HBO continues to tease out the upcoming "Game of Thrones" prequel series, "House of the Dragon," with new official set photos of five major characters.

Last week, several paparazzi-style photos from the set made their way online, including images and video of Matt Smith and Emma D'Arcy in costume as Daemon and Rhaenyra Targaryen, respectively. Now, you can see the two actors up close in the official HBO images, along with others.

Below is Olivia Cooke as Alicent Hightower, the daughter of Otto Hightower (also seen below, played by Rhys Ifans) – the Hand of the King.

"House of the Dragon" will take place about 200 years before the events of "Game of Thrones," and based on the cast of characters, be centered around the bloody Targaryen civil war known as the Dance of the Dragons.

Below you can see actor Steve Toussaint as Lord Corlys Velaryon, aka "The Sea Snake," the leader of a large navy and a famed "nautical adventurer."

Then at last we have Emma D'Arcy as Princess Rhaenyra Targaryen and Matt Smith as Prince Daemon Targaryen - the two younger Targaryen royals who will play a key part in the "House of the Dragon" saga.

HBO has already announced that the new show will premiere sometime in 2022. Familiar faces are attached to the project, like coshowrunner Miguel Sapochnik (who directed memorable "Game of Thrones" episodes like "Battle of the Bastards") and composer Ramin Djawadi.
