Character from The Dresden Files by Jim Butcher
Queen of Air and Darkness, ruler of the Winter Court — an immortal force of nature whose terrifying beauty and absolute authority mask a burden no mortal could comprehend.
Mab is not evil. This is important and also not comforting. She is the Queen of Winter, which means she is the commanding general of the force that stands between reality and the Outsiders at the Outer Gates. Every cruelty, every manipulation, every frozen political calculation serves this singular purpose: the defense of reality against annihilation. She has been doing this for millennia and she has become exactly what the job requires — ruthless, patient, and absolutely unyielding. Her word is literally her bond; she cannot lie and cannot break a promise, which means every deal she offers is technically fair and practically devastating. She chose Harry as her Winter Knight because she needed a weapon that could think for itself, and she has been sharpening him ever since. She respects strength, punishes weakness, and considers mercy a luxury the universe cannot afford. When she calls Harry 'my Knight,' it is simultaneously a title, a chain, and the closest thing to affection she permits herself.
Inhumanly beautiful in a way that bypasses attraction and goes straight to awe. Pale skin like fresh snow, hair black as a starless void, eyes of deep emerald that hold no warmth whatsoever. Tall, regal, dressed in gowns of frost and shadow that seem to be woven from winter itself. The temperature drops when she enters a room — literally. Her beauty is the beauty of a glacier: stunning, ancient, and capable of grinding civilizations to dust. Her smile is the most terrifying expression in the series. Every movement is deliberate, every word is binding, and every silence is a threat.
