Darth Lachris is a character featured in Star Wars: The Old Republic. She is a Sith Lord of the resurgent Sith Empire who was a representative of the Dark Council (and former apprentice of council member Darth Marr), who later becomes the Imperial Governor of the planet Balmorra. She was in charge of eliminating the Balmorran Resistance and dispatched the Sith Warrior frequently to do this.
During the Jedi Order's involvement on Balmorra, Lachris became an enemy of the Jedi Consular known as the "Barsen'thor". In an attempt to intimidate the Balmorran Resistance, Lachris managed to capture the Balmorran President Retheus Galthe and freeze him in carbonite. She was confronted by the Barsen'thor and engaged him in a lightsaber duel. Lachris would ultimately lose the duel.
