Darth Talon was a female Lethan Twi'lek Sith Lady in Darth Krayt's One Sith as of 137 ABY. Talon was styled with black Sith tattoos covering her body, head, and lekku; each having been earned in ritual combat and inscribed by Darth Krayt himself. As a Sith apprentice, Talon was trained by a fellow Twi'lek Sith Lord named Darth Ruyn, whom she later killed on Krayt's command with a swift decapitating strike of her lightsaber, shortly before ascending to the rank of full fledged Sith Lord herself.
Recognizing her unshakable loyalty, Krayt had Talon become one of his two Hands, extensions of his own will. In this capacity, Talon found herself working alongside the other of Krayt's Hands, Darth Nihl. Talon was often tasked with her master's most important missions; including the capture of Cade Skywalker. Indeed, for a short time, Talon acted as the Sith Master of Skywalker, however, he soon renounced the Sith, injuring Talon in the process; though she survived, her position in the eyes of her master was severely undermined.
