Chapter 6. Force Essence
For the next 10 years Cognus hunted Darth Millenial and the Brotherhood remnant. Then in the tenth year she had a vision of the Brotherhood dying at the hands of a human female who followed the teachings of Darth Bane. So she decided to let it go, the hunting of Darth Millenial and the brotherhood. While on the planet Umbara she received a vision of the young man who would become her next apprentice.
She searched for many years utilizing her agents to the point of obsession. Darth Cognus grew older and older until she was forced to travel to her home world to find a new body to house her mnd and essence. She found a young Iktotchi female who possessed the ability to touch the force. Using Sith Sorcery Cognus prevented the young Iktotchi from foreseeing the doom of her parents and the plan she had for her.
The death of De'Mella's parents was deemed an accident, but it was Darth Cognus who caused the accident. After the death rights were performed Cognus ingratiated herself to the young female. After three years Cognus performed the ritual of force essence transfer. After successfully taking over the girl's body Darth Cognus began once again to focus on her shadow empire and the seeds laid down by Darth Bane and Darth Zannah.
With a fresh young body Cognus was able to travel to Corsucant and through her power controlled several dozen Senators. Three of whom she ruined the careers of. It was during this time that Cognus constructed her own Sith holocron in her fotress in the industrial sector of Coruscant. A fortress that would one day become home to Darth Sidious.
After three years on Coruscant Cognus left to travel to the unknown world and place her holocron in the archives. It was during this time that Darth Millenial founded the Prophets of the Dark Side on Dromund Kaas. He built a magnificent edifice and a sophisticated archive. Despite all his accomplishments he could not join the brotherhood remnant as he had failed to kill his master. Neither could he challenge his former Master as she was more powerful than before. Darth Cognus had ruled the Sith for the past 219 years.
