Is There a Leon in Fire & Blood?
While Fire & Blood chronicles the history of House Targaryen, there is no character named Leon in the book. However, House of the Dragon has introduced original characters before, meaning Ser Leon could be a new addition to the story. Alternatively, he might be loosely inspired by existing figures from Westerosi history. Fans will have to wait and see how his character unfolds when Season 3 premieres.
