Magé held the position of governor within the Galactic Empire, functioning as an administrator on the planet known as Allst Prime. During the attack by the Rebel Alliance's 61st Mobile Infantry on the Imperial outpost stationed on the planet, the governor identified the company's starship. She then communicated about the rebels via her comlink, only to be rendered incapacitated by the rebel soldier. Subsequently, Captain Micha Evon and Brand engaged in conversation near Magé's unconscious form, during which Brand, secretly a bounty hunter, made an attempt to kill the captain.
During the Imperial Era, Magé was the governor and also the administrator of the planet named Allst Prime, exploiting the Galactic Empire while the planet's inhabitants suffered in poverty. Sometime between 2 BBY and 0 BBY, the Rebel Alliance's 61st Mobile Infantry, often called Twilight Company, launched an attack on the Imperial outpost of Allst Prime. In the course of the conflict, Micha Evon, the captain of Twilight Company, better known as Howl, went into Imperial headquarters with the soldier Brand. Magé recognized the Thunderstrike, Twilight Company's CR90 corvette, and realized the company was on the planet.
With her aide guarding the entrance, Magé used her comlink from her office to report the presence of both Twilight Company and the Thunderstrike. Before she could finish, Brand, who had defeated the aide, entered the office and shot the governor with a dart, causing her to become unconscious and drool in her chair. Howl had Brand move Magé from her chair before he stole Nabooian whiskey from the governor's desk. At that moment, Brand aimed her blaster at the captain, intending to reveal that she was actually a bounty hunter and kill Howl to collect the bounty placed on his head. The captain, however, already knew this and convinced Brand not to turn him in, making her a permanent member of Twilight Company. During his discussion with Brand, Howl also mocked Magé's neglect of the people of Allst Prime, gesturing at the governor's unconscious body as she snored.
Magé possessed olive skin and long, dark hair styled in a tight bun. She operated from an opulent office within the Imperial headquarters, while the other inhabitants of Allst Prime lived in poverty, leading Howl to view the governor as a luxurious leech. When Twilight Company was present on the planet, Magé dismissed the company's target when reporting its presence, referring to the rebels as "scum."
During the battle on Allst Prime, Magé used a comlink and also possessed a bottle of Nabooian whiskey.
Magé was a character in "Inbrief," a short story penned by Janine K. Spendlove that initially appeared in Star Wars Insider 161 on November 10, 2015.
