fleet to Telos IV to feed on the supposed Academy ' s Jedi . Despite the surprise of the Sith ' s appearance out of seemingly nowhere , the Telos Security Force , led by Lieutenant Dol Grenn , managed to keep them from completely overrunning Citadel Station until reinforcements arrived . Thanks to Meetra Surik ' s earlier aid in stopping a weapons smuggling ring , Grenn was able to arm some of his men with the confiscated weapons . The first reinforcements were sent from Dantooine and Onderon , led by Captain Zherron of the Khoonda Militia and Major Riiken of the Onderonian military , respectively ; both worlds , in the midst of political turmoil , had been stabilized by Surik during her search for the Lost Jedi . After that , Surik herself arrived on the station with the " Ebon Hawk " , accompanied by Mandalore the Preserver and his clans . With Surik ' s help , the combined Republic forces cleared Citadel Station of Sith troops and saved the fueling station . The Republic Arrives . Following the arrival of a large Republic fleet under the command of Admirals Carth Onasi and Cede , Surik prepared to infiltrate the Sith Fleet ' s flagship , the " Ravager " , with the help of Visas Marr , as well as Mandalore and his troops . Mandalore had his personal reasons to participate in the battle — he wanted to restore the Mandalorians ' to their former glory and remind the galaxy of their courage during the Battle of Malachor V . The Republic forces were too far away to cause any damage to the " Ravager " . Destruction of the " Ravager " . Meetra Surik , Visas Marr , Mandalore and the Mandalorians boarded the " Ravager " using a small shuttle and planted four proton charges at different sites of the ship . Unfortunately , one of the charges detonated prematurely when a squad was ambushed . Three cores on their own couldn ' t destroy the ship , so Surik got another one from the ship ' s missile bay . Surik , Marr and Mandalore confronted and killed Nihilus on the bridge , after which the group left the " Ravager " just before it exploded . With their flagship destroyed and their leader dead , the Sith were forced to retreat while the other Sith ships were destroyed by the Republic . Aftermath . In the wake of the battle Admiral Onasi requested an audience with Surik where he asked Surik if she had heard anything from one of their common acquaintance . Surik told Onasi that she hadn ' t heard or seen Revan , and was surprised that Onasi knew him . Onasi told Surik the story of his adventures with Revan during the Jedi Civil War , starting with their escape from the " Endar Spire " . He asked Surik to search for Revan , and asked her to tell Revan , if Surik ever found him , that Admiral Onasi was following Revan ' s orders to protect the Republic . Bastila Shan , who somehow escaped the Jedi purge that followed the Jedi Civil War , came with Onasi to the battle . She did not reveal herself to Surik though , and spoke only to Onasi after Surik left about what the Exile had told Admiral Onasi about Revan . Then , Surik took the " Ebon Hawk " off Telos , heading to the forgotten world of Malachor V to confront Kreia , to destroy the wound in the Force once and for all , and also to begin her search for Revan . Behind the scenes . The ending described above only occurs if the player indicates early in the game that Revan is male . If Revan is considered female , Bastila does not appear , and Carth asks the Exile to tell Revan that he still loves her . Carth does not appear at all if the player sets Revan to be dark sided , instead being replaced by Cede , and the cutscene where the Exile meets Carth is removed entirely . Also , Azkul and a group of his mercenaries appear in place of Zherron and the Khoonda Militia , if the Jedi Exile makes the dark side choice on Dantooine to help him . Also , the Onderon Royalist soldiers are replaced by Vaklu soldiers , if the Exile makes the dark side choice on Onderon by assisting Vaklu , Captain Riiken won ' t even appear too . The duel with Darth Nihilus was originally supposed to be much bigger and more threatening . In other material cut from the game , Citadel Station would be destroyed by the " Ravager " , crashing into it at some point during the battle . Also in a cut content , the Exile would encounter Jana Lorso , who lost all of her bodyguards and hired mercenaries . Jana would then panic and flee at the sight of Sith Troops and would be killed by a Sith turret .
