Age: 23 equivalent?
Personality: Doing things. Getting things done. as long as it allows Kachku to utilize her abilities, she likes doing it. most of the time it involves her master sending her to investigate tombs, or track down cowards, but every so often, she'll have to shock the answer out of someone. She has a hard time tolerating anyone that has not proven themselves not stupid, and is quick to let them know the fact, unless they happen to be in a position of power she cannot match, which generally descends into either her deriding their efforts as they prove themselves stupid, or holding her words until such time as she finds a weakness.
Motivation: Power, more and more. Legions of soldiers in a Grand Inquisition of the Galaxy.
History: Born into slavery to the Sith empire, Kachku's first rational thought was of how much she HATED her masters. She seethed with it through her formative years, keeping it to herself, but there were moments that it would slip through, and she would find herself unable to stop the font of hatred that spilled forth. While this eventually was tempered and attributed to the sarcastic contempt she holds for everyone around her, it also brought her beatings for impertinence.
The day after she would be fully realized as an adult of her people, one handler stepped a bit too far, and her rage spilled forth in cutting, angry, loud insults of everything from his parentage to his contributions to the local red light district. The beating she recieved was the worst she'd had as the officer she had insulted lashed out in his own rage. At the last, she pushed past a mental block and with no idea what she was doing, she lashed out with thick streamers of electricity, flaying the man alive right in front of her. The other officers had surrounded her, weapons ready, but as luck would have it, a Sith Lord had been present for her little display and stopped them. Intrigued by the sheer malice and cruelty displayed as the man had been melted into an unrecognizable pile of slag, she took the young Rattataki and tossed her into the harsh trials on Korriban.
A month later, Kachku killed her overseer, murdered the last candidate other than herself, and presented herself to Lord Zash as her apprentice. Thus began Kachku's service under the Empire.
