Sivarra Mecheaux existed as a Force-sensitive Human female who resided on Aurilia during the era of the Galactic Civil War. As the medic for her village, she dedicated her time to tending to the injured, victims of attacks perpetrated by the Dark Jedi named Mellichae and his Sith Shadows.
As her village evolved into a larger township, Sivarra's responsibilities as a medic lessened, leading her to begin a new venture: selling useful items to traveling adventurers.
Sivarra Mecheaux appeared as a non-player character within the video game Star Wars Galaxies: An Empire Divided, released in 2003. This game was a massively multiplayer online roleplaying game created by Sony Online Entertainment and distributed by LucasArts. The game's servers were taken offline on December 15, 2011. She was initially present in the village of Aurilia, involved in quests that allowed players to become Jedi, but she and Aurilia were removed in 2005 as part of the New Game Enhancements.
Her character was reintroduced to the game in November 2007 with Chapter 7, along with the updated township of Aurilia. She could be located within a medical facility. However, her role changed to that of a vendor, offering items in exchange for special tokens earned through participation in high-level instance dungeons called "Heroic Encounters".
