Nadia Grell was a Jedi Padawan and later the Senator of Sarkhai in the game Star Wars: The Old Republic.
Grell used a double-sided lightsaber and had explosive Force powers that were at times difficult for her to control. Holly Fields voiced Nadia Grell in SWTOR and the digital expansions Rise of the Hutt Cartel, Galactic Starfighter, Galactic Strongholds, Shadow of Revan, Knights of the Fallen Empire, and Knights of the Eternal Throne.
