Nisha "Tiamat" Kenvon is an officer with the 9th Nihilgenia that experienced a traumatic empowerment by a ritual of Muz Ashen that left her with the powers of a Grand Master and the belief that she is the reborn Krath Sorceress Tiamat.
Brief History
Nisha "Tiamat" Kenvon Born in hyperspace to a Sephi father and a Kiffar mother, Nisha has no real homeworld to speak of. Her parents eventually settled on Kyataru, where Nisha was educated and eventually joined with the Nihilgenia as an officer.
Captured at Amahara by Claudius Tang'va and aggressively interrogated for intel about the ruling Keibatsu family, Nisha's academic studies of the Jedi and the Force found practical application. Eventually released, her experience with the enemy of the Throne made her invaluable to the Nihilgenia, helping the Nihilgenia understand the motives and acts of the self-professed Jedi leading the Suukou Bodai.
Eventually reassigned to the 9th Nihilgenia as a specialist, Nisha helped Muz Ashen seek out artefacts of the ancient Jedi, Sith and Krath alike. After a grueling hint for a dagger held by an enemy of the Dark Brotherhood, Nisha volunteered to have an ancient rite performed on her that was intended to drastically alter a person's Force Sensitivity.
Interrupted by Kojiro Keibatsu, acting on orders from the Iron Throne, the ritual spun out of control, tearing the patterns of both herself and Kojiro and leaving them both force sensitive. The massive influx of power twisted them both in violent ways, Kojiro's body battered and broken, Nisha's mind splintered. Turning violent against the Keibatsu and calling herself "Tiamat", it took a brutal fight to bring her down, her body marked with force tattoos to keep her madness at bay.
Flush with newfound power, Nisha became an apprentice of Muz Ashen, learning to control her newfound abilities.
Demeanor
The Rite on Stheno Nisha is prideful and prejudiced against non Force Sensitives (with the notable exception of Blackwind and the Nihilgenia), viewing them all somewhat sociopathically as tools and replaceable ones at that. She harbors a deep resentment for the Jedi, and to a lesser extent, the Sith and what has become of the Krath orders, viewing their current state as weak and supplicants to the domineering Sith of the Brotherhood.
Nisha styles herself as the ancient Sorceress Tiamat, refusing to answer to her birth name. She believes that the wild conduit opened and damaged by the interrupted rite on the planet Stheno called the tormented ghost of the Sorceress to the place, and allowed her to be reborn into her body.
Abilities
Prefering to use mental manipulation, seduction and Illusions to sway things to her own ends, Nisha is a fearsome puppetmaster and seer. As an Arcanist, she is driven to unearth the ancient secrets of the Force, and constantly seeks out more knowledge.
Granted an obscene amount of power without the appropriate time to learn how to control it, Nisha often responds with overwhelming force to any threat. Her skill with lightsabers is impressive, having trained under Muz Ashen in the art of Jar'Kai and becoming a master of the form herself.
Nisha's grasp of ancient Lore is impressive and integral to her goals, having a wealth of information about rites, artifacts and practices of almost any group tied to the Force. From the Order Aspectu and the Whills to the Nightsisters and the Krath, Nisha is an expert, which lends credence to her claims that she is the reborn Sorceress Tiamat, a claim she aggressively defends.
