Brynden Rivers/Lord Bloodraven in the "House of the Dragon" season two finale.
Sydow's character also doesn't have the same red birthmark on his face as Brynden does in "House of the Dragon."
It's possible this could be explained in "House of the Dragon" with the idea that the Three-Eyed Raven simply managed to change his appearance over time.
Shortly after, the Night King and the White Walkers assault the cave where the Three-Eyed Raven lives.
It's not clear whether Brynden/the Three-Eyed Raven will suffer the same fate in Martin's future books.
