In the final scene of Game of Thrones season 7, episode 7, the Night King and the army of the dead arrive at the Wall and destroy a large portion of it using an undead dragon, Viserion, to blast it with blue fire. This breach ends the Wall’s centuries-long role as a barrier, allowing the dead to march south into the lands of the living. #houseofthedragon #houseofthedragonedit #edit #aftereffects #hbo #rhaenyratargaryenedit #rhaenyratargaryen #danceofthedragons #gameofthrones #rhaenystargaryen #m
