George R. R. Martin performs with prophecy always within the Sport of Thrones books. It is by no means mentioned explicitly that Aegon the Conqueror had the imaginative and prescient described on “Home of the Dragon,” however there’s a scene within the second e book, “A Conflict of Kings,” that means such a prophecy. Whereas wandering by way of the paranormal Home of the Timeless in Essos, Daenerys Targaryen sees a person bearing the silver hair of her household holding a child and talking to a girl who’s supposedly its mom. “He’s the prince that was promised,” the person says, “and his is the music of ice and hearth.”
Most interpret this scene to be Rhaegar Targaryen, Daenerys’ older brother who was killed by Robert Baratheon, speaking to his spouse, Elia Martell, about their son Aegon, who’s killed in infancy. One other interpretation is that he could possibly be speaking to Lyanna Stark, his supposed secret lover, and that the kid is definitely Jon Snow, although it could be odd for Rhaegar to call two completely different sons Aegon. Both method, it is doable that Rhaegar is referring to the Targaryen prophecy handed down by Aegon the Conqueror. The specific reference to Aegon’s dream on “Home of the Dragon” was steered by Martin himself.
The “Prince Who Was Promised” reference entails a separate however associated prophecy — one which’s a lot older.
