HBO has revealed our first look at the upcoming Game of Thrones spinoff, House of the Dragon, by posting some concept artwork for the show's dragon's online. On the official Twitter account for Game of Thrones, two highly-detailed illustrations were recently tweeted to give fans a peek at what's to come before the show actually begins filming next year. "Dragons are coming. #HouseOfTheDragon begins production in 2021," the tweet reads.

Although plot details are being kept under wraps at HBO, there's still a lot about House of the Dragon that remains unknown. What we do know is that the show will be based on George R. R. Martin's Fire and Blood series, which released its first volume in 2018. Martin will also executive produce alongside Vince Gerardis, Ryan Condal, and Miguel Sapochnik. Additionally, Condal and Sapochnik will serve as showrunners.

House of the Dragon is described as a prequel series, set 300 years before the events of Game of Thrones and primarily following House Targaryen. The Outsider and The Third Day star Paddy Considine has been cast in a lead role as King Viserys Targaryen, a character "chosen by the lords of Westeros to succeed the Old King, Jaehaerys Targaryen, at the Great Council at Harrenhal. A warm, kind, and decent man, Viserys only wishes to carry forward his grandfather's legacy. But good men do not necessarily make for great kings."

Game of Thrones served as a television adaptation of George R. R. Martin's A Song of Ice and Fire novel series. It first premiered in 2011 to immediate success, earning immense critical acclaim and widespread popularity. The show featured an ensemble cast with very memorable performances from actors including Peter Dinklage, Emilia Clarke, Kit Harington, Sophie Turner, Maisie Williams, Lena Headey, and Nikolaj Coster-Waldau. Consistently a big winner at the Emmy Awards, the show rode a wave for many years as one of television's most beloved shows.

Unfortunately, many Game of Thrones fans did not get the ending that they were hoping for when the series came to an end in 2019. The final season was widely panned by viewers with particular criticism towards its final three episodes, which are among the lowest-ranked of the series on Rotten Tomatoes. There was so much backlash against the final season that fans took to signing a petition calling for HBO to completely remake the season with different writers. The petition continues to draw signatures, currently standing at over 1,800,000 names.

House of the Dragon is scheduled to begin production in 2021, on schedule to make its planned release on HBO in 2022. Although Game of Thrones had a bit of a rough ending with a lot of viewers, there are certainly millions of fans who have fond memories of watching the show over the years. Hopefully, the prequel series will be able to recreate some of that same magic for its own run. Let's just hope it manages to stick the landing. The first look at the prequel series comes to us from Game of Thrones on Twitter.
