Brynden Rivers (Bloodraven)

A Great Bastard of King Aegon IV by Melissa Blackwood, pale as bone, red-eyed, marked across half his face by a port-wine birthstain in the shape of a raven. Albino sorcerer, master of the thousand-eye web of informers, faithful to the trueborn line. He shot Daemon Blackfyre down on the Redgrass Field, ruled the realm as Hand to Aerys I, and was at last sent to the Wall by Aegon V, where he rose to Lord Commander before vanishing beyond it for good.
