Talia was a Dathomirian woman from Dathomir, and she belonged to the Nightsisters as an aide to Talzin. Born on the planetary surface of Dathomir with a sister who was her twin, Talia later encountered Asajj Ventress when she came back to her home on Dathomir. Talia was among the Nightsisters who faced Ventress and were ready to kill her, but Mother Talzin stopped them. Eventually, Talia aided in giving their returned sister the Water of Life and a potion that made one invisible for Ventress and the Nightsister Hunters Naa'leth and Karis to use to get into Count Dooku's palace located on Serenno. Later, she helped Talzin as they journeyed to Serenno aboard a Sheathipede-class transport shuttle in order to present the warrior Savage Opress to Dooku. Talia's life ended during the Battle of Dathomir, where General Grievous commanded Separatist battle droids in an attack against the Nightsisters, an assault that nearly wiped out the clan.
Talia, a female Dathomirian Zabrak, stood at a height of 1.85 meters, which is equivalent to 6 feet and 1 inch. Her features included silver-blonde hair, red eyes, and white skin adorned with gray tattoos. As a member of Mother Talzin's clan, she provided assistance to Talzin in numerous tasks, ranging from the preparation of spells to heal Asajj Ventress, to the presentation of Savage Opress to Count Dooku on Serenno.
Talia possessed considerable power as a Nightsister, demonstrating skill in both armed and unarmed fighting. She also had a strong connection to the Force and possessed great agility.
Talia was skilled in using an enchanted Nightsister blade and wore Nightsister robes that were red in color.
