Oden Malksch was a male Human who achieved the rank of Jedi Knight within the Jedi Order. He served during the decline of the Galactic Republic, prior to the rise of the Empire and the subsequent dismantling of the Jedi, as described in legends.
Having been instructed in the Force by the Jedi Order, the Force-sensitive Oden Malksch successfully completed his Trials of Knighthood, thereby attaining the rank of Jedi Knight. Malksch followed the path of the Jedi Consular, specializing as a Lore Keeper and earning recognition as a respected historian within the Order. Jedi Malksch was stationed at the experimental academy located on Almas, where he authored several scholarly works concerning events transpiring in the Cularin System. Malksch took particular interest in the significant shifts within the Metatheran Cartel, Almas' governing body, as well as the increasing darkness emanating from an ancient Sith fortress, which appeared to be gradually accumulating power. Malksch's intention was that his writings would offer future historians insight into the era in which he lived, enabling them to comprehend the historical trajectory that unfolded.
Around the year 20 BBY, Malksch received the appointment of head archivist at the Academy. During his time in this role, seven corpses were discovered at the Sith fortress and subsequently brought to the Academy for examination. Among these bodies were two Jedi from the academy itself, along with the Dark Jedi known as Karae Nalvas. After conducting a comprehensive investigation, Malksch determined that their Force essences had been forcibly removed from their physical forms and were being held elsewhere. Malksch deduced that the orange jewel pendants adorning the necks of the bodies were somehow related to their unusual state. Consequently, Malksch shattered the pendant around Nalvas' neck, resulting in the transfer of Nalvas' essence into his own body. Now conscious within the form of the Dark Jedi Nalvas, Jedi Malksch gained the ability to sense the location where Nalvas' original essence was confined, along with the body's inherent desire to reunite with it. Leading a Jedi rescue party to this location, the Jedi were able to locate the trapped Force essences of the seven individuals, restoring all of them to their original states.
