A Human female with brown hair served as an Imperial Knight for Emperor Roan Fel of the Galactic Empire in the year 130 ABY. When Fel's military forces defeated the Galactic Alliance and emerged victorious in the Sith–Imperial War, his Sith allies turned against him. Upon learning of a planned murder attempt by the Sith Lord Darth Krayt, he chose to flee into exile. To create a diversion while he escaped, Fel dispatched four Imperial Knights, including the brown-haired female, to confront Krayt; Krayt arrived at the Imperial Palace on the Empire's throneworld, Coruscant, and slew all four Knights, declaring himself the Emperor of a new Empire.
During the time of 130 ABY, a female Human character, notable for her brown hair, held a position within the Imperial Knights. These knights were a group of Force-users demonstrating allegiance to Emperor Roan Fel of the Galactic Empire. In that specific year, she played a role in a deceptive maneuver conceived by Fel, targeting the Sith Lord named Darth Krayt. Following the Empire's defeat of the Galactic Alliance and their subsequent triumph in the Sith–Imperial War, Nyna Calixte, the Director of Imperial Intelligence, informed Fel that his Sith allies were planning to betray him. Darth Krayt had a scheme to murder Fel, intending to take control of the Imperial throne at an approaching meeting of the Imperial Moff Council. Before Fel made his escape from the Imperial throneworld of Coruscant, he made arrangements for his double to encounter Krayt within the Imperial Palace, effectively buying him time to flee.
Fel's cousin, Mohrgan, who was an Imperial Knight himself, volunteered to lead a team of three other Knights against Krayt, further supporting the deception. During the meeting, the brown-haired female, along with Mohrgan, another female, and a male, stood guard with the decoy Emperor as he engaged in discussions regarding the war's aftermath with six Moffs. The meeting faced disruption when Krayt and three of his Sith Lords arrived, with Krayt demanding Fel's life. Mohrgan instructed his team to protect the Emperor; however, Krayt ignited two lightsabers and swiftly slew them all, regardless of their attempts to defend. Following this, he struck down the decoy Emperor and declared himself the Emperor of a new Empire. Fel, along with the remaining Imperial Knights, were then forced into exile.
Being an Imperial Knight, the brown-haired female belonged to an order that only accepted members who showed potential in the Force. It was said that the Imperial Knights were some of the most skilled and dangerous Force users present in the galaxy. At the request of Roan Fel, the Imperial Knights did not take part in the Sith–Imperial War; however, the brown-haired female did experience combat with a Sith shortly after the war ended. She and three of her fellow knights were quickly defeated by Darth Krayt's dual lightsabers.
The character of the brown-haired female was first seen in the comic series Star Wars: Legacy's first issue (2006), together with three other Imperial Knights who were also unidentified at the time. The issue was written by John Ostrander and penciled by Jan Duursema. These events were later retold in Legacy's eighth issue (2007), where three of the Knights were still unidentified and one was given the name Mohrgan.
