Darth Sehtra

Darth Sehtra was a ' ' ' of the ' during the ' and '. A talented sorceress, Sehtra found her body decaying rapidly by the time she became a Darth, prompting her to look into methods of extending her life, prefereably indefinitely.

She stumbled across old stories concerning Sith who'd supposedly  as a means of surviving forever, encouraging Sehtra to try and discover the process for herself.

Eventually, she did create her own variation of the ability, however it was far more destructive on the target body than she'd expected. When she happened across a Republic soldier on  and attempted to take her body, the dark power severely degraded the soldier's body.

Short on time and certain that the body of a Force-sensitive would last longer, she attempted to convince one of her apprentice's to willingly submit to the process, promising them eternal glory and claiming that their spirits and power would be fused- though this was a lie.

Galen Andriche fled when the invitation was put to him, attempting to escape his master by taking both himself and his girlfriend to Republic space. He was contacted beforehand, though, by Benjamin Lambert, who asked him to contact Sehtra and claim he'd changed his mind, allowing Lambert and his team to find and destroy her before she could switch bodies again.

By this time, Sehtra had joined the ' to choose a potential new host from the Revanites gathered on '. A willing target would make the transition easier, and so when Galen contacted her she gave him her location, unaware that she was being tricked into a confrontation.

When those hunting her finally arrived, Sehtra was eventually overpowered. Desperate, she used her immense power to ', teleporting to the ' on .

Unfortunately for Sehtra, this left her body almost completely sapped of vitality, and in her sudden flight from Yavin IV one of her pursuers had caught a glimpse of her destination through the Force.

While recovering in the Dark Temple, the Dark Lord was tracked down and confronted by a member of the team that had cornered her on Yavin IV, a  named Avexiss and the younger sister of the woman whose face Sehtra was wearing. After a brief exchange, the Jedi moved in for the killing blow, forcing a weakened Sehtra to attempt to take her body just before the blade hit.

Unbeknownst to Darth Sehtra, Avexiss had faced a similar mental invasion several years earlier, one that'd been partially successful. Along with her own not-insubstantial mental resistance the Jedi's mind was guarded by a Dark Side entity, a parasite living alongside her own essence.

This entity didn't take the intrusion kindly; rather than simply repel her, it consumed her completely, shattering her essence and consuming the energy that remained. Sehtra was not only killed, but completely erased from the Force.

Her energy strengthened Avexiss and her passenger while Sehtra's personality was lost to memory, an ironic legacy from someone who'd wished to live beyond her allotted time.
