Kimaru existed as a Nightsister of the Human species on the planet of Dathomir during the era known as the Galactic Civil War.
Kimaru was, at one point, confined within Dathomir's Chamber of Banishment, where her vital essence became ensnared within a sizable crystal. Sometime after 0 BBY, a party of spacers gained entry to the chamber, which resulted in Kimaru's liberation from the crystal. Subsequently, she launched an assault on the group, only to ultimately meet her death.
Kimaru functioned as a non-player character within the 2003 video game Star Wars Galaxies. This game was a massively multiplayer online roleplaying game brought to life by Sony Online Entertainment and distributed by LucasArts, before it ceased operations on December 15, 2011. Kimaru's inclusion in the game was part of the "Axkva Min" Heroic Encounter, which was implemented via the "Chapter 7" update released on November 1, 2007.
