As the tranquility established by the Treaty of Coruscant started to crumble around 3641 BBY, the Jedi Master and Republic Fleet Admiral Oteg received a communication from the spirit of the long-deceased Jedi Meetra Surik. Surik urgently requested Oteg to liberate a crucial Jedi prisoner from within the Maelstrom nebula, as this prisoner held critical information about the Sith Emperor himself. Consequently, Oteg assembled a specialized team composed of troopers, Jedi, and other individuals allied with the Republic, with the intention to assault the Imperial fortress located on the planet Taral V. Their objective was to retrieve a computer created by the Gree species, which would enable the Republic fleet to successfully navigate the treacherous Maelstrom.
Following the Sith Lord Darth Angral's campaign of vengeance directed at the Galactic Republic, alongside other secondary conflicts, the fragile peace resulting from the Treaty of Coruscant began to break down. Both the Republic and the Sith Empire started to prepare for impending warfare. During this period, Oteg, a Jedi Master and former member of the Jedi Council who also held the rank of Fleet Admiral within the Republic Navy, was visited by the Force ghost of Meetra Surik. Surik had met her death more than three centuries prior during a failed attack aimed at the Sith Emperor, and since then, she had been supporting her ally Revan as the Emperor drained Revan's strength and knowledge.
Surik shared her knowledge of Revan's difficult situation with Oteg, and she requested that the Jedi Master extract him from his confinement within the unnavigable Maelstrom nebula. Surik instructed Oteg to acquire a computer used for astrogation on Taral V to reach the prison—a computer that was designed by the enigmatic Gree species. As a result, Oteg put together an elite strike team consisting of Jedi, Republic troopers, and other individuals aligned with the Republic, with the purpose of obtaining the computer.
The strike team utilized a stolen Imperial shuttle to land on Taral V, positioning themselves near the main Imperial fortress. Subsequently, they advanced towards the fortress's security outpost, engaging in combat with the various Imperial soldiers, jurgorans, gundarks, and Imperial commandos that blocked their path. Gattan, along with his pet vine cats, were killed during this process, and the strike team's attack on the security outpost resulted in the destruction of several Imperial war droids and the elimination of more than a dozen defenders. Captain [Shivanek]'s ultimately futile resistance and demise enraged his jurgoran pet, Ripper, which forced the strike team to eliminate the large creature before they could deactivate the fortress's external defenses. Following this, they continued further along the path and crossed the bridge that led to the main fortress.
Once inside the fortress, the strike team engaged a number of Imperial troops and additional jungle animals. After crossing a heavily defended bridge, they entered the main section of the fortress. After defeating Doctor Zharen and Lord Hasper, they battled a powerful war droid located at the entrance to the internal corridors. The strike team then encountered Kilran via a hologram. The Imperial Moff announced his intention to bombard the fortress from orbit, but the strike team pressed on with their mission despite this threat.
The strike team fought their way through more Imperial soldiers and Sith Warriors until they reached the center of the fortress, where they confronted General [Edikar] and a group of turrets. After the general was defeated, the team confronted an Imperial researcher who possessed the Gree computer. The computer was handed over, but only after the strike team agreed to allow Imperial forces mapping the Maelstrom to evacuate. Ultimately, Imperial Grand Moff Rycus Kilran bombarded and destroyed the base from orbit in a failed attempt to prevent the Republic strike team from escaping with the Gree technology.
The Republic Navy subsequently used the Gree navigation computer to attack the Imperial prison located within the Maelstrom Nebula and successfully rescue the Jedi Revan.
