Asha-Mu was a Voss woman, specifically a female, who worked as an aide to Orin-Va. Orin-Va was a healer located at the Shrine of Healing on the planet Voss during the period known as the Galactic War. After the Sith Lord Shendan poisoned Gaden-Ko, a mystic-in-traing, she and Orin-Va provided assistance. With the permission of the Barsen'thor's, Orin-Va employed Voss methods to transfer the life energy of the Jedi to the Voss.
