Batha

' "Even a novice could tell those bodies hadn't died of fever." '

Batha is an asari scientist responsible for the vaccine against a batarian biological weapon. She, along with other scientists from settlements near the Batarian Fringe, were kidnapped by batarians and brought to a research facility on the Ahn'Kedar Orbital Platform. Jacob Taylor first arrives at the station while following a lead given to him by Miranda Lawson. Shortly after landing, he encounters Nax who makes it known that he is there to rescue Batha. They agree to work together in assaulting the research facility and rescuing the scientists.

After fighting his way through batarian forces, Jacob finds Dr. Hendricks, one of the recently kidnapped scientists. Jacob tells Hendricks to gather his equipment and prepare to leave, but the scientist declines. Hendricks and the others have been led to believe that they are working on a cure for a recent viral outbreak decimating entire batarian populations. Hendricks admits that he does not have the cure with him, but that a prototype formula is currently being worked on by Batha in another facility, who was taken away before they had a chance to test it.

During their conversation, Jacob hears a commotion. An explosion occurs in the lab and out comes Nax with Batha on his shoulders. After taking out the pursuing batarians, Batha expresses gratitude to Jacob, much to Nax's dismay. Batha mentions that she was working on a vaccine for a "terrible blood plague". She claims to have come close to completion, but that it is still not ready for use. Batha says she will need some items from the ship's sick bay, but also a large amount of unrefined element zero, which is rather difficult to come by. At this point, Miranda suggests they head to Bekke, where she's heard rumors of element zero stockpiles being stashed and protected, likely by batarians.

Batha eventually completes the formula, just in time to cure Illo Nazario and administer a vaccine against the batarian bioweapon to the rest of the crew.
