The series premiere of "House of the Dragon" is here, and it's a doozy. The first ever successor series to "Game of Thrones" has gotten off to a resoundingly good start for HBO, already becoming the most successful premiere ever for the network. That's nothing to sneeze at, considering just how long HBO has been in the premium television game.
Yet while "House of the Dragon" is wowing critics and audiences (or scarring them beyond belief, depending on how you reacted to that one horrifying scene), it's already doing a bit of legwork to help set up the greater "Game of Thrones" cinematic universe. It's no secret that HBO has numerous spinoffs in development based on the works of George R.R. Martin. While "House of the Dragon" may end up being a good way to gauge audience appetites for more Westeros, it's already laid some very subtle groundwork for a future show.
