Duel on Ambria (990 BBY)

A duel occurred in the year 990 BBY, between the Sith-aspirant Hetton, his eight servants, and Darth Bane, Dark Lord of the Sith. Instigated by Bane's own apprentice Darth Zannah, the duel ensued after Hetton, who had been tricked by Zannah into giving her information regarding the creation of Holocrons, arrived at Bane's camp on the planet Ambria—having been led there by Zannah.

While meditating at his camp, Bane was surprised by the sudden appearance of Hetton's eight Umbaran-trained Sith Shadow Assassins, each armed with their customary Force pikes. Though outnumbered, Bane immediately readied for battle as all eight assassins attacked, attempting to overwhelm him with the strength of their numbers. After cutting down three of them, Bane was interrupted by Hetton, who had Darth Zannah at his side. Hetton then charged Bane, with his five remaining assassins doing the same. However, all were subsequently killed by the superior might and skill of Darth Bane. Hetton was last to meet his demise, and upon ending his life, Bane attacked Zannah. Before the Dark Lord could kill her for her seeming betrayal, Zannah revealed the truth; she had been using Hetton all along, and from him she had discovered information on creating Holocrons, a secret which had eluded Bane until that moment.
