Who is in the cast of Aegon’s Conquest? Since there has been no official casting at this time, it is still unknown which actors will be involved in the project. Others involved, of whom we know, include screenwriter Mattson Tomlin. According to an interview with The Hollywood Reporter from 2024, he is in contact with George R. R. Martin. So it can be assumed that the author of the books is also involved.

What is the plot of Aegon’s Conquest? The specific plot of the adaptation is unknown, but within the Westeros works, it refers to the conquest of Westeros by Aegon I. Targaryen. He conquered the Crownlands, except for Dorne, and became the first king on the Iron Throne.

His conquest is one of the most significant events in Westeros, as he founded and established the Targaryen family, thereby influencing world history for years to come. The conquest is also part of the calendar. A.C. stands for After the Conquest, meaning After the Conquest.

Aegon’s Conquest could become an important event as a film or series since it was relevant to many elements in Game of Thrones. However, Aegon was not the only one with that name.
