Ros Lai was a Nightsister of Dathomir around 31 BBY.

Biography

Ros posing as "the Rancor."

Lai was the daughter of Nightsister Queen Zalem and an unknown Jedi Knight. When she was very young, her mother killed her father, beginning a resentment which would last the rest of her life.

Quietly plotting her revenge, Ros used the Force to create an illusory disguise. Because of this disguise as a hideously deformed old hag, the other women of the clan called her "the Rancor". She was relegated to the lowly position of tending to the slaves. It was in this capacity that she discovered Quinlan Vos. Posing as a slave, Vos was investigating a plot by Lai's mother to reawaken the ancient power of the Infinity Gate. With Quinlan's help, she killed her mother in an attempt to take control of her clan and the Infinity Gate. However, she was foiled by Vos and taken into custody by him on his return to Coruscant.

In 28 BBY she self published her memoirs, though people didn't believe her story at the time.

During the Clone Wars, Ros Lai was needed by the Jedi Council to get information of the Nightsister's alliance with the Separatists. She also intended to ensure that Ziro the Hutt made good on a debt he owed her. This debt was covered by the Jedi.

She was possibly related to Mei Lai.
