Vydel Dir'Nul

Vydel Dir'Nul was a human female Jedi Knight with a split personality. She fell in love with a pilot named Ash B'risko, but he fell in love with a Twi'lek. Jealous, Vydel developed the Dark Side alter ego "Kardem," and killed the pilot and the Twi'lek with Force lightning. She went on a killing spree, killing Twi'lek females as "Kardem" with lightning and lightsabre, and, as Vydel, unaware of her alter ego, investigating the murders and chasing "Kardem." The Jedi High Council sent a Jedi Knight to capture her, but she murdered him as well. A bounty was placed on "Kardem," and she was eventually captured by Feskitt Bobb.
