Melisandre
Melisandre is a red priestess of R'hllor from Asshai in A Clash of Kings, a striking woman in red robes at the Dragonstone court of Stannis Baratheon who preaches the Lord of Light and reads visions in the flames.
Out of the shadow-haunted city of Asshai, at the far eastern edge of the known world, comes Melisandre, a red priestess of R'hllor, the Lord of Light. She serves at Dragonstone, the island seat of Stannis Baratheon, where her foreign god has begun to win followers, and there she preaches her faith's war of light against darkness and reads what she can of things to come in the flames of her nightfires. She is a tall woman of striking beauty, red-haired and always in red robes, a red-gold choker at her throat, and she unsettles nearly everyone who deals with her. Some at Dragonstone take her for a holy woman, others for something more dangerous; none doubt her conviction, for her faith admits only one enemy, and that enemy is the dark.
