Alianda, a Human female slave, was characterized by her rounded head.
Around the year 20 BBY, Alianda, estimated to be between twenty and twenty-five years old, was enslaved by the notorious Chevin slaver Phylus Mon. He held her captive on his vessel, the Animiasma. At this point in time, Phylus Mon was attempting to fix a Sith relic called the Darkstaff. This Darkstaff, which had some degree of awareness, was altering the galaxy, specifically the ship, to reflect its own nature. A group dispatched by Jedi Master Lanius Qel-Bertuk stood in opposition to certain actions of Phylus Mon.
To communicate with Qel-Bertuk's team through a tangible form, the Darkstaff took control of Alianda. While possessed, Alianda's eyes turned completely black, and her speech became rough and grating, unsettling those who faced her/it. Once the Darkstaff determined that the negotiation had concluded, it simply vacated Alianda's body. The trauma of being inhabited by such a terrible entity could have resulted in her death, but her survival remains uncertain.
The description of Alianda's voice while under the Darkstaff's control is: "Picture James Earl Jones, but with his throat feeling like it's lined with sandpaper".
