45. Daenerys’ dragon Drogon, the largest of the three with black and red scales, is considered in the novels to be the reincarnation of Balerion the Black Dread. Balerion was the largest of Aegon the Conqueror’s dragons and was also responsible for the creation of the Iron Throne.

Head of a black bull was served as the symbol of Black Dinner.
