You'll be surprised how it ends, Koty!
I don't mean to be Atin(Stubborn), but it also says on Wookiepedia, "Following a heated duel, Bane attempted to transfer his essence into Zannah's body. However, her will proved to be too strong and Zannah defeated him, ending the life of the Sith'ari, yet also validating herself as his successor. Nearly a millennium later, Bane's Sith Order would defeat the Jedi and overthrow the Republic."
