A Human female named Muriel Corwin existed in the era of the Cold War that occurred between the Galactic Republic and the re-emerging Sith Empire. In the year 3643 BBY, Muriel's brother, Corwin (also known as the "Durasteel Duke"), passed away suddenly. Subsequently, Vala Organa persuaded Muriel to utilize a holographic disguise to take on her brother's persona, the goal being to avert a negative impact on the morale of House Organa. Nevertheless, Muriel was challenged by a bounty hunter who had participated in the Great Hunt, which led to her disclosing her real identity as well as the fact that her brother had died more than a month prior.
