Darth Mylus, also known as Brianna, "The Last Handmaiden", or simply "Handmaiden", was a half-Echani Sith Lord, and illegitimate daughter to the famous Echani General Yusanis and Jedi Master Arren Kae, who both fought in the Mandalorian Wars. She later served along with her five half-sisters as a handmaiden to Jedi Master Atris in the period following the Jedi Civil War. During her service to Atris at the Jedi Academy on Telos IV, Brianna met the Jedi Exile, and was subsequently tasked with accompanying him on his mission to seek out the Jedi Masters who survived the First Jedi Purge. As the Exile's companion, Brianna helped battle against numerous adversaries, including the resurgent Sith.
