Fan Casting Viserys Targaryen in A Song of Ice and Fire

Prince Viserys Targaryen is the heir of his father, King Aerys II Targaryen, following the death of his older brother, Prince Rhaegar, during Robert's Rebellion. Viserys possesses the classical Valyrian features: he has pale skin, silver-blond hair, and pale lilac eyes. He had been a small, robust, and healthy child, but in his early twenties, after more than a decade of living in exile, Viserys has become a gaunt young man with hard lines in his face and a feverish look in his eyes.
