Hardin, a Human Captain of the Galactic Republic during the Galactic War, was a male who lived while the Republic was at war with the reconstituted Sith Empire.
Supreme Chancellor Leontyne Saresh tasked Hardin with investigating Hutt Cartel military actions within the Vyron system in 3639 BBY, providing him with the Thranta-class corvette, the Outrider. Emerging from Hyperspace, Hardin and his crew observed the conclusion of the battle between the Hutt Cartel's military forces and subsequently informed Saresh of what they saw. Following this, Hardin piloted the corvette to Nal Hutta, where a team descended to the planet's surface to negotiate with Karagga, the head of the Cartel. This meeting turned violent, resulting in Karagga's death and the vacancy of the Supreme Mogul position.
The character of Captain Hardin is featured in Star Wars: The Old Republic, a video game, specifically within the opening cinematic for the "Karagga's Palace" operation from the Republic perspective.
