Eden Exillus

Eden Exillus was a Force-sensitive Human male Sith Lord that stood beside the Dark Lord, serving the Order as the single embodiment of the Dark Council.

Early Life
Eden Exillus was born as the youngest of three sons to Elena Exillus (née Sipherius) and Ryon Exillus on Dromund Kaas in the Imperial Palace.

Though it wasn't a peaceful birth, as moments prior his birth, the Jedi had sent a strike team to infiltrate the palace after obtaining information from the treacherous maester who overlooked the education of the sons, to ultimately assassinate the family as Elena was going into labor.

With Ryon absent in the palace, Elena was left to defend her children alone, though into labor amidst the battle, she was unable to fully protect herself from harm but was ultimately saved by Ryon who appeared and fended off the attackers, Though he couldn't prevent the Republic forces and the maester from taking away their eldest son.

Ultimately, Elena was unable to survive Eden's birth and died in Ryon's arms, with Eden on her lap.

Eden and his older brother Lucien were raised for the following years by their father, until eventually a Sith civil arose and challenged the Emperor, and led him to his demise, though he took precautions and ensured that his children would be able to escape Dromund Kaas, which led the children to travel to Korriban and eventually be found by Geziel Haden, a rogue Sith Lord, who abducted them and brought them into their ship.

Geziel, seeing family bonds as a weakness, forced them to choose which one of them would die, and eventually killed Lucien in front of Eden, leaving him with his corpse. Not long after, Geziel dropped Eden off at Eshan, instructing him to grow up as Sith and leaving him to live with the Echani. The death of his family left emotional scars in Eden, and led him to join a monastery on Eshan.

Rise as Sith
The emotional damage that had been done to him had sticked to him and was one of the reasons why he had an unquellable hatred for both Geziel and the Jedi, which eventually led him to start massacring the other monks in the monastery, which led to Geziel's attraction and sooner than later, he appeared. After a brief battle, it was clear to Eden that Geziel was still levels above his own, and he came with to join the Sith to acquire the power to end Geziel once and for all.

Eventually, he was sent to Tatooine, where he came across the Hutt Cartel and allowed himself to be captured, but after a while decided to massacre the group in a strong rage. Afterwards, he was approached by Egan Dysal, the new Dark Lord of the Sith, who offered him a seat in his council which Eden saw as an opportunity to gather power to kill Geziel. Eden settled on Korriban, where he started to act as it's ruler in name of the Dark Council.

The fall of the Sith
The Empire under Egan didn't last long, as he was eventually assassinated by a man named Shamen. After realising Egan's failure, Eden disbanded the Sith Empire and set out to Ziost, to confront Geziel one more time. After a brief chat, Shamen appeared and the two started to fight. Eventually, Eden lost and was murdered in the Demi Keep.
