Duarmzshee-Paan and her sister, A'Hwiirdh-Paan'A (Harpis) were working as professionals at a bordello on the planet Rashashoon. The Citadel Commander Blackfire recruited them both as mates for soldiers, but both went through considerable genetic modification. When Harpis joined the revolutionary group, the Omega Men, Demonia joined her, though she did not share her sister's passion for justice. Eventually she betrayed the Omega Men and was killed in combat with Tigorr.
