Bane, as he had been christened, quickly became one of the best students at the Academy before he lost his faith in the dark side of the Force.
Though Bane was able to regain his confidence in the dark side, he lost
his trust in the Brotherhood of Darkness, believing it to be a flawed
organization whose leader, Kaan, was a coward and a fool. Deserting the order, Bane studied the holocron of DarthRevan, and, armed with new knowledge, helped destroy the Brotherhood, allowing him to create his own Sith Order.
He then instituted a Rule of Two, which stated that there could be only
two Sith to avoid the infighting that had plagued the Sith for
millennia. He also took both the title of Darth and an apprentice named Darth Zannah.
A decade later,
Bane began to worry that his apprentice was too weak to overthrow him
and assume the mantle of Dark Lord of the Sith, as was necessary under
the Rule of Two. He began to research the secrets to prolonging his
life by transferring his essence to another body, and traveled to Prakith, where he claimed the holocron of the ancient Darth Andeddu. After returning from Prakith, Bane was ambushed by a team of assassins hired by Caleb's daughter, Serra, and was captured. Taken to Doan, Bane was imprisoned and interrogated, only to covertly gain his freedom soon afterward. Encountering Zannah on Doan, Bane dueled
his apprentice, who sought to become the new Dark Lord. The fight ended
in a draw, with Bane escaping and heading to Ambria with Darth Cognus, an Iktotchi
assassin skilled in use of the dark side who Bane planned to take as
his apprentice if Zannah proved herself weak and unworthy. There, Bane
and Zannah engaged in a fateful duel that resulted in the death of the Sith'ari and Zannah claiming the title of Dark Lord. Nearly a millennium later, Bane's Sith Order defeated the Jedi Order and overthrew the Republic.
Darth Andeddu, also referred to as the Immortal God-King of Prakith, was an ancient humanoidmale who reigned as Dark Lord of the Sith, and was dubiously thought of as the forebear of the "Darth" title. A paranoid man, Andeddu believed that his subordinate Sith Lords—whom
he regarded as his enemies—wanted to claim his vast collection of Sith
lore and ritual for themselves. He was eventually betrayed and
overthrown by his followers, forcing him to flee the planetKorriban for the Deep Core. Andeddu made the world of Prakith his domain where he ruled for centuries as a deity until his physical demise,
at which time he entombed himself in an attempt to deprive his pursuers
of the power they sought to steal. Prior to his physical death, Andeddu
stored all of his wisdom within a holocron which also contained his most arcane secret: the ability to cheat death by transferring one's essence into another vessel. A Sith cult founded by Lord Andeddu called the "Malevolence" constructed a temple in reverence of their Dark Lord, and guarded the fortress for generations in anticipation of the God-King's return.
The legend of Darth Andeddu and his incredible powers remained at large long after his death, and the Jedi Order
even attempted to erase all knowledge and reference of the Dark Lord
from galactic record. Despite their best efforts, whispers of Andeddu's
existence still remained prevalent. His holocron survived as well—first uncovered by the Sith Lord Darth Bane on Prakith in 980 BBY, then rediscovered by Darth Tyranus on Korriban in 21 BBY, and later recovered by Darth Krayt and his One Sith Order more than a century later. Krayt, who suffered from a Yuuzhan Vongslave seed infestation that threatened to leave him bereft of sentience, allowed his lieutenantDarth Wyyrlok III to access Andeddu's holocron in search of possible solutions. The device led the Chagrian Sith on a journey to Andeddu's Keep on Prakith, where he encountered and defeated the Malevolence cultists, but in doing so, he revived
the ancient body of Darth Andeddu. The Dark Lord then dueled Wyyrlok on
a battlefield of the mind, a contest which ultimately resulted in
Andeddu's demise. His corpse was resealed within the tomb that had
housed it for countless millennia, and his collection of Sith doctrines
was pillaged by Wyyrlok, who hoped to obtain a viable means of ending
Darth Krayt's plight.
