Shiana Atrus is a cheerful but volatile 160-year-old asari, living in Nos Astra, Illium. Formerly a nurse, she was fired as a result of disciplinary action, when she assaulted a doctor to discourage his unwanted advances on her. She and her roommate and partner Alia subsequently found themselves without accomodations, when their apartment building was sealed due to a hazardous fault in the building, which caused substantial damage after the evacuation and rendered the building uninhabitable. The couple stayed with Daia T'Nara for a short time, before finding new accomodations; the stress of the succession of setbacks caused Shiana to briefly contemplate becoming a justicar, before she calmed down.
Although Shiana and Alia are expecting a child (carried by Alia), the pair's relationship is open. Shiana conducted a brief liaison with asari entrepreneur Meria T'Laan, before the latter's departure from Illium.
Shiana posts on CDN using "Caduceus+Chamomile", a joint account with Alia.
