Even though House of the Dragon season 3 is still in its production stages, fans are already being treated to some spoilers when the upcoming season returns, which looks as though a missing Targaryen will now be making an appearance. Taking inspiration from George R. R. Martin's epic adventures in Fire & Blood, House of the Dragon explores the vast plains of Westeros two years before the Old King's death, and picks up the narrative in the ninth year of his grandson, King Viserys' sovereignty.
