Darth Malicant

Dark Lord
Darth Malicant was a tremendously powerful sith lord who had amassed a small empire and caused devastation during his reign using his unique force abilities.

Abilities
Darth Malicant had many unique force abilities, these incleded force enthrall and force vail which could hide a force presence from a force sensitive and in more exercised states, use the force to conduct elaborate visual illusions and turn entire regions of space invisible. Both of these techniques were invaluable in his rise as he was able to remain hidden so deeply and also control the minds of those he was able to infiltrate the minds of. Darth Malicant also gained the memories and knowledge of those he enthralled and therefore gained incredible insight on enemy tactics forcing his enemies to constantly evolve techniques with every minor loss, when he enthralled force sensitives he could exploit the dark side within them to use the individuals force abilities on a sort of auto pilot function similarly to how Darth Shade while under Darth Malicants influence used his own unique force ability of force shade.

Malicants Soul Empire
Darth Malicants Empire was composed of enthralled beings of many different levels proving the incredible control Malicant had over his abilities. Using force Enthrall he was able to enthrall billions of beings, some of which would act as mindless zombies for infantry, others as fighter pilots, military strategist and fleet commanders, and others had only a subtle amount of enthrallment done to implant the fear of consequence to rebelling his will. This lesser level was the careful implantation of an idea which that grasped the victims mindset angling in Malicants favor. While Darth Malicant and his Soul Empire was never powerful enough to construct a Death Star like super weapon they did coagulate on Soul Trap, a large station and Super carrier holding thousands upon thousands of fighters which would swarm planets or engulf entire fleets.

Apprentice
Darth Malicant used his force abilities to convince the republic that Riekus had been killed on his mission to assasinate him, even vailing his presence in the force so that his close friend Vincus could not discover him and was too convinced he must be dead.

Malicant went on to implant the idea of abandonment into Riekus mind which tortured him with both the emotion itself and the guilt he felt in harboring it which Malicant used as a means to fuel rage against the Republic deepening Malicants grasp on Riekus' mind. Eventually Malicant was able to control Riekus and his tremendous force abilities.
