Keira Sage

Early Life
Sancha is the sister of Adam, Jax, Max and Mikhail Sage. Their parents remain something of a mystery; her father's whereabouts remain unknown, but her mother was killed by Inquisitor Seren Teancum Mordavo when Sancha was a child. Like her siblings, Sancha was raised without the benefit of Jedi teaching; unlike many of them, she never fully came into the fold. She raised and trained herself in the slums of Metellos, a street kid with bizarre powers, always on the run from the Inquisitors.

Jedi Career
Knowing that her parents had been Jedi, and that she had siblings somewhere, she paid attention to newsfeeds. Eventually she learned that she shared a last name with various Jedi, and found a way off Metellos. She met her brothers and joined the Jedi, but her street-kid independence and universal distrust soured her relationship with the Order. She gained something of a reputation for breaking rules, and when the third Death Star arrived at Coruscant, she was one of the Jedi who vanished into the undercity to help resist the Imperial invasion. Though most of the surviving Jedi eventually regrouped on Onderon, Sancha never did. She found too much satisfaction in hunting Imperials, and spent a year in the undercity, quite cheerfully playing with the Dark Side. Though the Jedi had taught her to improve and control her powers, she grew up as a pragmatic survivor.

Eventually it became necessary to hunt Imperial Darksiders - minions of Damascus and Kormoran - with their own techniques. She learned such powers as Force Lightning almost by osmosis (though the Imperial Forcer she questioned wouldn't have characterized her interrogation in such gentle terms.)

Extraction
Though she had eluded Imperials and Jedi alike during her time on Coruscant, eventually her brothers tracked her down and took her offworld. She joined them on various missions, fought at the Valley of the Jedi, and eventually wound up at the Jedi Temple on Ossus. Her outlook on the universe and the Force had not significantly changed.

Many Jedi consider her a threat; others call her a troubled child or a bloodthirsty vigilante. She does not get along well with her brothers, though she has spent some quality time with her Jedi-killer distant cousin, Lamech Sage.
