Maegor Waters

Maegor Waters, formerly known as Maegor Targaryen, is the rider of the dragon Morghul. The first child of the marriage of Lenore Blackwood and Aenys Targaryen, Maegor was expected to one day become Lord of the Seven Kingdoms before the intrigues of court saw the marriage of his parents annulled, his last name stripped from him, his mother executed, and his father dead. After disappearing days after his father's suicide, Maegor has at various times appeared and vanished in Westerosi politics. There have been no confirmed sightings of Maegor or his dragon in the past ten years, but there are a plethora of rumors regarding his exploits in that period.
