Corwin, referred to as The Durasteel Duke, was a Human of male gender. He held the position of duke throughout both the Alderaan Civil War and the Cold War that occurred between the Galactic Republic and the reconstituted Sith Empire.
Corwin was a figure of renown, a local legend, and a politician. He was both charismatic and fearless, never retreating when faced with threats or intimidation, and always confronting his rivals directly. Circa 3643 BBY, he was a target within the Great Hunt. A bounty hunter located him, only to learn that Corwin had already passed away and was being impersonated by his sister to strengthen the morale of his family.
