Game of Thrones prequel House of The Dragon has had a number of prophecies so far. A lot of them have come to pass, and there’s another that has recently come to light in episode 9. Alicent and Otto are both trying to sway the unwilling Aegon to be the kind of ruler they want him to be.
Mysaria has risen in power quite significantly from her whorehouse days. When she meets Otto to make a deal with him about the knowledge of Aegon’s whereabouts, she delivers a veiled threat, that’ll come to pass in an important event in the Dance of the Dragons.
Mysaria mentions how the Lords and the Ladies of Westeros are nothing without the smallfolk, and how easy it would be for her to have Aegon killed.
After the suicide of Helaena Targaryen, Queen Rhaenyra was forced to flee King’s Landing. The events that transpired amidst her fleeing with her remaining children saw the small folks in flee bottom rise against the nobility and cause riots.
