Femon served as a loyal aide to Kueller, a former pupil who had succumbed to the dark side of the Force.
During the Eye of Palpatine's arrival on Almania, Femon's family perished amidst the chaos while attempting to rescue others who were being drawn to the dreadnaught.
She possessed long, ebony hair, an unusually fair skin tone, deep azure eyes, and lips as red as blood. Upon learning that Kueller shared a similar flaw with the New Republic – namely, his reluctance to govern with absolute authority and eliminate his adversaries without hesitation – she ceased her allegiance to him. Kueller then used the Force to fatally break her neck.
Her possession of a death mask collection was a well-known fact. Additionally, she was recognized for applying makeup to her face, creating the illusion of a temporary death mask. She removed this makeup to demonstrate her assumption of control to Kueller, who then murdered her by constricting her throat with the Force and fracturing her neck.
