Dragons are coming! 🔥— Portal House of the Dragon Brasil (@PortalHOTD) April 26, 2021House of the Dragon is a prequel to the Game of Thrones series. The Novel series is titled A Song of Ice and Fire. Fire & Blood is the series in which the new show will be based on, and of course, it's also written by George R. R. Martin.The Game of Thrones prequel House of the Dragon is has a budget of 15 mil per episode, this is about to be insane— Patrón Papi (@Dopemanbeaner) April 22, 2021House Of The Dragon gonna be everything we wanted GoT to be. Bookmark this.— OG Slim  (@Jody_McFly) April 26, 2021The story of House of the Dragon will take place 300 years before any of the events in Game of Thrones. Viewers may recognize some names that are mentioned on the screen due to the history of the show, but none of the characters should be making a return from Game of Thrones. Instead, viewers will watch the story of House Targaryen and how they came to power.trying to not get excited about House of the Dragon but the part of my nerd brain devoted to ASOIAF lore is rebooting pic.twitter.com/EoXOgaIMpA— nat + hiatus (@ashesforfoxes) April 26, 2021I desperately need some House of the Dragon crumbs. https://t.co/cMULveUkKY— Ω meg Ω (@wondermeg_) April 26, 2021House of The Dragon has began filming and I cannot contain myself ...next year we eating good.— Kiama. (@1kiama) April 26, 2021There was certainly a mix of reactions on Twitter when it came to House of the Dragon. For many fans, the prequel series is yet another show to watch that may feature some incredible effects or writing from HBO. But for other fans, it's hard to forget about the blunder that happened with Season 8 of Game of Thrones.Season 8 remake would've been better— ً (@nomura115) April 26, 2021we don’t want house of the dragon we want a season 8 remake— 👉🏻👈🏻 (@king0fkingsz) April 26, 2021I swear to GOD if house of the dragon breaks my heart like Game of Thrones did— gummy shark doing crimes (@__hAshBrown__) April 26, 2021someone called firefighter🤣 pic.twitter.com/vrhgNRIG93— A m a r . a l n a s s e r🇸🇦 (@dracula617) April 26, 2021Not much is known other than the cast and the synopsis of House of the Dragon. One great news for most fans and potential viewers is who will be running the series. Rather than the original Game of Thrones show runners, House of the Dragon will have Ryan Condel and Miguel Sapochnik.
