The Dark Woman
An’ya Kuro was a Human female who gave up her name in service of the Force and became the Dark Woman. A mysterious yet respected Master of the Jedi Order during the Clone Wars, the Dark Woman trained several Force-sensitives of later prominence in the Jedi arts. However, it was her failure to successfully train a female student named Aurra Sing—who later earned a reputation as a notorious slayer of Jedi—that caused the Dark Woman to enter into a self-imposed exile on the planet Cophrigin V.
The Dark Woman later returned to the Jedi Order in accordance with the will of the Force to participate in the Clone Wars as a spy.
