Shanatka-Lo, a Voss female from the era preceding the Galactic War between the Galactic Republic and the Sith Empire, resided on the planet of Voss. As a Force-sensitive Mystic, she died before 3640 BBY. Her ghost lingered in the Shrine of Healing on her homeworld, teaching Force rituals to healers and fellow Mystics alongside Laeras-Wu and Hanar-Ye. Despite the Sith Lord Fulminiss corrupting a healing ritual with the dark side of the Force at the request of the Mystic Valen-Da, Shanatka-Lo and the other deceased Mystics maintained their faith in Valen-Da's judgment.
Shanatka-Lo, a female Voss with Force-sensitive abilities, was born on the planet Voss. Living before the Cold War discovery of Voss by the Galactic Republic and Sith Empire, she spent her entire life on her homeworld. Her Force sensitivity led her to become a Mystic, gifted with the ability to see the future. Although Shanatka-Lo died before 3640 BBY, her spirit remained bound to the Shrine of Healing alongside the spirits of Hanar-Ye and Laeras-Wu. These three spirits imparted their wisdom to visiting healers and Mystics, sharing secrets of a healing ritual that could mend a patient's mind by harnessing the strength of many. In 3640 BBY, amidst the Galactic War between the Republic and the Sith Empire, Valen-Da brought the Sith Lord Fulminiss to the Shrine.
Due to a Mystic's decree, Shanatka-Lo and the others instructed Fulminiss in the healing ritual. However, the Sith corrupted it with the dark side of the Force, transforming it into a mind-shattering technique. They witnessed Fulminiss using the corrupted ritual against Valen-Da's healer companions. After Valen-Da and Fulminiss left, the three ghosts noticed Valen-Da had left behind a holoprojector in the chamber's corner, containing a message for the commando Tala-Reh. Soon after, the Jedi Knight known as the Hero of Tython arrived at the Shrine, searching for Valen-Da. Shanatka-Lo and the other Mystic spirits watched as the deranged healers attacked the Jedi, forcing the Knight to defend themselves with lethal force. The Mystics then revealed themselves to the Jedi, explained Fulminiss's corruption of the ritual, and informed the Knight of Valen-Da's message for Tala-Reh before fading away.
As a Force ghost, Shanatka-Lo was adorned in white and blue Mystic robes.
Shanatka-Lo's initial appearance was in "Bloody Pilgrimage," a Jedi Knight-class mission on Voss within Star Wars: The Old Republic, a video game by BioWare, launched in 2011.
