The Mother of Dragons may be no more. A change from George R.R. Martin's book in House of the Dragon season 3 might have a pretty brutal butterfly effect that would in theory prevent Daenerys Targaryen from ever being born.
In the season 3 premiere, the bloody Battle of the Gullet rages, which results in the death of Jacaerys Velaryon. While the manner of his death is very accurate to Martin's source material Fire and Blood, the show removes Rhaenyra's two youngest sons, Aegon and Viserys, from the battle.
