Ordered by the Inquisitorius to infiltrate the Jedi Praxeum on Yavin 4, Brakiss became one of the first trainees of Luke Skywalker. Skywalker, who knew the reason why Brakiss was there, tried to turn him to the light numerous times. After three years at the Praxeum, Brakiss underwent an ordeal to face the darkness in his own soul, during which he saw the darkest parts of himself and fled, psychologically scarred by the incident.
Brakiss returned to Msst and reported in to his supervisors, but only under the condition that he live in peace from then on in. Deeming Brakiss of little use now that his mind was not whole, they agreed. Brakiss then left Msst again to find his own path. He then made his way to the droid foundries of Telti, to heal and recuperate.
But in 17 ABY, under the influence of another fallen Jedi of Skywalker's academy, Dolph, he fell fully to the dark side. Dolph, now known as Kueller, and Brakiss attempted to overthrow the New Republic in what was called "The New Rebellion", by manipulating political events and strategic use of powerful miniature bombs implanted in all the droid that came out of Telti, which Brakiss still controlled.
After that plan failed, Brakiss went to the Deep Core and reestablished his Imperial warlord contacts, becoming a neutral broker between the replacement warlords. In the wake of the Pellaeon-Gavrisom Treaty, which was met by disgust by Brakiss and the surviving Deep Core powers, all parties pooled their resources and created the Shadow Academy, a Dark Jedi academy which was to be led by Brakiss.
From his new hyperspace-capable space station equipped with a cloaking device, Brakiss headed to Dathomir and recruited Nightsister Tamith Kai, who became his second in command, and her apprentice Vilas (among others), and they used the Great Canyon Clan as a recruitment ground.
In 23 ABY, his agents led by Tamith Kai raided the GemDiver Station in the gas giant Yavin and kidnapped Jedi trainees Jacen Solo, Jaina Solo and Lowbacca. He and Tamith attempted to brainwash them though their captives resisted their attempts to indoctrinate them they were then rescued by Luke Skywalker and Tenel Ka
Realizing that capturing high-profile people and any existing Jedi trainees may bring unwanted attention, Brakiss's agents went on a recruitment drive in the dangerous lower levels of Coruscant, and were told to bring back people no one would miss. Among their recruits was Zekk - a friend of the Solo twins. Zekk, believing that no one cared for him, was fully brainwashed and became Brakiss's protégé and eventually, the Shadow Academy's Darkest Knight.
With the sudden arrival of the back-from-the-dead Emperor Palpatine, Brakiss then gathered his forces and attacked the Jedi Academy. He arranged a meeting with Skywalker, who again tried to turn him back to the light. Brakiss refused to listen to Skywalker, and returned to the Shadow Academy. When he arrived, he demanded to see the Emperor, but he discovered "the Great Leader of the Second Imperium" was really nothing more than four Royal Guards. Furious, he killed three of them, but the fourth escaped and activated the Academy's self-destruct system. Brakiss was killed in the ensuing explosion.
