Tho'natu

Tho'natu was a male Twi'lek Jedi during the final years of the New Sith Wars. As a Jedi Knight, he fought in the Ruusan campaign, and by 990 BBY he had ascended to the rank of Jedi Master. In that year, the Jedi Order received a message revealing that an injured Sith Lord was on the planet Ambria, and Tho'natu and a team of thirteen other Jedi were sent to arrest the Dark Lord. Upon their arrival, they were attacked by the former Padawan Darovit, who Tho'natu and the others quickly killed, believing him to be the Sith Lord. Unbeknownst to the Jedi, Darth Zannah had hidden herself and her Master, Darth Bane—the Sith Lord to whom the message actually referred—and had driven Darovit insane. Erroneously believing the Sith to be eliminated, Tho'natu and the team of Jedi left, resulting in the survival of the Sith Order.
