The Mute Master is a legendary assassin that leads the order of The Silent Assassins, well-known for his self-imposed silence.
Seeming to be around fifty, The Master is a tan man with dark, closely cropped hair and almond-shaped sea-green eyes, hinting at a Southern Continent origin. He is often seen wearing white robes. Celaena remarks that he had probably been handsome in his youth.
