|Chronological and political information|
- "And my apprentice breaks her leash. Thana's strength in the Force is magnificent, but she's only focused when provoked into a rage."
- ―Darth Gravus
Born into wealth on Dromund Kaas, Thana was very spirited and destructive until her parents discovered she was Force-sensitive at an early age, but they tried to suppress her. She became angry and burned the entire city block. After realizing that she was the only one that had survived, the Sith took her to Korriban and trained her. Thana tore through the trials and the acolytes of the Sith Academy and later earned the attention of Darth Gravus. After Gravus made her into his apprentice, they journeyed to Taris, where Thana would finally sink her teeth into the Republic forces.
While on Taris, Thana encountered a unique Imperial. who rivaled her. Eventually, the Imperial earned the respect of Darth Gravus, the latter considering the Imperial more special than her after she picked up and tortured a Republic guard who only provided second-hand information. Not only was Thana infuriated, but she "broke off her leash" from Gravus. She nonetheless continued her duties in Taris. Later, Thana was captured by the Jedi and detained in a cell of the main Republic HQ; when the Imperial guided the Sith troops in the attack of the complex, he or she met Thana and decided her fate.
Behind the scenesEdit
During the main quest Taris, the Imperial player will encounter her in every turn. If the player is male, they have the option to flirt with her. In the final quest, "No Escape", when Thana learns about the civilians attempting to escape, the player can decide to either keep them trapped and let them die in the station's destruction for dark alignment points or let them go for light alignment points. Afterwards, the player can fight and kill Thana for dark alignment points or let her go for light alignment points. If they do decide to let her go, she will later send a lightsaber to the player stating about her victories in other areas along with several credits. Her unique outfit is avilable on the Cartel Market as "Thana Vesh's Outfit"
