The Seven Dark Jedi referred to Jerec and his six Dark Jedi companions, who were intent on locating the Valley of the Jedi and exploiting it for their own dark purposes. All except Yun were killed by Kyle Katarn, who spared Yun's life after having defeated him in a lightsaber duel in the administrative tower of Barons Hed. Yun, however, would die a short time later by the hand of Sariss after saving Katarn's life.
Jerec, former Jedi Master, Inquisitor, and ruthless leader of the Seven Dark Jedi, was extremely powerful in the Force and posed one of the biggest threats to the galaxy since the death of Palpatine.
Jerec undertook to study the dark side in all its forms, reading from the Dark Side Compendium written by Darth Sidious himself. It was there that he gained the idea of forming a band of seven Dark Jedi melded to one will, a concept which would remain with him throughout his life.
Sariss, daughter of Lord Cronal and second-in-command to Jerec, she considered herself Jerec's primary apprentice, was a coldblooded killer and dangerous warrior who mastered most aspects of lightsaber combat.
Boc Aseca the Crude, personification of insanity and master of his own bizarre version of Jar'Kai dual blade lightsaber combat, was truly ruthless and enjoyed inflicting pain and suffering onto others.
Maw, a former Jedi Shadow turned into a dark side killing machine by Jerec, was embodied pure anger, rage, and hatred, and developed his own version of the dangerous type of Trispzest lightsaber combat.
Picaroon C. Boodle and Gorc were known as the Brothers of the Sith. Boodle's wits and tactical sense combined with Gorc's brutal strength made the two nearly invincible.
Yun was the youngest and least experienced of the Seven Dark Jedi. Eager to prove his worth to Sariss, whom he considered his mentor, Yun was a deadly foe in combat.
The Seven Dark Jedi, like Darth Krayt and Exar Kun, are some of the relatively few dark side characters in the Star Wars universe who do not limit themselves to red lightsabers. Though Jerec and Maw use red sabers, they are the exceptions: Yun wields a yellow saber (which Katarn took for his own when his first lightsaber was destroyed and Yun died), Gorc and Pic wield orange ones, Boc wields purple ones, and Sariss wields a blue one.
