They were to be the foundation of a strength which Atris felt the Order had long since lacked, one who would watch and judge Jedi and provide support should their power corrupt them, and ultimately end those who were thought lost to the dark side. Though their intended purpose was to serve the Jedi, the sisters had all sworn an oath to Atris to never learn their ways. Although Brianna swore not to follow their path, she still honored her parents, and would carry their legacy, donning Kae's Jedi apparel for training and wielding her father's weapon. The shame he brought upon his daughters for the sake of his feelings for Kae, who also betrayed her oaths, was cause for them to run down their little sister, often commenting that things such as betrayal run in the blood, and that she took after her mother. When Kae was exiled from the Jedi Order and joined Revan in the Mandalorian Wars, their father followed, betraying a person to whom he owed his allegiance. The eldest five were seemingly identical, as Echani children born of the same parents were usually indistinguishable to non-Echani the sixth and youngest of them, however, bore the face of her mother, Jedi Master Arren Kae.

Their weapon of choice was a quarterstaff which could collapse into its handgrip Brianna, the youngest sister, kept one such weapon which once belonged to her father. They trained extensively in a variety of combat styles employing close-quarter weaponry and unarmed combat, and they were all highly skilled in the renowned martial art of the Echani and its advanced forms. After the Jedi Civil War, they served as handmaidens to Jedi Master Atris in a secret Jedi Academy on Telos IV. The Handmaiden Sisters were the six daughters of the Echani General Yusanis.
