At some point in Zahra's past, she was a service droid designed for the care and maintenance others. For reasons unknown to her, she ceased functioning until a local doctor reactivated her, requiring a droid model to assist in their work. Zahra was given all of their medical knowledge and she willingly aided her master and looked up to them as a parent.

As years went on, her master contracted an incurable terminal illness. Zahra was asked to ignore this condition because cure was impossible, but the talented droid secretly researched a cure, believing that any ailment could be cured with enough research. As days went on, it became more and more clear that she lacked time to find a cure and Zahra decided to take an extreme risk. She tricked her master and carbon froze them, using the underworld technology to massively expand the lifespan of her master by essentially pausing their life.

Zahra resolved to find a cure to her 'parent' at any cost, not realizing that all the people the pair served would suffer in the absence of both. The droid rationalized her actions as a long term investment for the people she abandoned, but failed to account for how much investment was required to create an impossible cure. She now helps strangers in an attempt to learn more medical knowledge at great risk to herself.

Zahra feels an undying loyalty to her master, worshipping them as if they were a godlike figure. Her personal obligation to them was so extreme that she betrayed their requests and froze them so that she could have time to do the impossible feat of treating them.

Zahra is a 5'10" tall droid made of a dark durable metal. Her feminine frame was accented with dark purple coloring and her photosensors were tinted blue to give her a more personable appearance. Her hands were surprisingly sophisticated for a droid, allowing the precise movements needed of a doctor. Her vocabulator replicated a decent approximation of a normal voice, working its hardest to give her the best beside manner possible. She carries basic medical supplies and tries to put on her most appproachable face any droid can hope to muster.
